Wow Clifford is that you ? I hope this, exciting as it may be, won't make you leave open fpga efforts for the dark side (saw your talk last Fosdem, was very exciting)
Cotton is the author of arachne-pnr. Clifford is the author of Yosys and IceStorm, which are all separate projects. Not the same person.
FWIW, Clifford has recently started reversing the bits of the modern Xilinx FPGA series. So, stay tuned for a Xilinx IceStorm-equivalent sometime down the road (a few years, probably...)
No, Clifford is cliffordvienna on HN. He wrote Yosys (and amazing piece of software) and did the iCE40 reverse engineering (amazing work). I wrote the place and router, arachne-pnr.
