Build Minimal Example

Start by building the minimal example in Quartus II

  • Entities in Quartus should look like

  • This example does not cover porting to a different FPGA card
    • Will need to adjust I/O pin assignments if a different FPGA is used
  • May need to re-point to the ROM .MIF file since Quartus II sometimes "forgets"
    • Double clicking on the IOP_ROM file

Steps

  • Copy baseline design
  • Select/add peripherals
  • Create new peripherals
  • Write assembly code

Baseline Design

  • Starts from IOP example
    • Similar to Arduino "Blink Sketch" and uses the resources
      • Timer Unit 0 1 second timer
      • On-board LED
    • The Timer unit could be removed if desired
      • Timer makes Blink easier
  • Copy the minimal design to a new folder
