3.1. Generating the Platform Designer System

After making any changes in the Platform Designer project for the Drive-On-Chip Design Example, generate the system.
  1. Open Quartus Prime Pro, navigate to Tools > Platform Designer.
  2. Open the .qsys file located in /rtl/top_qsys.qsys.
  3. In Platform Designer click File > Save.
  4. Click Generate HDL….
  5. Click Generate.
  6. Click Close.
  7. If your changes result in new exported connections you can view the Platform Designer component template by clicking Generate > Show Instantiation Template….
    Add new ports to the Platform Designer component instantiation in the top level RTL of the project <project variant>.v.
  8. Close Platform Designer.
After making a change to the Platform Designer system you must:
  • Regenerate the Nios V/g board support package (BSP) with new BSP settings file and rebuild the software.
  • Regenerate the .hex files for memory initialization.
  • Recompile the hardware
