Yes, but a designed-for-FPGA SHA256 implementation looks very different than an ASIC SHA256 implementation - the ASIC has far greater routing flexibility and density, and can therefore use far more combinatorial logic between register stages.
(ASIC simulation on an FPGA will retain the combinatorial stages but run at dramatically lower fMax)
- benlivengood 1y agoI should have been a little clearer. I meant that the miners spent a brief period optimizing FPGAs before they abandoned them entirely for ASICs, but during that brief period I'm guessing they squeezed as many hashes/watt out of the FPGAs as they could.
