My own Verilog components library. Anything from a flip flop to an ALU.
New designs will be tested with cocotb, as can be observed in basic/muxes/ which is the first design adopting this scheme.
For tests using cocotb, simply:
make to compile and run tests
make wave to view waveforms in GTKWave
make cleanup to clean-up build and accessory files
You will get something like the following image:
Where still outdated, vestiges of the old testing procedures are still present (traditional Verilog testbench plus run.sh bash script to compile with Icarus Verilog and open waveform in GTKWave). For those, simply execute run.sh in your terminal.
