Setting Up NativeLink and Simulation Settings

To set up the NativeLink and simulation settings, follow these steps:

  1. In the Quartus® Prime software, on the Tools menu, select Options.
  2. In the Options dialog box, under Category list, expand General and then select EDA Tool Options.
  3. In the EDA Tools Options window, follow the settings as shown in the following figure:
    Figure 14. EDA Tools Options Dialog Box

  4. In the Quartus® Prime software, on the Assignments menu, click Settings > Simulation.
  5. Create a new testbench and name it tb and include all necessary files.
  6. Enter the necessary NativeLink settings. The following figure shows an example settings.

  7. Run Analysis and Synthesis.
  8. To view the simulation results, on the Tools menu, select Run Simulation Tool and then click RTL Simulation.
    For a successful simulation, you may need to manually change alterapll.vo to alterapll.v in the auto-generated file.
  9. Before running the Fitter, ensure that the following settings are done in the Assignment Editor.
    • I/O Standard
    • Input Termination
    • Output Termination
    • DQ Group
    • Location assignment for strobe pin—this helps the Fitter to fit the related DQ pins in the appropriate l/O sub-banks. You can then back-annotate the locations if desired.
    The following figures show a setting example in the Assignment Editor and the Pin Planner result:

  10. Run the Fitter, Timing Analysis, and Assembler. Refer to SDC Walkthrough for more elaboration on the SDC constraint examples included in this design example.
