MODEL 2100

DESCRIPTION

The Model 2100 Interactive State Analyzer (ISA) is a powerful
tool for designing, debugging, and evaluating software-intensive
systems. It installs in the pAnalyst 2000 Mainframe and operates
under the control of your IBM-compatible personal computer.
The state analyzer's hardware consists of a controller board
and expandable memory boards. These boards plug into the expansion slots located within the pAnalyst mainframe chassis. You can
configure the state analyzer with 16 to 80 acquisition channels, using
any combination of the following board types:
•

Controller Board (one required)-provides synchronous
clocking, triggering, and control logic.

•

16-Channel Memory Board (optional)-provides 16 acquisition
channels with 4096 bits-per-channel memory.

•

32-Channel Memory Board (optional)-provides 32 acquisition channels with 4096 bits-per-channel memory.

A minimum state analyzer configuration consists of the controller
board and at least one memory board.
Once installed in the mainframe, the state analyzer is
controlled by menu-driven operating software. This software is contained on the pAnalyst's SYSTEM and HELP DISKS.
The various software menus are both easy to learn and use.
They control all facets of the analyzer's operation, including clocking,
triggering, storage qualification, and data display. They also control
linked operations between the state analyzer and other pAnalyst
products, such as the Model 2200 Interactive Timing Analyzer:
The rest of this section discusses the state analyzer's key
features and system components. It also gives you a complete list of
hardware specifications and software characteristics.

1 Introduction _ • • • • • • • • • • •_
MODEL 2100

KEY FEATURES
Key features of the Interactive State Analyzer include:

1-4

•

Universal Clocking-Five external sample clocks make the
state analyzer compatible with virtually any type of
microprocessor system. You can use one or all of these sample clocks to synthesize a master sampling clock. The clock
lines are logically ORed, and they each provide a data sampling rate up to 10 MHz.

•

Single-Probe Demultiplexing-Two hold clocks let you demultiplex data without double probing. You can use these clocks
to latch and hold data until the master sampling clock is
valid. The demultiplexing is all handled internally by the state
analyzer.

•

15-Level Triggering and Storage Qualification-You have up
to 15 trigger/store states at your disposal when defining a
trigger. Each state contains four word recognizers, which can
be arranged in powerful IF-THEN-ELSE sequences that perform such actions as activating the trigger, branching to a
different state, or qualifying data for storage.

•

Multiple-Preview Acquisition-A special acquisition mode
enables you to acquire a qualified event, as well as to capture the seven events directly preceding that event. This gives
you all the benefits of storage qualification, plus the ability to
trace information leading up to each qualified event.

•

Acquisition and Reference Memories-The state analyzer's
acquisition and reference memories can be displayed in hexadecimal, octal, binary, or ASCII radices. You can view these
two memories side by side, and make continuous acquisitions
until both memories are equal or not equal. The differences
between the two memories are highlighted on the display
screen.

•

Histogram Overview Displays-The state analyzer's histogram
display lets you view an overall picture of system activity. In
this display, acquired events are binned into user-defined
ranges, and you see a histogram readout of the percentage
of activity falling within each range.

. . . . . . . . . . . . . . . . . . . . . . . . 1 Introduction
MODEL 2100

•

Time Stamp Measurements-You can add a Time Stamp
Board to the state analyzer at any time. This board provides
a 20 MHz asynchronous clock that lets you measure the realtime execution of your software code. The time distribution of
recorded events is shown in the state and histogram displays.
(See Related Products and Options at the front of this
manual.)

•

Mnemonic Disassemblers-The state analyzer offers a wide
variety of mnemonic disassemblers which can convert
acquired microprocessor software back into an assembly
source listing format. Each disassembler comes equipped
with its own disassembly software and a single-plug probe
connector. (See Related Products and Options at the front of
this manual.)

•

Time-Aligned Displays with Timing Analyzer-The state
analyzer can share the pAnalyst mainframe with the Model
2200 Interactive Timing Analyzer (see Section 6 of this
manual). A cross-aligned mode lets you operate the two
analyzers in tandem, where state events arm timing acquisitions, or vice versa. The state and timing data is then timecorrelated on the display screen.

•

110 Utilities-Mass storage is available through the state
analyzer's interface to the personal computer. You can save
menu setups and reference data on disk, then recall them at
any time. You can also make permanent records of setups
and data by using an IBM-compatible printer.

•

ttAnalyst Interface Board

•
•

PC Interface Board
48-inch Interface Cable
The following paragraphs explain how to connect the various
pieces of the interface hardware. For these procedures, you also
need access to your personal computer manual.
Installing the pAnalyst Interface Board
The pAnalyst interface board is installed in the pAnalyst mainframe at the factory and resides in the mainframe's expansion slot 1.
You do not need to perform any preliminary installation of this board.

2-8

. . . . . . . . . . . . . . . . . . . . . . . . 2 Installation
MODEL 2100

If you ever want to remove and re-install the pAnalyst interface board, simply follow the procedures contained later in this section under Installing the State Analyzer Boards. The only rule
regarding the installation of the interface board is that it must reside
in slot 1.

Installing the PC Interface Board
If you purchased your personal computer from Northwest
Instrument Systems, Inc., the PC interface board is installed at the
factory. It resides in the computer's option slot area and is indicated
by a label reading p.ANALYST-PC INTERFACE CARD.
If you are not using a personal computer purchased from
Northwest Instrument Systems, Inc., you must install the PC interface
board as described below.
[B'" NOTE
These procedures are based on an IBM Personal Computer. If you
are using an alternate, compatible computer, consult that computer's
manual for instructions on how to install option boards.

1. Turn off your personal computer and disconnect it from any
power source. Also turn off any external power switches to
printers, etc.
CAUTION
You can damage your personal computer or PC interface board if
you install the board while the computer is receiving power.

2. Gain access to the computer's internal expansion slots. When
doing this, follow the procedures, and adhere to any cautions
and warnings, specified in your computer manual.
3. Choose the expansion slot you want to use for the PC interface board; any unused slot is appropriate. Then, using a
screwdriver, remove the screw that holds the expansion slot
cover in place. Lift the slot cover up and out.
4. Locate the address switches on the PC interface board.
These switches determine the computer memory range that
will be used by the pAnalyst interface.
The switches are factory-set for the address range DEOOODEFFF, hexadecimal (see Figure 2-6). You can reset these
switches for any 4K bytes of contiguous memory addresses,
as long as the memory addresses are not used by another
part of your computer.

2 Installation . . . . . . . . . . . . . . . . . . . . . . . ..
MODEL 2100

The polarity of the switches is inverted so that ON=O and
OFF=1. The switches set the most significant 8 bits of the
address range only; the lower 12 bits of the range are always
OOO-FFF, hexadecimal.
[B" NOTE
If you're using an IBM PC AT, these switches must be set to the
default address range of DEOOO-DEFFF to avoid collision with the
computer system's ROM.

5. Insert the PC interface board into the computer's expansion
slot, as shown in Figure 2-7.

Installing and Removing Boards

Figure 2-10 illustrates how the mainframe looks when the top
cover is removed. Seven expansion slots, labeled 1-7, are contained
in the card cage. Each slot consists of two parallel connectors located
at the bottom of the mainframe on the backplane circuit board. You
can read the individual slot numbers in the open area of this backplane circuit board, or you can read them on the mainframe's back
panel.
Slot 1 is dedicated to the ~nalyst interface board. Slots 27 are available for housing the state analyzer and other pAnalyst
products.
There are only two rules regarding the placement of the
analyzer's boards: 1) the controller board and all memory boards
must be installed in contiguous slots; and 2) the controller board
must be installed in the lowest numbered of these contiguous slots.

IB"" NOTE
The recommended placement of the state analyzer boards is the
controller board in slot 2, and one to five memory boards in slots 3
to 7. This placement matches factory configurations.

Replacing the Mainframe's Cover

To replace the mainframe's top cover, simply reverse the
procedures shown in Figure 2-9 as follows:
1. With the clips toward the front of the chassis and the
threaded tabs toward the back, lower the top cover into the
grooves along both sides the mainframe at a slight angle,
back higher than front.

2. Gently push the cover forward to engage the clips at the
front of the mainframe. There should be a slight gap between
the front of the top cover and the step at the rear of the
upper surface of the front panel.
3. Lower the top cover and engage the sides into the grooves
of the side rails, all along their length. The cover should sit
just above the top of the back panel, with the two threaded
tabs aligned with the two holes in the back panel.
4. Replace the screws in the upper left and right corners of the
mainframe's back panel.

CONNECTING THE PROBES

The state analyzer comes equipped with one P2901 Clock
Probe and with one to five P2902 Data Probes. The exact number of
P2902 Data Probes depends on the number and type of memory
boards included in the analyzer package.
The P2901 Clock Probe is used with the controller board. It
provides 11 user-accessible channels, arranged as five sample clocks,
two hold clocks, two real-time programmable outputs (RPOs), one
run/stop indicator output, and one ground line.
The P2902 Data Probes are used with the memory boards.
One probe is required for 16-channel memory boards, and two
probes are required for 32-channel memory boards. Each probe provides 16 channels of data input and one ground line.
Tables 2-1 and 2-2 describe the signal characteristics of the
P29_01 and P2902 probes.

THE p,ANALYST SOFTWARE
The pAnalyst's software package contains three diskettes:
•

SYSTEM DISK for 512K-runs on computers that have a
memory capacity of 512K or greater.

•

SYSTEM DISK for 256K-runs on computers that have a
memory capacity of 256K or greater.

•

HELP DISK-runs on computers that have a memory capacity of 256K or greater.

Each SYSTEM DISK contains the entire pAnalyst menu operating software. Only one is required per system. Use the SYSTEM
DISK that fits the memory capacity of your personal computer.
~NOTE

The SYSTEM DISK for 256K memory has certain limitations. For
details, refer to the front of this manual, under the page titled
Software Versions Covered in this Manual.

The HELP DISK can be used with either 512K or 256K of
computer memory. This diskette is not required for operating the
pAnalyst, but it is recommened. It provides a Help Information System
that is comprehensive and extremely useful. In addition, it provides
demonstration and training programs that will assist you in learning
the state analyzer's features and operations (see Section 7 of this
manual).
The rest of this section shows you how to load and operate
the SYSTEM and HELP DISKS.

USING DISKETTES

Diskettes require special care in handling and storage. When
using diskettes, you should always observe the following rules:
•

Hold diskettes by their upper left or right corners. Never
touch their exposed recording surfaces (see Figure 3-1).

•

Never fold or bend diskettes.

•

When diskettes are not in use, store them in their accompanying paper envelopes.

•

Store diskettes in a dry area with temperatures between
10°-52° C (50°-125° F).

•

Never expose diskettes to magnetic fields, such as those
surrounding permanent magnets or electronic motors.

COPYING DISKETTES FOR BACKUP

When you first unpack the pAnalyst diskettes, place adhesive
tabs over their write-protect notches. Then use the diskettes to make
back-u p copies.
The procedures for making back-up copies are listed below.
These procedures assume that you know how to use the DISKCOPY
command. If not, refer to your DOS reference manual.
To make back-up copies:
1. Install a bootable DOS diskette (version 2.00 or higher) into
drive A of the personal computer, then turn the computer on.
2. Now, use the DISKCOPY command to copy the files from the
pAnalyst's SYSTEM DISK (source diskette) to a new, blank diskette (target diskette).
3. Finally, use the DISKCOPY command to copy the files from
the pAnalyst's HELP DISK (source diskette) to the another
new, blank diskette (target diskette).

3-4

. . . . . . . . . . . . . . . . . . . . 3 Gettina Started
MOts'EL 2100

~NOTE

The DISKCOPY command automatically formats the target diskettes
when it copies the files.

Continue using the above procedures to make as many
back-up copies as you want. When you're finished, put the writeprotected diskettes in a safe place, and use the back-up copies for
operating the pAnalyst.

USING A FIXED DISK

As an alternative to using diskettes, you can install the
pAnalyst software in a fixed disk. This fixed disk must contain the
DOS operating system (version 2.00 or higher), and it must have at
least SOaK bytes of free disk space.
~NOTE

For a complete list of compatible fixed-disk computer systems, refer
to the page titled PC Compatibility Requirements at the front of this
manual.

You install the pAnalyst software in a fixed disk by executing
the FINSTALL batch file as described below. This batch file is contained in the pAnalyst's SYSTEM DISK. When it is executed, the batch
file creates a subdirectory titled ANALYST at the root level on the
fixed disk. It then copies all of the pAnalyst system and help files into
this subdirectory.
To use the FINSTALL batch file:
1. Power up your fixed-disk computer, and if necessary, load the
DOS operati ng system.
2. Insert the pAnalyst's SYSTEM DISK into drive A (the floppy
disk drive of the fixed-disk computer).
3. Enter drive A.
4. Type the batch file command:
FINSTALL C: (where C is the fixed-disk drive of
your computer.)
Then press the return key.
5. Follow the on-screen instructions provided by the batch file. A
message on the screen will tell you when the copying procedure is complete.

