• cd /src
• run make
• all tests should pass
• run gtkwave ./tb.vcd to view the waveforms

• test and develop this locally without using GH Actions following https://discord.com/channels/1009193568256135208/1009193568256135211/1038381997493592104
• implement this using direct logic instead of a generated LUT (did the synthesizer already infer what I was doing with the passthrough?)
• Use don't care for the default case in the case statement, which would probably propogate errors better for simulation

TinyTapeout is an educational project that aims to make it easier and cheaper than ever to get your digital designs manufactured on a real chip!

Go to https://tinytapeout.com for instructions!

Edit the info.yaml and change the wokwi_id to match your project.

Please see the instructions for:

• Enabling GitHub Actions
• Enabling GitHub Pages

When you edit the info.yaml to choose a different ID, the GitHub Action will fetch the digital netlist of your design from Wokwi.

After that, the action uses the open source ASIC tool called OpenLane to build the files needed to fabricate an ASIC.
