Creating a New Simulation Project Using Simulation Wizard
This section describes how to use the Simulation Wizard to create a simulation project (.spf) file so you can import
it into a standalone simulator.
The Simulation Wizard Project (.spf) file and a simulation script DO file are generated after running the wizard. You
can import the DO file into your current project if desired. If you are using Active-HDL, the wizard will generate an
.ado file and if you are using ModelSim, it creates and .mdo file.
Note: PCS configuration file, (.txt) must be added in step 6.
Setting Global Preferences in Diamond
To set any of the Global preferences in Table 15-11, do the following in Diamond:
• Invoke the Spreadsheet View by selecting Tools > Spreadsheet View.
• Select the Global Preferences Tab beneath the Spreadsheet View pane as shown in Figure 15-14.
• Right-click on the Preference Value to be set. In the drop-down menu, select the desired value.
1. In Project Navigator, click Tools > Simulation Wizard. The Simulation Wizard opens.
2. In the Preparing the Simulator Interface page click Next.
3. In the Simulator Project Name page, enter the name of your project in the Project Name text box and

browse to the file path location where you want to put your simulation project using the Project Location
text box and Browse button.
When you designate a project name in this wizard page, a corresponding folder will be created in the file
path you choose. Click Yes in the popup dialog that asks you if you wish to create a new folder.
Valid types are RTL, Post-Synthesis Gate-Level, Post-Map Gate-Level, and Post-Route Gate-level+Timing.
Only those process stages that are available are activated.
Note that you can make a new selection for the current strategy if you have more than one defined in your
project.
The software supports multiple strategies per project implementation which allow you to experiment with
alternative optimization options across a common set of source files. Since each strategy may have been
processed to different stages, this dialog allows you to specify which stage you wish to load.

the local simulation project directory you just created, check the Copy Source to Simulation Directory
option.