MODEL 2100

DATA ACQUISITION MODES

The Interactive State Analyzer has two data acquisition
modes: the standard mode, where data is sampled and stored
according to the storage qualification established in the Trigger-Store
Menu; and the Multiple-Preview Acquisition (MPA) mode, where a
sequence of unqualified data occurring before each qualified event is
also stored.
Standard Data Acquisition Mode

In the standard data acquisition mode, data is sampled at
each sample clock cycle and compared to a set of word recognizer
values specified in the Trigger-Store Menu. Qualified data (data words
matching the events programmed in the storage qualification IF
THEN STORE line of each state) is stored when the comparison is valid. The trigger event is always stored, too.
As an option (in the Trigger-Store Environment Submenu),
you can also program the analyzer to store each event that causes a
state transition. Since state names are stored along with the event
that caused the state transition, program flows are easily traced. The
demonstration example in Section 7 uses this capability to follow the
operation of the demo circuit board.
Multiple-Preview Acquisition Mode

Qualified data storage is a powerful feature that allows you
to define what kind of data to store, and ignore the rest. MultiplePreview Acquisition (MPA) extends this concept, enabling you to solve
more complex problems.
For example, suppose you know that a certain event is
associated with a failure. You could try to find the cause of the failure
by triggering on the failure-related event and looking at the data
preceding it. But if the failure is intermittent, you would be forced to
start the logic analyzer repeatedly until the cause was captured. MPA
helps solve this kind of problem.
In MPA mode, the state analyzer's hardware is reconfigured
so that data is stored continually while the machine waits for a qualified acquisition. When qualified data is detected, up to seven of the
previous unqualified events are retained in memory, while the storage
process begins again, until the system triggers. This process is illustrated in the example shown in Figure 4-1.

As shown in the example, unqualified data storage first fills
location 1, then location 2, and so forth with each sample clock. If no
qualified data is detected before location 8 has been written, new
unqualified data overwrites location 1, then 2, and so on. In this particular example, a qualified event is finally detected and stored in
location 6. Locations 7-8 and 1-5 now contain unqualified data stored
on the seven sample clock cycles immediately preceding the
qualified event.

On the state display, you will generally see data displayed as
multiple groups of eight words. The qualified words (those matching
the IF THEN STORE line in the Trigger-Store Menu) are
marked with a right arrow symbol (».
In Figure 4-2 you can see that several qualified events
occurred within eight sample clocks of one another. In this case, storage continues in the same group of eight locations, and then
immediately continues in the next group of eight. In this example, the
event in location 8 happened to be qualified.

MODEL 2100

If the event in location 8 had not been qualified, the acquisition could have continued in much the same way as the acquisition
represented in Figure 4-3. As in the example in Figure 4-2, several
qualified acquisitions are made within eight sample clocks. When all
eight locations in the current group are filled, new unqualified
samples are stored in the next group.
If a qualified acquisition occurs before all the locations in this
group of eight have had data stored in them once, this is treated as a
special case in the state display. Note, in the state display to the right
of Figure 4-3, that there are no blank lines bE?tween the two groups of
eight unqualified events. Data not separated by blank lines is
acquired on successive sample clocks, while a blank line between
two lines of data indicates that an indeterminate number of sample
clocks occurred between these two events.

As an example of how useful MPA mode can be, suppose
you are debugging a program module you've just written. One bug
seems to be associated with a global variable accessed by other
modules you did not write. You could use the standard data acquisition mode to monitor the reading and writing of this variable by
qualifying storage on the variable address, but this would not enable
you to store the code that caused the variable to change. With the
MPA mode, using the same storage qualification and triggering, the
state analyzer will capture the executing code causing each of up to
512 accesses to this variable. Now you can search out the bug by
looking back through the data acquired before the trigger.
[]3"'NOTE
For a more detailed example of how to use the MPA mode, refer to
Section 7 of this manual.

CLOCKING OPTIONS

The Interactive State Analyzer features a sophisticated clocking scheme. The P2901 Clock Probe provides seven input signals for
use in establishing the synchronous sample and hold clocks. It also
provides three output signals, the Run/Stop line and the Real-Time
Programmable Outputs, which can be used for interacting with the
system under test.
The following paragraphs describe how these input and output signals are used. The sample clocks, hold clocks, and Run/Stop
signal are all programmed in the Format Menu. The Real-Time
Programmable Outputs are programmed in the Trigger-Store Menu.
[]3"'NOTE
Detailed procedures for using the state analyzer clocking options to
acquire data from various microprocessors are provided in Appendix
C of this manual.

Sample Clocking
The sample clocks determine the time at which the state
memory boards sample synchronous data. There are five sample
clocks, which are ORed together to create the master clock. They are
labeled S1 through S5 on the clock probe.
As you can see from the example in Figure 4-4, when the
sample clocks do not overlap in time, they produce a master clock
consisting of pulses contributed by each of the sample clock pulses.
When the sample clocks do overlap, the master clock, which
is the sum of all the sample clocks, merges the pulses to create a
longer pulse.

The polarity of the slope on the sample clocks affects the
of the clocks. Figure 4-5 shows how a simple change of polarity changes the master sample clock considerably. One way to look
at this is in terms of clock periods. By defining the trailing edge of
the clock, you are also defining the period from the leading to the
trailing edge to be used in ORing the clocks together.

Hold Clocks and Demultiplexing
For microprocessors or systems that multiplex data and
addresses onto the same bus, the Interactive State Analyzer provides
a convenient way to demultiplex the signals. Through the Format
Menu, you can select multiplexed or non-multiplexed acquisition for
each data probe.
Figure 4-6 illustrates how the data channels from a probe are
routed to the word recognizers. Typically, all 16 channels are routed
via Path A. In the multiplex mode, however, the probe's upper 8
channels (08-015) are ignored and only its lower 8 channels (00-07)
are acquired. These lower 8 channels are sampled subject to
different hold clocks on Path B.

The two hold clocks available for demultiplexing are labeled
H1 and H2 on the clock probe. Figure 4-7 illustrates sample and hold
clocking and demultiplexing.

-1!J this examQle. sample clocks 81, 82, and 83 are connected
to the RD, WR, and INTA strobes of the microprocessor. Their polarities are all set to positive (in the Format Menu), because their trailing
edges are positive-going. 81 and 85 are not connected, and so are
set to off.
The least significant 8 bits of the data probe (bits 00-07)
have been connected to the ADO-AD7 lines on the microprocessor,
which carry multiplexed address and data information.
The hold clocks enable the state analyzer to demultiplex this
bus and acquire both address and data simultaneously. Inside the
analyzer, the probe lines 00-07 are split into two paths, one for
addresses and one for data. Each path is sampled by a hold clock,
and the resulting address and data are held until the master clock
occurs. When the master sample occurs, the address and data are
both stored in memory.
In Figure 4-7, H2 (hold clock 2) is connected to the
microprocessor's ALE (Address latch Enable). H2 has been programmed in the Format Menu to be high pass, low hold. This means
that the address and data lines will pass transparently through the
H2 presample latch while ALE is high, and will be latched, or held,
when ALE goes low. The data gathered by the presample latch is
represented in Figure 4-7 by Group A. As you can see from the
diagram, the microprocessor's valid address (the lower 8 bits) has
been latched and held so it can be clocked into the analyzer by the
master clock.
Notice, in Figure 4-7, that the data portion of the address and
data (73, 44, 32) has shifted slightly to the right in Group D. This happens because H1 (hold clock 1) is connected to the microprocessor's
elK signal. H1 has been programmed to be low pass, high hold.
The microprocessor data is held in the H1 presample latch for nearly
half a microprocessor clock period after it has changed on the
address/data lines. H1 will generate data hold times only if the
microprocessor sygem allows the data to go invalid before the end of
its data strobes (RD, WR, and INTA, for example).

Run/Stop Line

The Run/Stop line is an output generated by the state
analyzer to indicate the run/stop status of the analyzer hardware. Its
output polarity can be programmed in the Format Menu as either
high for run and low for stop, or vice versa.
Real-Time Programmable Outputs

The Real-Time Programmable Outputs, labeled RP01 and
RP02 on the clock probe, are user-programmable outputs. They can
be programmed to change value with the transitions from state to
state while the analyzer is running. The RPOs are programmed in the
Trigger-Store Menu, where you define what logic levels the RPOs
should output at each state transition_

TRIGGERING OPTIONS

The flexibility of the Interactive State Analyzer, which provides
you with the tools for homing in on the sources of problems, is based
on its programmable state machine. Here are its key features:
•

Fifteen independent states controlling triggering and state
sequencing, storage qualification, and three programmable
external outputs (the RPOs) and the Crosslink line (the CL).

•

Two word recognizers per state to control triggering, state
sequencing, and the programmable outputs.

•

Two word recognizers per state for data storage qualification.
You can program the fifteen states to detect sequences of
events, including branching sequences. Six variations of IF-THENELSE programming logic are available, as shown in Figure 4-8.

A. IF OCCURS (1-4096) TIMES THEN (GOTO or TRIGGER).

B. IF OCCURS (1-4096) TIMES THEN (GOTO or TRIGGER).
ELSEIF OCCURS ANYTIME THEN (GOTO or TRIGGER).
C. IF OCCURS AFTER (1-4096) (SAMPLE or STORE) CLOCKS THEN
(GOTO or TRIGGER).
D. IF OCCURS AFTER (1-4096) (SAMPLE or STORE) CLOCKS THEN
(GOTO or TRIGGER).
ELSEIF OCCURS ANYTIME THEN (GOTO or TRIGGER).
E. IF OCCURS BEFORE (1-4096) (SAMPLE or STORE) CLOCKS THEN

(GOTO < state> or TRIGGER).
ELSE (GOTO < state> or TRIGGER).
F. IF OCCURS BEFORE (1-4096) (SAMPLE or STORE) CLOCKS THEN
(GOTO or TRIGGER).
ELSEIF OCCURS ANYTIME THEN (GOTO or TRIGGER) .

•

4·14

. . . . . . . . . . . . . . . . . . . 4 Modes of Operation
MODEL 2100

The simplest trigger mode is mode A:
IF OCCURS (1-4096) TIMES THEN (Gom
< state> or TRIGGER).

In this mode, events are counted until the total matches the
preset value, and then the action is taken. Like all versions of the
state program, until the IF or ELSEIF condition occurs, data is stored
according to the storage definition specified below the two IF-THENELSE definitions in each state. When the definition is satisfied, control
is transferred to another specified state or the system is triggered
(which means that acquisition ends, subject to the trigger position
programmed at the top of the Trigger-Store Menu). During this transition the Real-Time Programmable Outputs (RPOs) and the Crosslink
(CL) are set to the new values defined in the state you are leaving.
Trigger mode A is useful for identifying particular events or
setting up looping conditions. For example, you could define the state
as follows:
IF RESET OCCURS 0001 TIMES THEN TRIGGER.

Data will be qualified and stored continuously until the
RESET is detected, and then acquisition will stop. Qualified data leading up to the RESET will be stored and displayed, so you can see
what caused this condition.
An additional ORed event added in mode B expands this
flexibility. The first event takes precedence over the second if the two
occur at the same sample.
Building on the preceding example, a more elaborate
definition is:
IF RESET OCCURS 0001 TIMES THEN TRIGGER
ELSEIF PROC1 OCCURS ANYTIME THEN GOTO < 2 > ,

where PROC1 stands for procedure 1 (so named in the Symbol
Menu).
Now we can look for occurrences of RESET that come before
PROC1. If the GOTO < 2 > were changed to TRIGGER, we would be
looking only for RESET or PROC1 to occur before triggering.
Another valuable capability offered in mode C is counting
clocks. You count sample clocks (the five system clocks ORed
together to generate the master clock, according to specifications in
the Format Menu) or store clocks (the sample clocks that correspond
to storing qualified data).

4-15

4 Modes of Operation . . . . . . . . . . . . . . . .~
MODEL 2100

The addition of ELSEIF to mode C gives you mode D. Here's
a trick for setting up three ORed events:
IF ANY VALUE OCCURS AFTER 0001 STORE CLOCKS
THEN GOTO <2>
ELSEIF THEN GOTO <2>
IF OR < event 2> THEN STORE

Event 1 and event 2 cause their respective data to be stored.
When one store clock occurs, the top IF line is true. The ELSEIF line
is the third ORed event. The disadvantage of this technique is that,
for this state, only event 1 or event 2 data is stored. This mode is
useful for the ORed recognition of three events which move to
another state with less restrictive data qualification.
Modes E and F, using the BEFORE parameter, open a window of a specified number of sample or store clocks. If the event
occurs when the window is open, the first action will be taken. In
mode E, if the event fails to occur before the count is completed, the
second action is taken automatically. In mode F, the second action is
an ORed condition that can occur at any time before or after the
count is completed.
The following diagram illustrates the differences between
modes E and F.

Let's see how you can define a state or sequence of states
that tests indefinitely until a condition is met and the proper data
stored. Consider this state definition:
IF IOERR OCCURS BEFORE 0020 STORE CLOCKS THEN
TRIGGER
ELSEIF TRAP1 OCCURS ANYTIME THEN GOTO ,

where 10ERR is an 1/0 error and TRAP1 is a procedure designed to
catch the error.

. . . . . . . . . . . . . . . . . . . 4 Modes of Operation
MODEL 2100

This allows you to narrow in on a very specific problem. You'll
find out what causes the 1/0 error to occur within 20 qualified data
events of entering the state. The ELSEIF condition provides a way to
restart acquisition when the error has been handled properly.
Several additional examples of state machine programming
are described in detail in the demonstration exercises in Section 7.

STORAGE QUALIFIER OPTIONS

Figure 4-9 illustrates the storage qualifier options available in
the state machine.

A. ALWAYS- > STORE
B. IF/name OCCURS THEN-> STORE
C. IF/name OR/name OCCUR THEN-> STORE
D. IF/name AND/name OCCUR THEN-> STORE

E. NEVER- > STORE

• Figure 4-9. Storage qualifier options.

