Nice! I've been following waferspace and tiny tapeout loosely but I'm sadly not in a position to be able to work on something right now.

I'm surprised you managed to fit something like this in a TT grid square.

You can join multiple Tiny Tapeout tiles (grid squares) together to form bigger projects, which is what I did here. It's actually one of the bigger 4 grid projects.

Also how much you can fit really depends on the node the shuttle is targeting. So I was in luck that this was on Global Foundries 180nm as you can cram in a lot for flip-flops onto a single tile compared with Skywater 130nm. On the other hand the gates are much slower than on Skywater 130nm.

Hopefully both programs will be around for a while, so if you are still interested when you have more time you can join the shuttle then.

You can check out the tiles for this project and their exact location on the TT chip[0].

Nice, thanks for posting the link. For the people unfamiliar with the Tiny Tapeout program: everyone that gets a copy of the Tiny Tapeout chip will be getting a copy of all the ASICs on the shuttle.
