I'm still not sure whether RISC-V will be one of main stream microprocessor in the industry field.
1. Still the core is not yet solid.
2. Not much powerful debugging tools exist.
3. Chisel itself. Every engineer who is willing to use RISC-V should understand output of chisel source code in order to do ECO or some other low level jobs.
4. BSD itself. It is strong and also weakness. There's no way to merge revision into main repository. It will not be quite trouble if RISC-V remains as it is. But will be a big problem if RISC-V evolves by its own development team.
I hoped this RISC-V becomes mainstream processor since I attended the lecture from Mr.Yunsup Lee 4 years ago. I really want to say "I was wrong at that moment" after all.

- zhemao 11y agoThere's a distinction between the RISC-V ISA and our open source processor implementations. The ISA is an open standard that anyone can make an implementation of. There are many RISC-V implementations out there. Most of them are not based on our RocketChip codebase and use Verilog, not Chisel.