Two word recognizers are available for data storage qualification in each state. The five modes listed in Figure 4-9 show the combinations available.
The simplest is mode A: always store all sampled data.
Mode E sets the state to never store data, just as mode A
sets the state to always store. Mode E is useful in conjunction with the
acquisition mode to store all state transitions (as specified in the
Trigger-Store Environment Submenu). Then the only storage is the
movement between states, that is, the causes of state transitions.
Mode B uses one event to qualify storage. The event can be
as loosely defined as a control line, such as store all 1/0 accesses or
all READ accesses, or it can be as tightly specified as a single data
value stored into a variable. Similarly, the NOT selection for the event
can also be loosely defined, for example, as store all bus cycles
except 1/0 cycles, or tightly defined, for example, as store when the
variable is written to a value that is not a given value.

4-17

4 Modes of Operation . . . . . . . . . . . . . . . . ..
MODEL 2100

Mode C, the ORing of two events for storage, is useful for
more complex storage qualification. In MPA mode, you can see code
and stack information leading up to two separate procedures defined
by the two events. The ORed combination of two events can also be
used to obtain a range of addresses outside the strict binary range
with just one event.
For example, suppose you want to trace code accessing a
data array that starts at hexadecimal address 1240 and ends at 1284.
The address range can be split out as follows:
1240-127F, or 1280-1284

Event 1 is programmed to the value 1240 with a mask FFCO.
Event 2 is 1280 with a mask FFFC.
With MPA mode on, this storage qualification will display
code that accesses any element of the array. This ORing technique
does not support full-range recognition, but it does permit an approximate area of values that can cover the range required, although it
may overlap additional values.
Mode D, the AN Ding of two events, may seem not to be useful, because all channels are ANOed together to form one count. But
it is useful when one event recognizes one portion of the channels
and the other is set to a not value of another portion.
For example, to store all writes to address B7F2 with a data
value not equal to 20, you would program event 1 for address=B7F2
and event 2 for data=20. The following store line would provide this
setup:
IF and I THEN ->

RUN (GO) MODES

Several run modes are provided by the Interactive State
Analyzer. These modes are selected in the Display Environment Submenu, and they are started by pressing G for Go from the command
line. Each run mode is introduced below:
• GO ONCE-The analyzer gathers data until a trigger is
found. The acquisition continues until memory is filled with
the specified amount of post-trigger data. The amount of preand post-trigger is specified in the Trigger Position field in the
Trigger-Store Menu.
• GO FOREVER-The analyzer takes successive acquisitions.
This mode is often used while viewing either the Display or
Histogram Menu. The analyzer updates the display or histogram automatically with each new acquisition.

4·18

. . . . . . . . . . . . . . . . . . 4 Modes of Operation

•

GO TIL ACO = REF-After each acquisition, the analyzer
compares acquisition data to the contents of reference memory. The acquisitions continue until the two memories match.
(The comparison parameters are set up in the Display
Environment Submenu.)

•

GO TIL ACO < > REF-After each acquisition, the analyzer
compares acquisition data to the contents of reference memory. The acquisitions continue until a difference between the
memories is found.
Both GO TIL ACO = REF and GO TIL ACO < > REF can
be used to help isolate intermittent problems.

In addition to the above modes, the state analyzer provides a
special feature that lets you acquire data until a memory overflow is
detected. This feature is useful when you cannot establish an
appropriate trigger. Once started, the analyzer periodically checks
acquisition memory and stops acquisition the first time it detects a
memory overflow condition.

STATE DISPLAY & ANALYSIS

Once data is acquired, you can use the Display Menu to
view the data in a columnar, radix format. You can also make acquisition and reference memory comparisons.
State Display

The organization of the Display Menu is set up through the
Format Menu. You can organize incoming channels into logical
groups, with each group containing from one to 32 channels. You
can also name the groups and specify their display radices as hexadecimal, octal, binary, or ASCII.
The Display Menu shows the data in columns that reflect the
selected channel groups and their radices. Special command-line
functions are provided that allow you to scroll the display window to
the portion of memory you are interested in. You can page backwards and forwards through memory, or you can jump to any specific
memory location.
Reference Memory Comparisons

At any time, you can transfer acquisition data to the reference
memory, then compare new acquisitions with old. The boundaries of
this data transfer and comparison are set up through the Display
Environment Submenu.

4·19

MODEL 2100

Display modes are available that let you view acquisition and
reference memories separately, or in comparison. When viewed in
comparison, the two memories are displayed side by side and any
differences between them are highlighted.

HISTOGRAM OVERVIEW DISPLAYS
A special feature of the state analyzer is its Histogram Menu.

In this menu, you can perform range-activity measurements
of acquired data.
The Histogram Menu works in the following way. You define
up to 16 address or data ranges for a specific channel group. The
state analyzer then calculates and graphically displays the percentage
of acquired data that falls into each range.
Additional functions are provided that allow you make continuous acquisitions while in this menu. This way, you can dynamically monitor the system under test and observe any shifts in activity
levels.

STATE AND TIMING TOGETHER MODES

If you have both the Interactive State Analyzer and the Model
2200 Interactive Timing Analyzer installed in your ,Analyst. you can
use them together in time-aligned acquisition modes. The pAnalyst
provides a full range of cross-arming and cross-triggering capabilities.
Refer to Section 6, State and Timing Together, for a detailed
discussion of how to use these two analyzers together.

MENU STYLE

In Northwest Instrument Systems' products the word menu
takes on extended meaning. The following paragraphs introduce you
to our way of implementing menus.
What are Menus?

Traditionally, menu has referred to a simple, one-dimensional
list of function or command options. This is also true for the Interactive State Analyzer, but menu also refers to a more visual, twodimensional method of displaying selectable or programmable items.
Fields within a menu may have multiple choices associated with
them.
The command line is a list of directives or operations that
appears at the bottom of the screen. Typically, these commands
move the system from one menu to another, or initiate specific actions
within the system or the menu currently displayed.
When you are in the edit mode, the edit prompt line appears
in place of the command line. This line indicates the acceptable edit
choices for a specific field. The following subsections will have more
details about the command and edit modes.
Command and Edit Modes

In the following pages and in using the state analyzer itself,
you will notice several command options. One important item to
remember is that there are two distinct menu modes:
•

Edit-to set up or change a programmable field within a
menu, you must be in the edit mode.

•

Command-to run the analyzer as programmed, you must
be in the command mode. Other functions of this mode
include viewing collected data, using various tools to analyze
the data, storing the collected data, and so on.
Visual and Audio Cues

The state analyzer keeps you informed of what it is doing
through several reserved lines at the bottom of the screen.
I

At the bottom of the screen is the command line. This line
shows what commands are currently available. Mnemonic key assignments are used wherever possible in this line. For example, you
would press E to enter the edit mode, G to go, M to list the menus
available, and so on. Keep an eye on this line; the scope of available
commands can change from mode to mode and menu to menu.

The next line up from the bottom displays errors, warnings,
and other messages. Appearance of text on this line is accompanied
by some audible signal. A short clicking sound indicates that additional information has been displayed. A beep indicates a warning, a
potential error condition, or an error condition. When you hear a click
or beep, refer to this line.

Menu Flow and Hierarchy
Figure 5-1 shows the basic structure of the state analyzer
menus.
Note that once you are in the Format Menu you can freely
jump from menu to menu. (The bold line to the Format Menu indicates the first-time path taken from the Configuration Menu.)
You enter a menu by pressing M for Menus from the command, then by pressing the first letter of the menu name. For example, T for Trigger-Store. You enter an environment submenu by
pressing V for enVironment from the command line, then by pressing
the first letter of the submenu name.

Programming Fields Within Menus
As you will see later on, there are a lot of things that you can
program in any menu to make the analyzer perform as needed.
Some basic conventions have been followed throughout the state
analyzer system.
1. To change a programmable field, you must be in the edit
mode. You can only enter the edit mode when the Edit command appears on the command line at the bottom of the
screen.
2. Pressing the escape key exits the edit mode and returns you
to the command mode.
3. Once you are in the edit mode, fields that appear in reverse
video are programmable. The field that can be modified will
blink.
4. Many of the fields are programmed by making selections
from a predetermined list of options. When prompted by the
edit prompt line "SPACE scrolls through choices," all you
need to do is press the space bar to view and select the
options.

5 Format Menu . . . . . . . . . . . . . . . . . . . . . ..
MODEL 2100

OVERVIEW

The Format Menu allows you to set up acquisition parameters
for the system under test and to format acquired data.
In this menu, you define the state analyzer's flexible clocking
scheme. Five sample clocks are ORed to make up the master clock.
Two hold clocks allow you to delay, or stretch, data until a valid sample clock samples the data. A combination of sample and hold clocking and the multiplexed data acquisition mode enable you to capture
data from multiplexed systems.
For the clock probe, you can set the polarity of the run/stop
line. For the data probes, you can specify multiplexed or nonmultiplexed data acquisition.
To make the Symbol and Display Menus easier to interpret,
you can assign labels to channel groups, specify their appropriate
radix and polarity, and predetermine their display order. This subsection explains how you use the Format Menu to perform all of these
activities.

MENU FIELD SELECTIONS

Figure 5-4 illustrates a typical Format Menu display. You enter
this menu by pressing M for Menu, then F for Format from the command line.
Use the numbered callouts in Figure 5-4 as a reference while
reading the following field descriptions. To make any changes to a
field, you must be in edit mode (press E for Edit), and you must have
the screen cursor positioned in the field.

and it will be automatically stored with any menu setups or memories
in the 1/0 Menu.

The default name in this field is ISA 2100. You can change
this to any other name using up to eight characters. A useful name
might be the name of the microprocessor or test procedure you are
working with, such as 8086_SYS or MEMCHECK.

Sample Clock Slope

These fields are used to establish the synchronous, master
sampling clock. The five sample lines, labeled S1-85, are provided
via the clock probe attached to the state analyzer's controller board.
Each line provides a maximum sampling rate of 10 MHz.
You can use one or all of these sample lines to define the
master clock. The lines work together in an ORed condition.

Using the space bar, you can set the polarity of any sample
line to:

•

+ (positive polarity)-data is sampled on the signal's rising
edge.

•

- (negative polarity)-data is sampled on the signal's falling
edge.

•

OFF-the sample line is not used.

[B" NOTE
If you turn a sample line off, make sure that the line is physically disconnected from any signal source. Otherwise, it may cause interference with the other sample lines.

Positive vs Negative Clock Polarity. Figure 5-5 illustrates
the difference between positive and negative clock polarity.
When positive polarity is selected for a clock, the data is
sampled on the clock's rising edge, and the pulse width for the clock
is defined from falling edge to rising edge. When negative polarity is
selected for a clock, the data is sampled on the clock's falling edge,
and the pulse width for the clock is defined from rising edge to faIling edge.

the clock probe. Using the space bar, you can set the polarity of
either hold clock to:

•

+ (positive polarity)

•

Run/Stop
This field lets you program the polarity of the Run/Stop line.
The line is an open collector output from the clock probe, and it is
used to indicate to external hardware when the analyzer is running
(acquiring data) and when it is stopped.

Using the space bar, you can set the polarity of the
Run/Stop line to:
•

HI/LO-the line is high when the analyzer is running and low
when it is stopped.

•

LO/HI-the line is low when the analyzer is running and high
when it is stopped.

J-tSlot (Probe Identifiers)

This menu column is not a programmable field. Rather, it
serves as a probe identifier for the M UX, Hold Clock, and Channel/Group Assignment fields (see callout numbers 6, 7, and 8).
In this column, each probe is identified by its slot number.
An L indicates the lower probe on a 32-Channel Memory Board,
while a U indicates the upper probe. A 16-Channel Memory Board
has only one probe, so there is not an L or U designation.

MUX (Multiplex)

These fields allow you to establish multiplexed or nonmultiplexed acquisition for each data probe.
Using the space bar, you can set each probe to:
•

YES-the probe acquires multiplexed data.

•

NO -the probe does not acquire multiplexed data.
When you first attempt to set a probe's MUX field to YES,
the J-tAnalyst will prompt you with the following message:
"Change channel assignments to keep groups contiguous? (yIN!?)"

This message is a reminder that when a probe is set to multiplexed acquisition, its eight most significant channels are ignored
and removed from any channel groups. The multiplexed data is
acquired in two phases on the eight least significant channels.

Hold Clock

These fields are used to assign the hold clocks, H1 or H2, to
specific data probes.
The characteristics of the two hold clocks are determined by
the polarities set up in the Hold Clock Polarity fields (see callout number 3). Table 5-1 describes the various hold-clock selections, and
explains when they are available for use.
When acquiring non-multiplexed data, you can program the
probe's Hold Clock field to any of the available selections listed in
Table 5-1.
When acquiring multiplexed data, you can program the Hold
Clock field for the first data byte to any available selection, but you
cannot program the Hold Clock field for the second data byte. As

Channel/Group Assignments

These fields let you organize data channels into meaningful
display groups. Seven groups, labeled A-G, are available for use.
Each group can contain up to 32 channels.
To assign a channel to a group, simply enter the group letter
into the channel's field. To set a channel to don't care, enter an X.
All channels within a given group must be contiguous; that
is, they must be linked from least significant bit (Isb) to most significant bit (msb). The following paragraphs explain how to determine
the bit significance for both non-multiplexed and multiplexed
channels.
Bit Significance of Non-Multiplexed Channels. With nonmultiplexed channels, the least significant bit (Isb) is the lowest numbered channel of the lowest numbered probe. The most significant

These fields are used to assign names, logic polarities, and
radices to your channel groups.
Enter a group name using up to eight characters. Useful
names might be ADDRESS, DATA, STATUS, CONTROL, etc.
Select a group's polarity using the space bar. Choices
include: positive (+) or negative (-). If positive polarity is selected,
the Display Menu will show data above the probe threshold as high

is selected, the Display Menu will show data above the probe threshold as low (0), and data below the probe threshold as high (1).
[B'" NOTE
The Trigger-Store Menu automatically adjusts its word recognizers to
match the selected polarity.

