Re: So, do tell (Score 1)

Many componies have closed source riscV implementations that they sell. Because, although the ISA is open source, the guys that write verilog, do the verification, make the physical layout still eat regularly, pay mortgages and have kids studying. RiscV, the ISA, is open source which is awsome because people have a community maintained compiler but they'll still need to do the hardwork or buy closed source solutions. Any optimized cores will never be freely open because that involves a considerable investment. This is not software.
