It&#x27;s a neat idea but I doubt it will happen. He has to build and test all the components, from MCU to I&#x2F;O, plus fab it all for $20,000. By himself. I might believe it for a FPGA project but not an ASIC.<p>So, it&#x27;s a good project. I&#x27;ve promoted doing a RISC-V dropin for Arduino&#x27;s. I see the vision. He might just be better off tweaking some stuff on OpenCores, esp changing decoder for RISC-V, then integrating it. Get money some other way to cover testing the pieces in shuttle runs. Once they all work, then test the whole thing with a big run that produces a big batch of chips.