Select a group's radix by using the space bar. Choices
include: HEX (hexadecimal), OCT (octal), BIN (binary), or ASC
(ASCII). If ASCII is selected, only the seven least significant bits of

OVERVIEW

The Symbol Menu enables you to program values associated
with the names you've assigned to channel groups in the Format
Menu. Once the values are assigned, the symbols can be used in
the Trigger-Store Menu and the Display Environment Submenu as
identifiers for word recognizers and find words. This means you can
refer to user-created events by name throughout the menu setups,
making them easier to read and understand.
When working in the Symbol Menu, you may enter the symbol name, enter the value you wish to assign to the name, insert a
line to add a new symbol to an already filled-in table, or delete a line
that is in error or is no longer needed.
A sym bol table is created in one of two ways. You can create
symbols in the Trigger-Store Menu, and then go back and enter their
values into the Symbol Menu. (This is the more usual approach,
because it's easier.) Or you can first create symbols and values in the
Symbol Menu, and then enter the symbols by name in the TriggerStore Menu as part of the triggering and qualification conditions. You
can also buffer data from the Display Menu and use it to assign a
value to a symbol.
This subsection shows you how to use the Symbol Menu to
enter new symbols or modify existing symbols.

[B' NOTE

If you try to delete a symbol name that is currently being used by a

Y for Yes. Menus that use symbols include the Trigger-Store and
Histogram Menus, and the Display Environment Submenu.

® Data Values
These fields are used for assigning data values to the symbol
names.
[B' NOTE

An alternate procedure for entering symbol values is discussed
under callout number 4, un Buffer.

The column headings above the data value fields correspond
to the channel groups and radices assigned in the Format Menu.
When entering values, you must use the appropriate radix notation,
as defined below:
•

HEX-Enter 0 through F, or enter X for don't care.

•

OCT-Enter 0 through 7, or enter X for don't care.

•

BIN-Enter 0 or 1, or enter X for don't care.

•

ASC-Enter an ASCII character or control character (see
Appendix A at the back of this manual).

A special condition may arise when you are entering a value.
The first digit entry may have fewer legal values than what is usually
available under the radix. This occurs when the number of channels
assigned to the group is fewer than what is expected by the radix.
For example, a group may have six channels and a hexadecimal radix. This would mean that the first character in the group
can only have a value of 0 through 3, or X.
If such a condition should arise, the message line at the bottom of the screen will prompt you accordingly.

MODEL 2100

® unBuffer
As an alternative to typing in data values, you can use this
command to transfer a data value directly from a line in the state
display.
To use this command, you must first go to the Display Menu
and enter one of the display lines into the buffer (see the Display
Menu later in this section).
Once you have buffered a line, return to the Symbol Menu.
Position the screen cursor in the Name field of the symbol you want
to receive the buffered value. Then, press Control-B ( A B) for
unBuffer.
The buffer can only hold one line, so if you wish to make
several entries this way, you must return to the Display Menu after
one unbuffering operation, place another value in the buffer, go back
to the Symbol Menu, and enter the next buffered value.

o Toggle Mask
The Control-T ( 1\ T) Toggle Mask command lets you set
individual masked bits without changing their radix to binary. The
command toggles between masked and non-masked values. With
masked values, the symbol value and mask are split into two lines,
and with non-masked values they are merged.
Each symbol may be thought of as containing two words.
The first word is the value of the symbol, and the second word, or
mask word, represents which channels are considered as part of the
value (cares) and which are not (don't cares). Care bits are
represented by 1 and don't care bits by O.
It is usually convenient to define a symbol as having a
specific value in a manageable radix. For example, suppose you
were looking for modifications made to hexadecimal addresses in the
range 08 to OF. It's much easier to deal with 08 than with its binary
representation 11011000. In binary radix, you could define a word to
cover the hexadecimal range 08 to OF as 11011 XXX. Then in hexadecimal you could define the symbol for the address 08 and assign
a mask value F8. The lower three bits are treated as don't cares, but
the readability and sense of address 08 are preserved.
For non-masked symbols, enter X into a character position to
define the don't care. Depending on the radix of the character position, the don't care may apply to one or more bits. For example, an
X entered into a hexadecimal character sets all four bits of the

OVERVIEW

The Trigger-Store Menu is used to determine which data is
stored in memory, and when. You can set up as many as 15 trigger
states, with four states displayed on the screen at one time. These
states can be used independently, or they can be combined in any
sequential or branching order.
Within each state, you can specify one or two word recognizers for defining IF-THEN-ELSE triggering conditions, and you can
specify one or two word recognizers for defining storage qualification.
You can also assert the Real.:rime Programmable Outputs (RPOs) and
Crosslink (CL) output for interaction with the system under test.
In the rest of this subsection, you'll find detailed information
on how to use the Trigger-Store Menu to set up the various triggering
and storage qualifier conditions.

IB' NOTE
In portions of this subsection, reference is made to parameters
established within the Trigger-Store Environment Submenu. We will
discuss these parameters and show how they are used in the next
su bsection.

MENU FIELD SELECTIONS

Figure 5-9 illustrates a typical Trigger-Store Menu display. You
enter this menu by pressing M for Menu, then T for Trigger-Store
from the command line.
Use the numbered callouts in Figure 5-9 as a reference while
reading the following field descriptions. To change a menu field, you
must be in the edit mode (press E for Edit), and you must have the
screen cursor positioned in the field.
If the pAnalyst's HELP DISK is installed, you can use the
?=Help function to obtain information about a specific field. To do
this, enter the edit mode, then position the screen cursor in the
desired field and press the? (question mark) key.

Trigger Position

This field is used to position the trigger in acquisition memory. Using the space bar, you can select:
•

BEGIN-the trigger is delayed by 4082 words.

•

CENTER-the trigger is delayed by 2047 words.

•

END-the trigger is delayed by 13 words.

•

DELAY < 0-4096 > -the trigger is delayed by the specified
number of words.

The total acquisition memory depth is 4096 words. Data
acquired before the trigger is called pre-trigger data, and data
acquired after the trigger is called post-trigger data.
The amount of pre-trigger data acquired in memory depends
on how quickly the trigger occurs. The state analyzer looks for a trigger immediately; it does not wait until memory is full.

. . . . . . . . . . . . . . . . . . . 5 Trigger-Store Menu
MODEL 2100

IE NOTE
When the state analyzer is operating in the MultiplePreview Acquisition (MPA) mode, the only trigger position available is DELAY
<0-4096>. (Refer to the Trigger Environment Submenu contained
later in this section.)

State
This field is used to name, insert, or delete trigger states.
Altogether, there are 15 trigger states available for use. Each state
provides two word recognizers for establishing trigger conditions,
and two word recognizers for establishing storage qualification.
To insert a state, move the screen cursor to a current State
field, then press the insert key. The current State field will move
down one position on the screen, and a new, blank State field will
appear at the cursor location.

IE NOTE
You can also create a new state by entering the name of the state
into one of the GOTO fields (see callout number 3).

To name a state, enter up to five characters. To rename an
existing state, simply enter the new name over of the old one. The
p.Analyst will ask you to confirm the renaming by pressing Y for Yes
or N for No.

IE NOTE
When you rename a state, all references to that state (as in GOTO
trigger actions) will be automatically updated.

To delete a state, move the screen cursor to the State field
you want deleted. Then, press the delete key. The p.Analyst will
delete the state and its word recognizers.

IE NOTE
When you delete a state, all references to that state (as in GOTO
trigger actions) will default to the next sequential state. If there are
no next states, the references will default to their own state.

1st Word Recognizer
The 1st Word Recognizer can be used by itself, or it can be
combined with the 2nd Word Recognizer to form IF-THEN-ELSE triggering conditions. The possible options for the 1st Word Recognizer
are listed below.
A. IF (I) OCCURS (1-4096) TIMES THEN-> (GOTO
< state> or TRIGGER)

B. IF (I) OCCURS AFTER (1-4096) (SAMPLE or STORE)
CLOCKS THEN - > (GOTO < state> or TRIGGER)

MODEL 2100

C. IF (/) < symbol> OCCURS BEFORE (1-4096) (SAMPLE or
STORE) CLOCKS THEN -> (GOTO or TRIGGER)

As you can see, each word-recognizer option has several
programmable fields. The following paragraphs describe how you
make entries into these fields.
Logical True or Not True (I) Field. Use this field to specify
whether the symbol used in the word recognizer is set to its logical
true or not true value. Your choices include:
•

A blank field-the symbol is set to its true value and recognition will occur when the symbol value appears at the probe
tips.

•

/ (not)-the symbol is set to its not true value and recognition
will occur when any value other than the symbol value
appears at the probe tips.

Symbols. Use this field to enter the symbol you want to use
for word recognition. The value of the symbol is defined in the Symbol Menu.
To use a symbol that has already been defined in the Symbol
Menu, simply enter the symbol's name. If you can't remember all of
the available symbols and their names, you can use the Control-S
( 1\ S) key to scroll through the symbols: Each symbol and its value
will appear at the bottom of the screen under the heading "selected
symbol."
You can also enter a symbol that has not been defined in the
Symbol Menu. To do this, simply enter any name using up to eight
characters. The pAnalyst will then ask if you want to add the name to
the Symbol Menu. Press Y for yes.
When you are finished with the Trigger-Store Menu, you will
need to return to the Symbol Menu and enter the values for any new
symbol names you have created.
Occurrence Counter (1-4096). Use this field to set up the
word-recognizer counter. Depending on the word-recognition option
you've selected, the field may serve as an occurrence counter or a
time window. Valid entries into the field include 1-4096, inclusive.
The counter can be set to count SAMPLE or STORE clocks.
Sample clocks are defined by the master sample clock. Store clocks,
on the other hand, are not physical clocks. Rather, they are defined
by the words you have asked the analyzer to store (see Storage
Qualifiers, callout number 4).

When you set a word recognizer to GOTO, you must also
enter the name of a state. The name can belong to an existing state,
or it can be a new one. If you enter a new name, the pAnalyst will
ask if you want to insert a new state. Press Y for yes. Then go to the
newly entered state and define it.
[B'" NOTE
If you have already defined 15 states, the pAnalyst will not allow you
to insert a new state from the GOTO field. Instead, a message will
appear reading "no new states are available; must use an existing
state name."

2nd Word Recognizer

The 2nd Word Recognizer can be used in conjunction with
the 1st Word Recognizer. It allows you to set up the IF-THEN-ELSE
triggering conditions outlined below.
A. IF (I) OCCURS (1-4096) TIMES THEN -> (GOTO
< state> or TRIGGER)
ELSEIF (/) OCCURS ANYTIME THEN -> (GOTO
< state> or TRIGGER
B. IF (/) OCCURS AFTER (1-4096) (SAMPLE or STORE)

D. IF (I) OCCURS BEFORE (1-4096) (SAMPLE or
STORE) CLOCKS THEN - > (GOTO < state> or TRIGGER)
ELSE

As you can see, the various word-recognizer options have
several programmable fields, including: Logical True and Not True
(I), Symbols, and GOTO or TRIGGER actions. You program these
fields as specified under 1st Word Recognizer, callout number 3.

Options A and B have no additional programmable fields.
Options B, C, and 0 have programmable Logical True and Not True

under 1st Word Recognizer, callout number 3.

RPO and CL Outputs
These fields let you assert the Real-Time Programmable Outputs (RPOs) and Crosslink (CL) signals.
Real-Time Programmable Outputs (RPOs). The RPOs are
two output lines provided via the state analyzer's clock probe. The
lines are labeled RP01 and RP02.
Using the space bar, you can set the RPOs to two bits
encoded as 0, 1, 2, or 3. The encoding works as shown in Table
5-2. A zero (0) corresponds to a low-level (open collector, actively
pulled down) output and a one (1) corresponds to a high-level (open
collector, resistively pulled up) output.

The RPO values are output to the clock probe when a transition from the current state to the next state occurs. Thus, while data
is being acquired in a particular state, the RPO lines are set according to the value in the previous state.
[B" NOTE

The starting values of the RPOs are programmed via the TriggerStore Environment Submenu.

Crosslink (CL). The Crosslink signal is output through the
CL BNC connector located on the back of the pAnalyst mainframe. It
is also output internally on the pAnalyst's interconnect bus, and it can
be used for crosslink triggering between the state analyzer and other
pAnalyst products, such as the Interactive Timing Analyzer.
Using the space bar, you can program the Crosslink to output a 0 (active low) or a 1 (open collector high). The Crosslink value
is output when a transition from the current state to the next state
occurs.

SPECIAL COMMAND-LINE FUNCTIONS

As shown in Figure 5-10, the Trigger-Store Menu provides an
additional command-line function that is not available in other menus.
This command, labeled Sc roll states, lets you scroll backward
or forward through the defined trigger-store states. To use this command, press S. The display will scroll in the direction indicated by the
pointer « or » at the front of the command line. To change the
direction of the pointer to <, press the < (less than) or - (minus)
key. To change the direction of the pointer to >, press the > (greater
than) or + (plus) key.
You can also scroll through the trigger-store states by pressing the up and down cursor keys.

