How it works

This is a tiny FPGA. It has 4-input LUTs and a routing fabric!

This project was a spontaneous submission. I did not have the time to properly validate, document or optimize the design.

How to test

If you are still undeterred:

  1. Generate a bitstream using the bitstream tools
  2. enable the configmode pin (ui_in[7])
  3. shift the bitstream in
  4. test the fpga using the io pins

It might be advisable to read the testbenches in https://github. com/recursivetree/fpga/ to see how it works.
