Overview

Baseline Design

Starts from IOP example

  • Similar to Arduino "Blink Sketch" and uses the following resources
    • Timer Unit 0 1 second timer
    • On-board LED
  • The Timer unit could be removed if desired
    • Timer makes Blink easier

Steps

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

Clone Sources

Alternately download ZIP files

  • Alternately you can download the two ZIP files from GitHub

  • Unzipped into the same folder

  • Rename the folders to remove the -main from the folder path

Build Minimal Example

Start by building the minimal example in Quartus II

  • 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
  • Open the Project file in Quartus II

  • Entities in Quartus should look like

  • Build FPGA (click the blue "Start Compilation arrow)
  • Build does not verify the ROM file
    • May need to re-point to the ROM .MIF file since Quartus II sometimes "forgets"
    • Double clicking on the IOP_ROM file

  • Hit finish, if you get error

  • Re-point to the ROM file
  • Make sure to select .MIF file extension