5 Trigger-Store Environment Submenu . . . . .
MODEL 2100

OVERVIEW

The Trigger-Store Environment Submenu allows you to define
several supporting trigger parameters. While these parameters are
readily accessible, they have been placed in a submenu so that their
meanings are not obscured, and so that the main Trigger-Store Menu
is not cluttered.
In this submenu, you can set up Multiple-Preview Acquisition
to enhance the trigger's storage qualifier functions. You can specify
whether the analyzer automatically stores all state transitions (i .e., the
events which cause the analyzer to move from one state to another).
Plus, you can establish starting values for the trigger states and the
Real-Time Programmable Outputs (RPOs).
In the rest of this subsection, you'll find detailed information
about how to use this submenu and its features.

SUBMENU FIELD SELECTIONS

The Trigger-Store Environment Submenu is called to the
screen by pressing V for enVironment, then T for Trigger-Store. It can
be called from any state analyzer menu. When it is called, the submenu temporarily covers the lower half of the screen.
Figure 5-11 illustrates how the submenu appears when it is
called from the Trigger-Store Menu. The submenu is automatically in
edit mode; it has no command line. You exit the submenu by pressing the escape key.
Use the numbered call outs in Figure 5-11 as a reference
while reading the following field descriptions.

CD Multiple-Preview Acquisition
This field is used to establish Multiple-Preview Acquisition.
Using the space bar, you can select:
•

NO-Multiple-Preview Acquisition is turned off .

•

YES-Multiple-Preview Acquisition is turned on.

When Multiple-Preview Acquisition is turned off, the state
analyzer acquires data as specified in the Trigger-Store Menu. It
stores events only if they match the specified storage qualifiers and
trigger conditions.
When Multiple-Preview Acquisition is turned on, the state
analyzer still acquires data as specified in the Trigger-Store Menu,
but it also acquires up to seven unqualified events immediately
preceding each qualified event. This way, you see a small window of
data leading up to the events you are interested in.

IB" NOTE
A detailed application example of how to use Multiple-Preview
Acquisition is provided in Section 7 of this manual.

5·37

5 Trigger-Store Environment Submenu . . . . .
MODEL 2100

® Store All State Transitions
This field lets you specify whether or not the state analyzer
acquires all events that cause state transitions (as defined by the
Trigger-Store Menu).
Using the space bar, you can select:
•

NO-the state analyzer does not automatically acquire events
that cause trigger state transitions. It only acquires the events
if they match the specified storage qualifier conditions .

•

YES-the state analyzer does automatically acquire all events
that cause trigger state transitions, regardless of whether or
not the events match the specified storage qualifier
conditions.

The usefulness of always storing state transitions becomes
apparent when you set up NEVER STORE storage qualifiers in the
Trigger-Store Menu.
For example, suppose you want to monitor several subroutine
accesses, but do not want to store all of the subroutine activity. You
could set up a state sequence that follows the paths of the subroutines and select NEVER STORE storage qualification. Storing all state
transitions would then allow you to verify that the subroutine accesses
occurred correctly, without scrolling through a lot of memory data.

® RPO Starting Value
This field is used to specify the starting values of the RealTime Programmable Output (RPO) signals.
Because the RPOs change at state transitions, you must
define their initial value-the value the RPOs are set to when the
state analyzer is started. Then, when the state analyzer leaves the
first state, theRPO values change to the value defined in the first
state.
In default, the RPOs start with a value of O. Using the space
bar, you can change this starting value to any value listed in Table 5-3 .

o Starting State
When you name the starting state in this field, the state
analyzer starts operating from any of the 15 defined trigger states.
For example, you could define several short trigger sequences to
perform individual tests and have all the sequences resident in the
state machine simultaneously. You would indicate which test to perform by selecting the state name of the beginning desired state as
the start state.
At the end of an acquisition cycle, one data acquisition
remains in the analyzer's pipeline. With a WARM start this data will
be treated as the first value of the next acquisition, and with a COLD
start it will be ignored.
All selections are made by using the space bar.

reference memory with acquisition memory and view any differences
in highlighted video.
The menu provides three basic state displays, including:
•

Acquisition Memory Display

Acquisition and Reference Memory Comparisons
The rest of this subsection discusses these displays and their
associated programmable fields. It also discusses the special
command-line functions that allow you to manipulate the memories
and their displays.
[B"" NOTE
Certain menu parameters, such as comparison limits, are set up via
the Display Environment Submenu. This submenu will be discussed
in the next subsection.

ACQUISITION MEMORY DISPLAY

Figure 5-12 illustrates a typical state display of acquisition
memory. You enter this display by pressing D for Display from the
command line.
The state display is formatted according to the specifications
you have entered in the Format Menu. The column headings reflect
the channel group names and their display order. The data is
presented in the chosen radix and polarity.
There are only two programmable fields in the Display Menu:
one programs the starting memory location for the top of the data
list, and the other lets you specify whether to display data from
acquisition memory, reference memory, or both.
Use the numbered callouts in Figure 5-12 while reading the
following field descriptions. To change a field value, you must be in
the edit mode (press E for Edit), and you must have the screen cursor positioned in the field.
If the HELP DISK is installed, you can use the ?=Help function to obtain information about a particular field. To do this, enter the
edit mode, then move the screen cursor to the desired field and
press the? (question mark) key.

top of the data list. The trigger position has a number value of o.
Words acquired before the trigger (pre-trigger data) have negative
number values, and words acquired after the trigger (post-trigger
data) have positive number values.
You can update the display to any portion of memory, by
entering the following values into the LOC field:
•

-9999 to + 9999-the display updates to the location number
specified, or to the location nearest that number. For example, if you specify -9999 and the lowest pre-trigger data location is -23, the display will update to location -23.

•

B-the display updates to the Beginning location in memory.

•

E-the display updates to the Ending location in memory.

•

T-the display updates to the Trigger's location in memory.

Once you have entered the location value, press the return
key to complete the entry.

• < -ACO REF- > -the display shows an acquisition and
reference memory comparison.
Figure 5-12 illustrates an ACO memory display. A REF memory display and an < -ACO REF- > memory comparison are illustrated in Figures 5-13 and 5-14, respectively.

REFERENCE MEMORY DISPLAY

Figure 5-13 illustrates a typical display of reference memory.
To enter this display, select the REF value in the Memory Selection
field.
[B' NOTE

To achieve a display similar to that shown in Figure 5-13, you must
first enter data into reference memory. To do this, use the
Ref < -acq command (see Special Command-Line Functions later
in this subsection).
The numbered call outs in Figure 5-13 illustrate the programmable fields within the reference memory display. Only the field numbered 3 is discussed here, since it is the only field different than
those provided in the acquisition memory display. For information on
how to manipulate fields numbered 1 and 2, refer back to the Acquisition Memory Display portion of this subsection.

SPECIAL COMMAND-LINE FUNCTIONS

In addition to the standard commands, the Display Menu provides several specialized commands that allow you manipulate the
display of data.
These commands do not all fit on the command line. To view

MODEL 2100

OVERVIEW

Through the Display Environment Submenu, you may specify
control parameters that will determine how data is acquired and displayed. These include:
•

Setting acquisition (Go) modes.

•

Setting the display mode to standard or compressed.

•

Setting up comparisons between acquisition and reference
memory, with options for range, offset, and mask.

•

Setting up the find function, and requesting either that all
states be included in the find pattern search or that the find
pattern occur in a specified state.

The rest of this subsection shows you how to set up and use
the above parameters, and explains the affects of these parameters
on the state display.

SUBMENU FIELD SELECTIONS

The Display Environment Submenu is called to the screen by
pressing V for enVironment, then D for Display from the command
line. It can be called from any state analyzer menu. When it is called,
the submenu temporarily covers the bottom half of the screen.
Figure 5-16 illustrates how the submenu appears when it is
called from the Display Menu. The submenu is automatically in edit
mode; it does not have a command line. You exit the submenu by
pressing the escape key.
Use the numbered call outs in Figure 5-16 as a reference
while reading the following field descriptions.

Acquisition Mode

This field establishes the state analyzer's acquisition (Go)
mode. Using the space bar, you can select:
•

GO ONCE- the analyzer acquires data until the trigger condition and delay count, if any, have been met.

•

GO FOREVER- the analyzer makes repetitive acquisitions,
using the starting state specified in the Trigger-Store Environment Submenu.

•

GO TIL ACO = REF-the analyzer makes repetitive acquisitions until the acquisition and reference memories are equal.

•

GO TIL ACO < > REF-the analyzer makes repetitive acquisitions until the acquisition and reference memories are
unequal.

When the state analyzer is running in the above modes, you
can stop acquisition in one of two ways. Press H (Halt) to stop the
analyzer immediately; or press S (Stop) to stop the analyzer after the
next trigger condition has been satisfied.

® Stop ACQ After Memory Overflow
This field is useful when you cannot specify an accurate or
appropriate trigger condition. It allows you to stop acquisition when
the analyzer detects a memory overflow condition.
Using the space bar, you can select:
•

NO-the analyzer does not check for a memory overflow
condition. Acquisition stops when a trigger has been generated and the post-trigger delay has been satisfied.

•

YES-the analyzer periodically checks for a memory overflow
condition. If an overflow has occurred, the analyzer will then
stop acquisition, regardless of whether or not a trigger has
been generated.

[B""NOTE
A YES value in this field does not prevent data from being overwritten in the state analyzer's memory; it just stops acquisition the first
time the analyzer detects that overwriting has occurred.

® Display Mode
This field is used to compress the state display. Using the
space bar, you can select:
•

STANDARD-data is displayed in the standard format.

•

COMPRESSED-data is displayed in the compressed format.

The compressed format packs more data onto the display by
shortening group names, removing spaces, and creating additional
columns of data display. In a system with a large number of channels or several groups with binary radix, it may not be possible to
display more than one column of data in compressed format.
Figure 5-17 illustrates an example of the compressed display
format.

Compare ACQ to REF

These fields control the acquisition and reference memory
comparisons. They specify display highlighting, comparison limits,
comparison offset, and masking.

Highlighting. You can turn display highlighting on and off
using the space bar. Your choices include:
•

NO-the highlighting is turned off.

•

YES-the highlighting is turned on.

When you select YES, any differences between acquisition
and reference data that are not masked by the compare mask symbol will be highlighted in the Display Menu.

FromlTo. The from and to parameters determine the range
of data locations for all comparisons between acquisition and reference memories. These boundaries are also used for the transfer of
acquisition data to reference memory.
The boundaries for the comparison can range from -9999 to
+9999.

MODEL 2100

IB' NOTE
If you are using the ~nalyst's 256K SYSTEM DISK, the size of reference memory may be limited. For details, refer to the front of this
manual and the page titled Software Versions Covered By This
Manual.

Offset. The offset parameter allows you to skew the reference data in relation to acquisition data. An offset of one or more will
move the data in reference memory down (or forward) on the Display
Menu. The offset parameter will be ignored during a transfer of
acquisition to reference memory.
A Mask.
The /\ Mask parameter is the name of a symbol
defined in the Symbol Menu. The mask part of the symbol specified
will be used as a mask during compare operations. These operations
include highlighting, GO TIL ACO = REF or GO TIL ACO < > REF
acquistion modes, and NexLDiff and Total_Diff commands.

A zero bit in the "Mask field means don't compare for that
channel.
Symbols are entered into the /\ Mask field by typing the
selected symbol's name. If you cannot remember all of the symbol
names within the Symbol Menu, you can use the Control-S ( A S) key
to scroll through the symbol names. Each symbol name and its value
appears on the bottom of the screen under the heading "selected
symboL"
Operational Notes. For all the compare functions, the STATE
group is ignored. When acquisition and reference data do not overlap, they are considered equal. For example, if the amount of reference data differs from the amount of acquired data, all data in
unmatched line numbers will be considered equal (subject, however,
to the offset parameter).

Find Pattern

This field establishes the find pattern used by the Display
Menu's Find command.
The find pattern may consist of from one to four words, with
each word specified by its name in the Symbol Menu. Note that the
mask part of each symbol may be used to ignore part of the symbol
during a find operation. A zero bit in the symbol's mask is a don't
compare for that channel.
Use the insert key to insert a word in the search pattern. Use
the delete key to delete a word in the search pattern.

5·52

• • • • • • 5 Display Environment Submenu
MODEL 2100

Each word in the search pattern has a corresponding state
field. This field lets you specify which trigger-store state the word
must be in to match the find pattern. For example, suppose you set
up the following conditions:
Find pattern Multiplex in state Mux

In this case, the Display Menu will compare the Multiplex pattern to all state samples that were acquired in the state Mux. Any
other state samples will be ignored.
You can select between the various trigger-store states by
using the space bar. If you leave the state field set to all blanks, the
find word will be compared to all trigger-store states.
If the find pattern consists of more than one word, each word
in the pattern may be separated by from 1 to 4096 locations. A value
of 1 means that the words must be found in consecutive locations
(i.e., there can be no other samples between them).
For example, suppose you set up the following conditions:
Find pattern
followed by
followed by

Multiplex
Non-Mux
LowReset

in state
in state
in state

Mux
Nomux
(blank)

within 01 locations
within 50 locations

When you execute the Find command, the Display Menu will
first look for the word Multiplex in state Mux. If this word is found, the
menu will then look at the next immediate memory location to see if it
contains the word Non-Mux in state Nomux.
If the next immediate location does not contain Non-Mux, the
menu will again look for Multiplex followed by Non-Mux, and so on. If
the next immediate location does contain Non-Mux, the menu will
look for LowReset in the next 50 locations.
If LowReset is found, the menu will update the display to that
location. If LowReset is not found, the menu will again search for
Multiplex, followed by Non-Mux, and so on.
The Display Menu will continue to search for the pattern
throughout the entire state memory. If the pattern cannot be found, a
message will appear on the display.

