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. 9 / 28 STEP-MXO2 Software Manual 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. 10 / 28 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: 11 / 28 STEP-MXO2 Software Manual 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: 12 / 28 STEP-MXO2 Software Manual 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 13 / 28 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. 14 / 28 STEP-MXO2 Software Manual 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. (3)Write Verilog code in this file, press Ctrl+S to save your files. The IDE will save the file to the File List. Enter the code shown below. 15 / 28 STEP-MXO2 Software Manual module and2 ( a, b, c ); input a,b; output c; and(c,a,b); endmodule (4)Select ‘Process’(on the left side of screen), double click ‘Synthesis Design’, Synthesis your design. (5)If synthesis successfully, it will display a green tick on the left side of ‘Synthesis’; if synthesis fault, it will display a red cross. Check out the error and modify your code until successful synthesis. 16 / 28 STEP-MXO2 Software Manual 3.3 Assign Pins (1)Select Tools→Spreadsheet View. Or Tools->Spreadsheet View 17 / 28 STEP-MXO2 Software Manual (2)Assign the a to Pin(L14), B to Pin(M13), C to Pin(N13), press Ctrl+S to save it. 3.4 Generate the compiling files and download (1)The design is simple, we don’t tell you some of the things about Simulation, Layout, route. And we create the compiling the files directly. (2)Select the ‘JEDEC File’ and double-click the ‘Export File’. 18 / 28 STEP-MXO2 Software Manual (3)Open the Programmer, Click Tools→Programmer(Don’t forget connect the STEP-MXO2 to PC). (4)Before programming, the IDE will create as new project from a JTAG scan, you can click ‘Detect Cable’ to detect it, if your device driver install successfully, then click ‘OK’. 19 / 28 STEP-MXO2 Software Manual (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 20 / 28 STEP-MXO2 Software Manual 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; 21 / 28 STEP-MXO2 Software Manual b=0; #50 a=1; b=0; #50 a=1; b=1; #50; a=0; b=1; end and2 and2_u1( .a .b .c ); endmodule (a), (b), (c) 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 22 / 28 STEP-MXO2 Software Manual Pop up a properties window, change the file attribute value to simulation. 23 / 28 STEP-MXO2 Software Manual 4、Choose the menu Tool -> Simulation Wizard or click the button in the toolbar, start the simulation wizard. 5、Pop up a simulation wizard window. 24 / 28 STEP-MXO2 Software Manual 6、Set a name for the simulation project. 7、Choose the Process stage, now in the functional simulation you can only select RTL. 25 / 28 STEP-MXO2 Software Manual 8、Select add or remove to the Simulation of the Source files and test, if select the Copy Source to Simulation the Directory option, will copy the source file to the directory of simulation project. 9、You can select the simulation top module. 26 / 28 STEP-MXO2 Software Manual 10、Now the simulation project has been created. 11、Finish the simulation wizard ,you can see the Wave after the simulation. 27 / 28 STEP-MXO2 Software Manual 5．Version Version number Date Comments 1.0 2017.2.14 Initial Version 28 / 28
