alt Hacker NewsNice! 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.
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.

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.
