Trying to learn about opensource Silicon manufacturing. - eviltoast

I’ve wanted to contribute to open source projects for years. Ive contributed to a few things in the past, but my expertise just isn’t in programing (I’m a physicist), so it’s hard to contribute meaningfully. Recently, I’ve heard about some open source silicon manufacturing and I’m intrigued, this is something I think I could contribute to significantly. I know of LibreSilicon, but I want to learn about other projects as well, and are there good resources to learn about the current state of projects. Thought I’d see what y’all know.
