  Why would someone use this vs Rocket/BOOM? Is it compatible with cheaper FPGAs?

  Presentation that includes size and performance figures:

  Summary: smaller and faster than PicoRV32 & Z-scale, slower but smaller than Nios II/f.

  Any idea why it performs so bad on ice40?

  Given that ice40 is the only (unofficially) open source FPGA, I had high hopes for the architecture...

  Would be nice to see a change log.
