16.In the InstallShield Wizard Complete dialog box, read the note and click Finish.
2.3 Licensing for Diamond
At the end of the installation, you will use the Lattice website-based licensing capability to
license your Diamond and stand-alone Power Estimator software.
To use the software, you must receive a Lattice Semiconductor softwarelicense based on the
identification of your network interface card (NIC). The NIC ID or equivalent is the
12-character hexadecimal physical address.
License your software early to avoid any down time.
To obtain a license file for your Diamond software:
1. Go to Lattice Semiconductor Software Licensing page:
www.latticesemi.com/licensing
2. Select Lattice Diamond.
You will get the Lattice Diamond Software Licensing page.
STEP-MXO2 Software Manual
10 / 28
Fill in your MAC address(12-digit hexadecimal value), Verify it, and click the “Generate
License”.
Then the license file (License.dat) will be send to your e-mail.
In the process of installing Diamond Software, the environment variables will be added to
your system, so you just need to copy the license file(License.dat) to the Folder named
“License”, For example:
Open Diamond and use it.
Notice:
If it reports error when you open the diamond, it means that the environment variable set up
error, check your environment.
STEP-MXO2 Software Manual

First, Right Click “This PC”, select“Properties”, click“Advanced system settings”.
Then, click “Environment Variables..”,
Check out “user variable for PC”, if there are some environment variables conflicts with
system environment variables “LM_LICENSE_FILE”, find and delete it(them); if there are no
environment variables called “LM_LICENSE_FILE”, just create it as same as the system
environment variables “LM_LICENSE_FILE”. For example:

3．Creating a New Project
3.1 Creating a New Project
The New Project wizard steps you through the process of creating a new project, allowing
you to name the project and its implementation, add source files, and select a target device.
You can open the New Project Wizard using one of the following methods:
On the Start Page, select New in the Project pane.
From the File menu, choose New > Project
Several example project design files are included in Lattice Diamond. The following example
procedure shows how to create a new project using the“and2” example.
On the Start Page, select Project > New.
Click Next to open the Project Name dialog box.
Click Browse to open the Browse for Folder dialog box. Navigate to the Lattice Diamond
examples directory and select the and2 folder, as shown:
STEP-MXO2 Software Manual
13 / 28
Enter a Project Name: and2.
Enter an Implementation Name: impl1.
Click Next to open the Add Source dialog box.
From this dialog box, you can add Verilog or VHDL source files, EDIF netlist files, LPF
constraint files, schematic, debug and analysis files or any other project files. Diamond takes
STEP-MXO2 Software Manual

the source files and places them into the correct folders for the new project.
Click Next to select the device(Family: MachXO2, Device: LCMXO2-4000HC, Performance
grade: 4, Package type: CSBGA132, Part Names: LCMXO2-4000HC-4MG132C).
Click Next to open the Select Synthesis Tool dialog box. Select the synthesis tool that you want
to use.If you are designing for MachXO, MachXO2, MachXO3L, or Platform Manager, you have
the option of using Lattice Synthesis Engine (LSE) as your synthesis tool instead of Synplify
Pro for Lattice or another third-party synthesis tool. LSE is a synthesis tool custom-built for
Lattice products and fully integrated with Diamond.
Click Next to open the Project Information summary.

At this step or any other step in the process, you can click the Back button to review or
change your selections. Click Finish. The newly created project, shown in, is now created and
open.
3.2 Add the design files
(1)Select File→New→File, create the new files.
(2)Select the file type, add Verilog Files, input the name of Verilog file, then click ‘Yes’, the
Verilog File will be created in your project.

(5)Click the program button, and when program complete, it will display ‘PASS’.
Let’s see the running results by STEP-FPGA MXO2. This example is a simple, two inputs logic
gates ‘AND’, the control of a development board with the bright lights out. When the single of
LED on the STEP-FPGA is low, the led will be brighten, and initial state of button is high, when

you push it, the single of button is low.
So, when the FPGA is running, the led will be brighten if you push any button.
4．Active-HDL quick start
Diamond provides you with an interface to create a new simulation project file that you can
import into a standalone simulator. Diamond supports Active-HDL and ModelSim simulation file
for file exports.Now let’s see how to quick start to use the integrated tool Active-HDL in the
Diamond for functional simulation.
1、 First of all you can create a testbench file as Verilog source files.
2、an2_tb.v ：
`timescale 1ns/100ps
module and2_tb;
reg a,b;
wire c;
initial
begin
a=0;

b=1;
#50;
a=0;
b=1;
end
and2 and2_u1(
.a (a),
.b (b),
.c (c)
);
endmodule
3、To note here is that the testbench files are only used for the simulation, a lot of statements are
not comprehensive. You must change set up the testbench file attributes to simulation
only.Right-click on and2_tb file in project directory
STEP-MXO2 Software Manual
