Right now, the "official" RISC-V reference implementation, Rocket, is still ASIC-optimized. FPGA-based RISC-V cores tend to be home-grown things these days.
You can still synthesize Rocket on an FPGA, but because it's optimized for ASICs, it needs a rather large FPGA to do so, since it's investing individual LUTs to things that can be only a few transistors in an ASIC.
@vertigo What I mean is that the current state of affairs makes every industrially-made CPU suspectful. Especially those made in countries with governments known for spying on citizens wholesale, who attempted to build the Clipper chip in the past.
I'm wondering how far we can go building these systems really from scratch. We still depend on Xilinx or Altera/Intel at some point anyway.
I'm curious about your point of view on these matters.
