I&#x27;m still not sure whether RISC-V will be one of main stream microprocessor in the industry field.<p>1. Still the core is not yet solid.<p>2. Not much powerful debugging tools exist.<p>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.<p>4. BSD itself. It is strong and also weakness. There&#x27;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.<p>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 &quot;I was wrong at that moment&quot; after all.
