Been studying RISC-V for… I think a year now. Bought the booklet outlining the ISA’s modules, and have been working down from there.
I have seen various startups and actual products, as well as a bunch of simulators, but I haven’t really seen any projects trying to design a RISC-V CPU from the ground up.
Are there any groups doing this? I don’t think I’m at a point where I could meaningfully contribute, I’m mostly interested for educating myself.
I guess just making sure my understanding aligns - RISC V being the instruction set, and you are wondering if anyone is building a CPU to implement it?
Came across a couple examples, if that’s what you mean

Cloud

That’s correct. I’m interested in seeing hardware implementations of it.
I know LTT has a bit of a bad wrap these days. But he had a video on RISC V a while ago, in a desktop computer https://youtu.be/vaMxTSm53UU?feature=shared
I’d recommend the Explaining Computers videos on RV over LTT, especially since the guy at EC does a lot more research into RISC-V, and does yearly “state of RISC-V” videos.
Thanks for the recommendation!
xiangshan , rocket chip , cva6 , ibex .
All of these are built by non profits (although some of them are more like “trade groups” and not “charities”).
xiangshan is probably the most interesting, there is also vroom but it seems inactive for now.