5 Histoaram Menu . . . . . . . . . . . . . . . . . . ..
~ODEL 2100

OVERVIEW

The Histogram Menu is used to perform range-activity analysis on acquired state data. This can include address activity or
specific data activity, optionally qualified by some value you select.
With this menu, you can define up to 16 ranges for a particular channel group. The system then calculates and displays the percentage of activity occurring within each range. You can view the
range activity levels in a proportional bar graph, or you can view an
occurrence count of the events falling into each range.
A defined range is called a bin, and the process of determining what data or address falls into a bin is called binning.
The rest of this subsection illustrates how you use the features of the Histogram Menu.

MENU FIELD SELECTIONS

Figure 5-18 illustrates a typical Histogram Menu display. To
enter this menu, press M for Menu, then H for Histogram from the
command line.
Use the numbered callouts in Figure 5-18 as a reference
while reading the following field descriptions. To change a menu field,
you must be in the edit mode (press E for Edit), and you must have
the screen cursor positioned in the field.
If the pAnalyst HELP DISK is installed, you can use the ?=Help function to obtain information about a particular field. To do this, enter the
edit mode, then move the screen cursor to the desired field and
press the? (question mark) key.

For Group
This field selects the channel group that is to be analyzed.
Only the data acquired from one channel group can be binned at
anyone time. The organization of channel groups is determined in
the Format Menu.
Note that as you scroll through the groups, the names originally assigned in the Format Menu appear in the reverse video field.
You cannot change groups names here, but you may go back to the
Format Menu and do so. If no group name was assigned in the Format Menu, the default group name ( A, B, C, etc.) appears in the
field. The single letter reference always appears parenthetically just
before the reverse video field.
Also note that the numerical range of the group, as determined by its assigned channels, is reflected in the From and Thru
fields (see menu callout number 5).

® Qualified By
This field lets you select a qualifier from the current list of
symbols in the Symbol Menu. All values will be binned if the selected
qualifier symbol is set to all don't cares (i.e., the Any Value symbol).
Alternately, you can selectively use don't cares to range the data or
look for a specific type of data.
For example, you might bin address information qualified by
memory reads. The qualifier symbol would select the control line pattern that indicates a memory read, and the group containing the
address bus information would be binned.
For more information on setting symbol values, refer to the
Symbol Menu.

Name
These fields are used for naming the ranges. You can enter
any name up to 10 characters. The names are for your reference
only and do not affect the binning process. The up and down cursor
keys select which line to edit.

From-Thru
These fields establish the inclusive beginning and ending
limits for the ranges. Ranges may overlap, but the data will fall into
the first bin that satisfies the range specification. Data will not be
duplicated in any subsequent bins, even though another bin may
satisfy the range requirements. The up and down cursor keys select
which line to edit.
~NOTE

To specify a range of one value, enter the same value into the From
and Thru fields.

Other (Outside Ranges)
This field is used to include or exclude data that does not fall
within any of the specified ranges. Using the space bar, you can
select:
•

OTHER-bin the data falling outside the ranges in this group .

•

A blank field-ignore the data falling outside the ranges.

When OTHER is selected and its contents are greater than
zero, percentages of the other ranges may change.

OPERATIONAL NOTES

Trigger-Store Setups for Range-Activity Measurements.
When you are acquiring data for a range-activity measurement, try to
capture as broad a sampling as possible. The more code sampled
during a given acquisition, the better the statistical distribution.
One way to optimize the state analyzer's sampling capability
is to set up a storage qualification loop that captures a selection of
the executing code rather than every cycle.
For example, you could set up the following storage loop in
the Trigger-Store Menu:
<1> IF OCCURS AFTER 0050 SAMPLE CLOCKS THEN
-> GOTO <2>
NEVER
> STORE
<2> IF OCCURS 0001 TIMES THEN--> GOTO <1 >
ALWAYS
> STORE

This storage loop stores one out of every 51 cycles. The state
analyzer is able to monitor a much broader range of code before binning the data into the histogram ranges.
Notice that the above storage loop does not establish a trigger condition. To stop acquisition in this case, use the Stop ACO After
Memory Overflow option in the Display Environment Submenu.
Printing the Histogram Display. The bins must be cleared
before binning a new group. You will be prompted if you attempt to
change bin groups without first clearing the bins. If you do not wish
to clear the bins, press N for No when the prompt appears. If you
wish to clear the bins, enter Y for Yes.
Before clearing the bins, you may wish to first print the display using the PrtSc (PrintScreen) key. Bin names and range values
can be saved on disk as part of a setup file in the 1/0 menu, but the
binned data cannot be saved.

SPECIAL COMMAND-LINE FUNCTIONS

In addition to the standard command functions, the Histogram Menu provides specialized commands that allow you to control
the binning process.
These commands do not all fit on the command line. To view
the entire list of commands use the space bar.
The following paragraphs describe the commands in the
order they appear on the command line. The bold, capitalized letter
in each command indicates the letter key you must press to activate
the command.
Go

This command starts the acquisition and automatically bins acquisition memory for the range and
group specified. This can be most useful when one
of the continuous Go modes is used (as specified in
the Display Environment Submenu). Repeated acquisitions are made, thus increasing the number of
observations.
Go with automatic binning only occurs when G is
pressed while the Histogram Menu is on the screen.

bin-Acq

This command bins the data from acquisition memory. If data was previously binned and the bins were
not cleared, the results of the new binning are added
to the old bin data.
This command bins the data from reference memory.
If data was previously binned and the bins were not
cleared, the results of the new binning are added to
the old bin data.
This command clears the bins.

OVERVIEW

The I/O Menu lets you save menu setups and data. You can
load the setups and data onto disk for mass storage, or you can output them to an IBM-compatible printer.
Setups and data stored on disk can be recalled and loaded
into the state analyzer at any time. Setup files contain information
from the Format, Symbol, Trigger-Store, and Histogram Menus, and
from the Trigger-Store and Display Environment Submenus. Data files
contain the data contents from reference memory.
Using the menu's printer function, you can also make hard
copies of the Symbol, Trigger-Store, and Display Menus. You can
send these menus to a printer or save them on disk for later output
to a printer. The rest of this subsection shows how to use the I/O
Menu and its disk-storage and printer capabilities.

MENU FIELD SELECTIONS FOR DISK

Figure 5-20 ill.ustrates the I/O Menu when DISK is the

where < d >: is a drive location. If you do not want to
change drives, leave out the < d >: designation and just enter the
directories. The state analyzer will search for the directories in the
current drive.
When a new drive or directory is entered into the Path field,
the menu's directory window is automatically updated to show the
state analyzer files located at that directory level (see callout number
5). The window will not show any DOS system files or user programs.

File Name

This field specifies which file will be used during the I/O function. For SAVE functions, enter a new file name. For LOAD or
DELETE functions, enter the name of a file that already exists in the
current directory.
A file name can be up to eight characters in length. Certain
characters cannot be used in the name, such as dashes, commas,
dollar signs, and others. The message line at the bottom of the menu
will advise you when an illegal character has been entered.

Function

This field specifies the 1/0 function to be performed on the
selected file. Using the space bar, you can specify one of the functions listed below:
•
•

SAVE-saves the file on disk.
LOAD-loads the file into the state analyzer.

•

DELETE-deletes the file from disk.
The following paragraphs describe each of these functions.
You execute a given function by pressing X for eXecute from the
command line. (Refer to Special Command-Line Functions later in
this subsection.)
SAVE Function. This function lets you save a new file on
disk. The new file is identified by three elements: a file name, a file
type, and a description.
[B'"' NOTE

The disk used for storing the new file must be formatted for DOS
(version 2.00 or higher). For procedures on how to format a diskette

pressing Y for Yes.
The file type is specified in the field which appears next to
the SAVE field. Using the space bar, you can select:
•

SETUP-which saves menu setup information.

•

DATA-which saves the data from reference memory. (Data
from acquisition memory cannot be transferred directly onto
disk. To save acquisition memory, you must first transfer it to
reference memory.)

[B'" NOTE

The byte structure used for DATA files is provided in Appendix B at
the back of this manual.

•

ALL-which saves both the menu setups and the data from
reference memory. This selection creates two files with the
same name, one for setup and one for data.

The file description is entered into the field that appears
below the Function field. You can enter up to 135 characters. The
description is saved with the file, and it will reappear on the screen
whenever the file is loaded into the state analyzer.

LOAD Function. This function is the reverse of SAVE. It lets
you load a file into the state analyzer. The file is identified by its name
and type.
When you load a file, the current analyzer setup and/or reference memory will be overwritten by the file. The pAnalyst will ask you
to confirm the action by pressing Y for Yes.
DELETE Function. This function is used to delete a file. The
file is identified by its name and type.
When deleting a file, the pAnalyst will first display a description of the file, then it will ask you to confirm the action by pressing Y
for Yes.
Directory Window
The directory window lists the state analyzer files that are
located at the current drive-directory level.

OVERVIEW

You can use the Interactive State Analyzer in conjunction with
the Interactive Timing Analyzer if you have both products installed in
the pAnalyst 2000 Mainframe. Many combinations of aligned and
non-aligned acquisition modes are available for operating the two
analyzers together.
Aligned acquisition means that common time reference information is stored with the state and timing data as it is placed in
acquisition memory. This allows the synchronous data from the state
analyzer to be correlated with the asynchronous data from the timing
analyzer, and vice versa.
The correlated state and timing data is shown in a splitscreen display. You can view of the same point in time from the different perspectives of the state and timing analyzers. Dual scrolling
allows you to move between the analyzer memories simultaneously.
When you scroll the state or timing window, the other window keeps
in step.
The time correlation between state and timing data is handled internally by the pAnalyst. Post-acquisition software matches the
state clocks to the timing acquisition data and uses the Crosslink (CL)
signal as a common reference point.
Non-aligned acquisition means that the Crosslink (CL) signal
is used in a more general way. Because the acquisitions are not timealigned for display, more programming flexibility is allowed than in
one of the aligned modes.
The options for operating the state and timing analyzers
together allow for the state analyzer to arm the timing analyzer, and
vice versa.
It is important to note the difference between triggering and
arming. Triggering occurs when an incoming sample satisfies the programmed trigger condition. Arming an analyzer does not mean that
the analyzer has been triggered, it only means that the analyzer has
been enabled to look for its trigger. When the analyzer is not armed,
the trigger condition may occur, but the analyzer will ignore it.
The Crosslink (CL) is an internal bus line that is used to communicate the arm/not-armed condition. The CL can be used in either
direction-state arms timing or timing arms state. (The signal on the
CL line also appears as an output at the CL BNC connector located
on the mainframe's back panel).

ALIGNED/NON-ALIGNED MODES

You select the aligned/non-aligned acquisition modes in the
Configuration Menu. As shown in Figure 6-1, a special operating
option, titled State & Timing Analyzers, is provided when both
analyzers are installed in the pAnalyst mainframe.
To select the State & Timing Analyzers option, move the
screen pointer to that option's location, then press the return key. The
Configuration Menu will immediately display the aligned/non-aligned

• Figure 6-2. Aligned/non-aligned acquisition modes.

The following paragraphs describe the various aligned/nonaligned acquisition modes. Note that the mode descriptions appear
in a different order than the modes appear on the screen. This is
because the two aligned modes (State Arms Timing and Timing Arms
State) contain background information that will be needed for the
non-aligned mode (Crosslink Triggering).

State Arms Timing (Aligned)
In this mode, the state analyzer looks for an occurrence or
sequence of occurrences before arming the timing analyzer. The
Crosslink (CL) line is used to provide the arming signal. The word
recognizers and triggering sequences in the state analyzer must be
programmed so that CL will go low (0) when you want the timing
analyzer to be armed.
Once arming occurs, the timing analyzer will be able to look
for its own trigger pattern. If the timing analyzer's trigger pattern has
been to set to all don't cares (Xs) , it will trigger immediately.

6 State & Timing Together . . . . . . . . . . . . . ..
MODEL 2100

There are some programming requirements in the State Arms
Timing mode that must be followed. The requirements are listed
below.
State Analyzer Programming Requirements, Aligned Mode,
State Arms Timing (for information about the specific menus mentioned, see Section 5 of this manual):
1. Once the state analyzer asserts CL=O in a trigger-store state,
all of the following states must also assert CL=O. This way,
CL remains asserted throughout the duration of the timing
analyzer's acquisition.
2. All acquisition clocks must be stored, therefore:
a. The Multiple-Preview Acquisition (MPA) mode is not available in the Trigger-Store Environment Submenu.
b. The Store All State Transitions field must be set to YES in
the Trigger-Store Environment Submenu.
c. The storage qualifiers must all be set to ALWAYS STORE
in the Trigger-Store Menu.
3. Only 14 programmable states are allowed in the Trigger-Store
Menu. The fifteenth state is allocated for internal use.
Timing Analyzer Programming Requirements, Aligned
Mode, State Arms Timing (for information about the specific menus
mentioned, refer to the Interactive Timing Analyzer Users ManuaD:
1. The Multi-Triggers mode is not available in the Format Menu.
2. The timebase selection in the Format Menu is limited to 10 or
20 ns. This guarantees storage of the state analyzer's master
clock pulse.
If the programming requirements for the state and timing
analyzers have not been met, you will be prompted when attempting
to leave the edit mode. You can let the system correct the programming automatically, or you can enter the menus and correct the
programming manually, using the displayed error message as a
guide.
Time-Aligned Display Requirements. In addition to the
programming requirements listed earlier, there are certain conditions
that must be met before data can be correlated for display:
1. The state and timing memories must both contain the sample
event that caused the CL=O assertion.
2. The data in the state and timing memories must overlap at
some point in time (i.e., their time domains must intersect).

