It's fun!

I had heard of the TinyTapeout project before, but I think it only worked for purely digital input and outputs? The idea of having a custom chip design made would surely attract a lot more people if it could include analog functionalities.

It uses Yosys? with some custom modules/libraries?

Pure digital ASICs would certainly attract many people.

The problem is more with the specs they offer. They do not support gate-level synthesis, but tile-based, a bit like FPGAs, with pretty severe limitations: https://tinytapeout.com/faq/#chip-specs-for-tt01-tt02--tt03
12.5kHz (!) max freq for their past shuttles, and for the coming one, they say about 50MHz. Much better, but still pretty low for the kind of stuff you'd typically want an ASIC.

That's cheap though. Also, I haven't seen the exact terms regarding IP, but since they are using the Skywater PDK, I guess the same licensing applies, so your designs must be fully open-source? To be confirmed though.

Nice option
