Collection of verilog modules and projects
Some of them are purely simulations and others require real hardware. Some have diagrams done in https://github.com/hneemann/Digital.
Note: the "board" selected in each project is irrelevant because I'm only running a simulation and not attempting to upload to board. This simply allows apio to build.
> apio init --board TinyFPGA-B2
> apio build
Or for simulation only:
> apio init --board TinyFPGA-B2
> apio sim
Simplified 8bit CPU similar to Ben Eater's SMP. https://www.youtube.com/c/BenEater/videos Schematics: https://eater.net/8bit/schematics
VGA TFT
I simple MC6809 adapted from Ben's CPU.
A non-cycle accurate implementation.