6·6

. . . . . . . . . . . . . . . 6 State & Timina Together
MODEL 2100

Position the state and timing triggers carefully to ensure that
the above two conditions are met. Only the state and timing data that
overlaps is correlated for display.
Timing Arms State (Aligned)
In this mode, an arming signal is generated when the timing
analyzer's trigger condition is met. The Crosslink (CL) line is asserted
low (0) and held until both the state and timing acquisitions are
complete.
On the state analyzer side of this mode, the CL is monitored
by a preprogrammed state. This state is internally programmed to
look for CL going low. (This internally programmed state will not be
seen in the state analyzer's Trigger-Store Menu.)
Once the CL is asserted, the state analyzer goes to the start
state you programmed in the Trigger-Store Environment Submenu. If
this start state is programmed to trigger on all don't cares, the state
analyzer will trigger immediately. Otherwise, it will execute the state
sequences as programmed.
As with the State Arms Timing mode, there are some
programming requirements in the Timing Arms State mode that must
be followed. These requirements are listed below.
State Analyzer Programming Requirements, Aligned Mode,
Timing Arms State (for information about the specific menus mentioned, see Section 5 of this manual):
1. All the states defined in the Trigger-Store Menu must be set
to CL=1. In order for the Timing Arms State mode to work
properly, only the timing analyzer can be allowed to assert
CL=O.
2. All acquisition clocks must be stored, therefore:
a. The Multiple-Preview Acquisition (MPA) mode is not available in the Trigger-Store Environment Submenu.
b. The Store All State Transitions field must be set to YES in
the Trigger-Store Environment Submenu.
c. The storage qualifiers must all be set to ALWAYS STORE
in the Trigger-Store Menu.
3. Only 14 programmable states are allowed in the Trigger-Store
Menu. The fifteenth state is used internally to look for the
arming signal from the timing analyzer.

MODEL 2100

Timing Analyzer Programming Requirements, Aligned
Mode, Timing Arms State (for information about the specific menus
mentioned, refer to the Interactive Timing Analyzer Users ManuaD:
1. The Multi-Triggers Mode is not available in the Format Menu.
2. The timebase selection in the Format Menu is limited to 10 or
20 ns. This guarantees storage of the state analyzer's master
clock pulse.
If the programming requirements for the state and timing
analyzers have not been met, you will be prompted when attempting
to leave the edit mode. You can let the system correct the programming automatically, or you can go back and change it manually,
using the displayed error message as a guide.
Time-Aligned Display Requirements. In addition to the
programming requirements listed earlier, there are certain conditions
that must be met before data can be correlated for display:
1. The state and timing memories must both contain the sample
event that caused the CL=O assertion.
2. The data in the state and timing memories must overlap at
some point in time (i.e., their time domains must intersect).
Position the state and timing triggers carefully to ensure that
the above two conditions are met. Only the state and timing data that
overlaps is correlated for display.
Crosslink Triggering (Non-Aligned)

In the non-aligned mode, the state and timing analyzers can
arm each other, but their respective data is not time-aligned for the
display. This allows greater flexibility in the available cross-arming and
triggering setups. You can use any of the triggering modes, including
Multiple-Preview Acquisition in the state analyzer, and Multi.:rriggers in
the timing analyzer. In addition, you can use any of the timing
analyzer's timebase selections.
Note that, as with any trigger mode, it is possible to program
arming/triggering sequences in which the state or timing triggers may
never occur. Think carefully about your trigger and crosslink programming in both analyzers.
In the non-aligned mode, the state and timing analyzers can
both sense and/or assert the Crosslink (CL) line. In the state analyzer,
the CL is sensed within each defined symbol in the Symbol Menu,
and the CL is asserted within each defined state in the Trigger-Store
Menu.

. . . . . . . . . . . . . . . 6 State & Timina Together
MODEL 2100

In the timing analyzer, two extra CL programming fields
appear in the Format Menu. As shown in Figure 6-3, one field
appears above the trigger pattern and the other appears below the
trigger pattern.
The field which appears above the pattern is used for
sensing the Cl signal asserted by the state analyzer. Using this field,
you can specify that the timing analyzer look for its trigger once the
state analyzer has asserted Cl, or you can specify that timing
analyzer looks for its trigger while the state analyzer is asserting Cl
(thus, creating a trigger window).
The field which appears below the pattern is used for
asserting CL from the timing analyzer.

As a simple example of the flexibility of the non-aligned

(2), once armed, it could trigger on its own programmed trigger pattern; and then (3), upon triggering, it could assert the Cl to arm or
trigger the state analyzer.

USING STATE & TIMING TOGETHER

You enter the aligned/non-aligned menus differently than you
enter the individual state and timing menu systems. The following
paragraphs describe how you enter the modes, then the menus.

Entering the Aligned/Non-Aligned Modes
The aligned/non-aligned modes can be entered at any time.
To do so, first enter the Configuration Menu (press M for Menus and
C for Configuration) and select the State & Timing Analyzers option.
The Configuration Menu will then list the aligned/non-aligned mode
choices.
Select your mode choice by pressing the return key. If your
choice is one of the aligned modes and if the current state sequence
or programming does not meet the aligned mode requirements discussed earlier, you will be prompted with the following message:
"Make all corrections to parameter violations (YIN)?"

If you press Y for Yes, the pAnalyst will make all the necessary
programming corrections. If you press N for No, you will need to
select another choice.
Once you have made a mode choice, press the return key
again. The pAnalyst will enter the state and timing menus.

Operating the State & Timing Menus
When using the state and timing analyzers together, or when
observing their correlated acquisitions, you may need to jump back
and forth between the state and timing analyzer menu systems and
command lines.
To do this, press M for Menus from the command line. The
current set of analyzer menus available (state or timing) is indicated
on the command line, in brackets, in bold video. Press function key
F1 to select STATE menus or press function key F2 to select TIMING
menus. The menu list will then change accordingly.
If at some point you need to identify which set of menus you
are using, simply press M for Menus. You'll see which menus are currently active. Once familiar with both analyzers, you will notice that
the state and timing menus are quite different and easy to
distinguish.

Saving Files in the 1/0 Menu
If you are operating the state and timing analyzers in the
non-aligned mode, the I/O Menu provides an additional field, labeled
I Instrument. As shown in Figure 6-4, this field lets you specify which
instrument is used during the I/O operation. You can select STATE,
TIMING, or STATE & TIMING.
If you are operating the state and timing analyzers in an
aligned mode, the Instrument field is not programmable. It is
automatically set to STATE & TIMING, so that the I/O operation is
performed on both analyzers.

SPLIT-SCREEN DISPLAY

A split-screen display mode is available if either of the
aligned modes has been selected. As shown in Figure 6-5, this mode
allows the simultaneous display of both timing and state data.
[B'" NOTE

It is assumed that the acquired state and timing data falls within the
same time domain, or that at the least the domains intersect.

In the split-screen display, both sets of data are shown in
their normal display mode. That is, timing data is shown in a waveform display, and state data is shown in a columnar radix display.
The split-screen shows up to 20 data lines, divided into two
windows. You can specify the relative size of the windows in the timing analyzer's Environment Submenu. As shown in Figure 6-6, the
submenu provides a field labeled State Split-Screen Size. This field
determines how many lines of the display are dedicated to the state
analyzer. You can enter any value into the field between 1 and 10,
inclusive.

timing analyzer's Environment Submenu.

All the display controls that are normally available for state
and timing displays, are available for the split-screen display. The
scrolling of the two display windows works in a master-slave fashion.
For example, if you use the up and down cursor keys to scroll the
state data, the timing waveforms are automatically scrolled left-to-right
to the next corresponding state clock region.
If you use the left or right cursor keys to scroll the timing
waveforms, the waveform display becomes the master. Calculations
are made by the software to determine if the waveform scrolling has
moved into a new state clock region.lf so, the state display is scrolled
accordingly. Should the scrolling action of one display force the other
past its data, a message will advise you that the system has been
scrolled beyond time-aligned data.
The split-screen mode becomes the default display mode
when an aligned mode is selected. To change to another display
mode, go to the waveform portion of the display, enter the edit mode,
and select another choice in the Memory Selection field.

Connecting the Probes. Now, connect the clock and data
probes as follows:
1. Attach the P2901 Clock Probe to the state analyzer controller
board.
2. Attach the P2902 Data Probe to the state memory board that
is farthest from the controller board. If this farthest board is a
32-channel memory board, attach the probe to the board's
upper probe connector.

THE CONFIGURATION MENU

If you've followed the instructions in the preceding subsection, you should now be looking at the Configuration Menu. Your
screen should be similar to the one shown in Figure 7-2, although
there may be some differences in the number and depth of memory
cards, and perhaps the location of the controller and memory cards.
If your screen looks like the one shown in Figure 7-3, one of
three things is probably wrong:
1. The power to the pAnalyst is not on.
2. The cable between the computer and the pAnalyst is not
connected.
3. The PC interface board (the small board that plugs into the
personal computer I/O bus) is set to a different address

Help also explains the command and message lines at the
bottom of the screen. These lines are very important in using the system. The command line provides supplemental information about the
command you have selected or, if you've made a mistake, gives you
an error message. Any time you are unsure of what to do next, read
the command and message lines. In most cases this will provide you
with the information you need to proceed.
To read the Help information, move the screen pointer to the

Now that you have read the Help information, we can proceed with the demonstration. In this demonstration we will be
monitoring and controlling the demo board that you have connected
to the clock and data probes.
The demo board consists of a 16-bit up/down counter. The
state analyzer can be programmed to control the up/down function of
the counter, its load initial count function, and its counter enable
input. Of course, the state analyzer also monitors the counter's 16

As we proceed through the demonstration, we will discuss
the operation of the demo board in more detail, and we'll clarify
exactly how to program the state analyzer to control and/or monitor
the board.
First let's go to the I/O Menu and load a setup file, which will
automatically program the entire operation of the state analyzer. Move
the screen pointer to the State Analyzer option in the Configuration
Menu, and press the return key.
The state analyzer will display its Format Menu first. To move
from the Format Menu to the I/O Menu, use the Menu command on
the command line at the bottom of the screen. Press M. The command line now lists all of the available menus, including the I/O
Menu. Press I to select the I/O Menu.

1. Press E to enter the edit mode.
2. Move .the screen cursor to the Path field and enter:

Now press the return key. The directory window should
immediately show you the files on the HELP DISK.
3. Move the screen cursor to the File Name field, then enter the
name of the DEMOXX file that matches the total number of
channels in your state analyzer. For example, if your state
analyzer has a total of 32 channels, enter DEM032.
4. Move the screen cursor to the Function field, then, using the
space bar, set the field to:
LOAD SETUP

5. Finally, press the escape key to leave the edit mode and
return to the command mode.
Your I/O Menu should now look similar to the one shown in
Figure 7-6.

LB" NOTE
In this example, we used the DEM032 file because our state
analyzer is configured with a total of 32 channels. If your state
analyzer contains more channels, you should be using the appropriate file. Otherwise, the demonstration example will not work properly.

THE FORMAT MENU

The Format menu is used to describe how you have connected the state analyzer to the device under test, and how this set
of connections should be grouped, named and displayed. It also
allows you to name the setup Gust as we named the demo setup
DEMOXX).
The demo board counter outputs are connected to the channels marked A in Figure 7-9 and on your screen. For the configuration shown in Figure 7-9, you can see that the data probe connected
to the demo board is received by the upper probe connector of the
32-Channel Memory Board in slot number 3.
This group of lines has been named Counter on the righthand side of the screen under the NAME column. They are to be
displayed in positive logic (POL=+) and in hexadecimal notation
(RADIX=HEX). In the Display Menu, the data acquired from these
lines will be in a column that is titled Counter.
We're going to defer further explanation of the Format Menu
until we've run the state analyzer a few times and have learned a little
more about how the demo is constructed.

cause the data presented to the state analyzer to be different each
time we run the machine, by making changes in the Format Menu.

BUS DEMULTIPLEXING

The way you program the Format Menu affects the way data
is acquired and displayed. This subsection discusses how the sample
and hold clocks work together to capture different kinds of data.
As explained in the material on sample and hold clocking in
Section 4, the state analyzer in MUX mode (where MUX=YES) looks
at only the lower a lines of the data probe. These lines are run
through two transparent (or presample) latches in parallel, so that the
a lines are duplicated and two sets of a are presented to the rest of
the memory board (shown on paths A and B in Figure 7-17.) Each of
these sets of a can be presampled with its own hold clock and held
until the data is clocked into the state analyzer with the S1-S5 sample
clocks.
If both H1 and H2 are high and MUX=YES, then both a-bit
paths will present the same data to the internal logic of the state
analyzer's memory board. However, if one or both of the hold clocks
are active, and if the phase relationship between the hold clocks is
not the same, then different sets of data can be clocked into the internal logic of the memory board.

7 Demonstration • • • • • • • • • • •_
MODEL 2100

Look at Figure 7-18 and you will see three examples of sample and hold clocks vs data storage for multiplexed systems. The first
two examples (shown in Figures 7-18A and 7-188) are timing diagrams
of the demo board. In these diagrams, the sample clock data is the
data on path 8 of Figure 7-17. Likewise, the hold clock data is the
data on path A.
In the Format Menu shown in Figure 7-16, path 8 data is the
group associated with H2. Path 8 is always transparent, because
hold clock H2 has been programmed don't care (i.e., pass always).
Path A, the data above path 8, is transparent when its hold
clock field is programmed to don't care. If path A is programmed to
H1 and the current definition of H1 is LO=PASS (HI=HOLD), then the
shaded area in Figure 7-188 represents the period when the presample latch is transparent and the white area represents the period
when it is holding latched data.
Figure 7-19 shows the schematic for the demo board. As you
can see, the counters are clocked on the rising edge of H1, and H1
is delayed relative to S1 by two gate delays. Also, remember that the
counters are clocked into the state analyzer on the falling edge of S1.
Starting at the left side of the timing diagram in Figure 7-188,
you can see that shortly after the first rising edge of H1, the sample
clock data (the lower 8 bits of the counter) changes to the value 57.
The next falling edge of S1 (marked with the vertical line) clocks the
sample and hold clock data into the state analyzer so that the displayed value is 5756. (This is the first value displayed in the column
just past the far right-hand side of the timing diagram.) The 57 is the
sample clock data and the 56 is the hold clock data. Why the hold
clock data is 56 will become apparent as we go through the next
cycle of the timing diagram.
Immediately after the first falling edge of S1, H1 goes low,
causing the hold clock data presample latch to become transparent.
Shortly after this latch has been enabled, the data in the latch
becomes 57 as indicated. The 57 is the current value of the lower 8
bits of the counter.
Upon the next rising edge of H1, two things happen: the
hold clock data is latched into the presample latch, and the counters
are clocked. After a propagation delay from clock to counter is output, the counters increment to the value 58.

7·24

• • • • • • • • • • • • 7 Demonstration
MODEL 2100

At this point the counters (and therefore the sample data
path) have the value 58, while the hold clock presample latch has the
value 57. The presample latch will hold the value 57 until H1 goes
low. However, before this happens S1 goes low, clocking the value
5857 into the state analyzer. (The next four cycles of the timing diagram are left as an exercise for the reader.)
In Figure 7-18A, you can see that if the programmed polarity
at H1 is reversed (in relation to Figure 7-188), sample clock data and
hold clock data will be the same at the time S1 clocks the data into
the state analyzer. This is because both the sample and hold clock
presample latches are transparent (enabled) before and during the
S1 falling edge.
Now that you understand how programming the Format
Menu in different ways can result in the state analyzer seeing different
data, let's go on to the Trigger-Store Menu and learn how trigger
specification separates one kind of data from another.

Figure 7-21. The Trigger-Store Menu with all the states programmed.

Data values in the trigger-store specification are represented
symbolically. Figure 7-22, a listing of the Symbol Menu, gives you a
quick reference for the hexadecimal value of any word recognizer.
Perhaps the best way to look at the trigger-store specification
is as a small high-level language program consisting of up to 15
procedures. Each procedure corresponds to the labels in the STATE
column down the left-hand side of the specification (see Figure 7-21).
Each procedure (or STATE) consists of a number of lower
level statements that allow you to jump to (GOTO) other procedures;
to halt (TRIGGER); and to execute 110 as a function of the data monitored by the state analyzer's data probes (where Input = STORE and
Output = Real-time Programmable Outputs).
At this point the analogy breaks down, because, in the
analyzer's state machine, all the lower level instructions within each
procedure can be executed in parallel (simultaneously), rather than
serially as in a computer program.

• Figure 7-22. The Symbol Menu.

One last piece of information before we go through the
trigger-store program. On the right-hand side of the screen there is a
column labeled RPO. The values in this column determine the levels
the two Real-time Programmable Outputs (RPOs) on the clock probe
take upon leaving the state they are specified in. These RPOs are
connected to the demo board in such a way that they control the
up/down function and the load line of the counter: Table 7-1 lists the
state the counter will take on for a given RPO programming.

When you execute the Go command, the initial RPO value
will be O. When the counter is forced to load, the value it loads will
be 5555 if the jumper is removed from the demo board, or 1555 if
the jumper is installed.
We'll begin with state START in Figure 7-21. (Follow along on
Figure 7-21 and your flowchart.) In this state, the first data value
clocked into the state analyzer (anything=XXXX) will cause a jump to
state TSTMX. It will also set the RPO value to 3, causing the counter
to begin counting up from either 1555 or 5555 (depending on
whether or not the jumper is installed).
In state TSTMX, the idea is to differentiate between data
acquired in MUX mode and data acquired with MUX turned off. We
know that in state START the counter was loaded with 1555 or 5555,
and will now begin counting up. If (as explained previously) the Format Menu is in MUX mode, the upper and lower 8 bits of data will
begin counting up simultaneously from either 5555 or 5655. One
clock later their value will be 5656 or 5756.
These values correspond to the symbol Multiplex, and will
cause the state machine to jump to the state MUX and continue to
count up (RPO=3). If, however, the Format Menu has been used to
turn MUX mode off, then the state analyzer will see a 16-bit counter
begin to count up from either 1555 or 5555, eventually reaching the
value of 5557 (Non-mux) before it counts through the Multiplex
values. Non-mux will cause a jump to state NOM UX and will put the
counter in a load condition (RPO=O).
We will follow the Multiplex path first and return later to the
Non-Mux path.
State MUX will differentiate between data where the upper 8
bits equal the lower 8 bits, and data where the upper 8 bits have a
value one greater than the lower 8. The state is looking for the Shift
symbol (value 5A59) before 1000 counts have gone by.

7-32

• • • • • • • • • • • • 7 Demonstration
MODEL 2100

We know that upon entering the state MUX, the count was
either 5656 or 5756. Three clocks later it will be either 5A59 or 5959.
If, on the Format Menu, the H1 hold clock is selected, the count
value will be 5A59. The upper data bits and the lower data bits are
not equal, and the state machine will jump to the state NOT=. If the
hold clock is off (hold clock=X), then the value 5A59 will never occur,
because the upper 8 bits will always equal the lower 8 bits. After
1000 clocks, the state analyzer will trigger from state MUX as
directed.
State NOT= is being used as a marker. The state analyzer
triggers as soon as it enters this state. Without looking at the
acquired data, we know something about the sequence of data just
by seeing the triggering end point. Marker states like this one are
very useful in manufacturing test situations where the end points of
tests can be states with labels such as Pass or Fail, depending on
the sequence of data acquired.
Returning now to the Non-Mux path, state NOMUX determines whether or not the jumper is installed on the demo board. If
the Low Reset symbol (value 1555) is detected, the jumper is installed
and the state machine jumps to state WAIT, leaving the counter in
load mode (RPO=O). If, however, the jumper is not installed, the HiReset symbol (value 5555) will cause the state machine to jump to
state CNTUP. Effectively, the state machine remains in state WAIT until
the jumper is removed from the demo board.
In state CNTUP, the counter counts up until it rolls over twice
and again reaches the count 5555 (Hi-Reset). Then the state machine
jumps to state DNCNT and instructs the counter to count down
(RPO=2).
In state DNCNT, the counter counts down until it rolls over
once and again reaches the count 5555. At that time the state
machine causes the analyzer to trigger.
In each of the states in the trigger specification (shown in
Figure 7-21), the state analyzer was directed to NEVER STORE. Even
though the data was monitored and the state machine made decisions based upon this data Uumping, setting the RPOs, and triggering), no data was stored. No data, that is except the trigger word.
Regardless of the store specification, the trigger word is always
stored.

M PA allows us to view the seven cycles immediately preceding every qualified acquisition. A qualified acquisition is defined as:
any data stored as the result of the store specification within a state;
the trigger word; or state transitions, if the Store All State Transitions
field is set to YES.
Because the demonstration trigger specification now contains
NEVER STORE in all states, the only qualified acquisitions will be the
trigger word and state transitions. If we enable MPA mode, we will be
able to see the seven unqualified cycles leading up to the trigger and

Before executing the Go command, return the Format Menu
to non-mux mode with the hold clock programmed to X. Execute the
Go command and re-enter the Display Menu. Your screen should
look like the one shown in Figure 7-29.

Figure 7-29. The MPA Mode.

If you display does not look like Figure 7-29, but the trigger
word is in state DNCNT, then enter the edit mode and move the cursor to the programmable field under the LOC column. Press B. Your
screen should now look like Figure 7-29.
Note that all qualified acquisitions are marked with a right
arrow (see callout 1 in Figure 7-29). The spaces between blocks of
data indicate that an indeterminate number of cycles, which were not
recorded, occurred between one block and another. (A cycle is the
synchronous data presented to the state analyzer by the logical OR
of the non-overlapping clocks, S1-85, depending on which sample
clocks you have connected.)

7-40

• • • • • • • • • • •_ 7 Demonstration
MODEL 2100

In general, a block of data will consist of one qualified acquisition and its seven preceding cycles (e.g., the block associated with
the right arrow). However, if a qualified acquisition occurs before
seven unqualified cycles do, the qualified cycle will be marked
wherever it occurs within the blocks, and the block will be padded
out with cycles occurring immediately after the qualified cycle. This
will continue until the block is filled (with a total of eight acquisitions).
If more than one qualified acquisition occurs within a block,
all of them will be marked (see callout 2 in Figure 7-29).
In MPA, spaces between lines of data (see callout 3 in Figure
7-29) indicate that some number of unrecorded cycles occurred, and
lines of data without spaces represent contiguous cycles.
Now let's see how to use the trigger-position delay counter
both in and out of MPA mode.
Enter the Trigger-Store Environment Submenu and turn off
MPA mode. Then, enter the Trigger-Store Menu and press E for Edit
mode. Move the screen cursor to the Trigger Position (TRIG paS)
field at the top of the screen. (If MPA mode were on, the field would
not appear in reverse video, and you would not be able to change
it.) Once in this field, scroll through your choices. You should see DLY
0000, BEGIN, CENTER, and END as your options.
The trigger-position delay counter-the DLY field-is used to
specify how many acquisitions are to occur after the trigger. Thus,
DLY 0005 will cause five acquisitions to be stored after the trigger
line of the display. For convenience, BEGIN, CENTER, and END are
preprogrammed values. For a memory depth of 4096, these have
values of 4082, 2047, and 13 respectively.
Program the trigger position to DLY 0002. Then, use the
down cursor key to move state DNCNT onto the screen.

THE STATE DISPLAY

By this time you have used the Display Menu repeatedly, but
we have not talked about many of the commands, nor about the Display Environment Submenu. If you have not already done so, read
the Display Menu subsection in Section 5.
Now let's try using the Find command. Enter the Display
Environment Submenu by pressing V for enVironment, then D for Display. Move the screen cursor to the Find Pattern field and scroll the
Hi-Reset symbol into view. Now press the insert key. This will cause a
Followed By field to appear. Again scroll the symbols through this
field until the Hi-Reset symbol appears. Your screen should now look
like Figure 7-32.
The find specification will look for a 5555, followed by a 5555
within 01 location every time the Find command is executed in the
State Display.

shown in Figure 7-31), note that the first occurrence of the data
sequence:

5555
5555
ends on line -0003. Execute the Find command. Note that line -0003
is now at the top of the screen. The next occurrence of the specified
sequence ends on line +0001. Execute the Find command again.
Now reverse the pattern search direction by pressing the < (less
than) key. Try the Find command several times in this direction.
Now let's try using the compare acquisition to reference
memory feature. First clean up the display by entering the LOC field
and pressing B. Your display should look like the one in Figure 7-31.
Select the < -ACO REF- > option at the top of the display.
Escape from edit mode and execute the Ref < -acq
command. Your screen should look like Figure 7-33.

To acquire. data that differs slightly from the current reference
data, run the state analyzer again, but this time with the jumper
installed on the demo board. (Remember to remove the jumper when
the "RUNNING in State WAIT" message appears.) After you execute
the Go command, your display should look like the one in Figure
7-34.

Figure 7-34. Data acquired for comparison.

Notice two things about this display. First, the acquisition and
reference displays are aligned in relation to their trigger words, unless
you've specified an offset in the Display Environment Submenu. (The
offset is currently 0.) Second, state labels are never compared. (Note
line -0004 where the data is the same but the labels differ.)
Execute the NexLdiff command. Note that the first difference
(which is highlighted) moves to the top line. Try NexLdiff a few more
times. Also change direction and try it.
We will now go through an exercise that will teach you a few
new things and allow you to practice much of what you have already
learned. The objective is to step the counter a few counts at a time.
This will illustrate how the state analyzer can be used to single- or
mUltiple-step a microprocessor in your prototype.

The number of data bytes is
determined by the following formula:
saved_pod_count * 2
where saved_pod_count equals
the number of pods that were available when reference data was saved.

The time bytes are reserved for time
data acquired via the Time Stamp.

As shown above, each word of the stored reference data is
comprised of the flag byte and the (saved_pad_count * 2) data
bytes. Each word may also contain four time bytes, depending on
whether or not the Time Stamp (Option 003) was used to acquire
time data. The reLhas_time flag indicates whether or not the time
bytes are present.

CLOCKING EXAMPLES

This appendix provides several examples of how to use the
state analyzer's clocking to acquire data from a microprocessor under
test. Each example shows how to connect the data and clock channels to the microprocessor pins, and how to set up the Format Menu.
The microprocessors used for the examples include:

Z80
8085
8086
8088
68000
If you are attempting to acquire data from a microprocessor
that is not discussed here, use the following examples as a guide.
All of the above microprocessors are also supported by the state
analyzer's Mnemonic Disassembler kits. These kits provide a singleplug probe connector, as well as preprogrammed disassembler software. For details, see Related Products and Options at the front of
this manual.
