The Quickening

“Project IceStorm aims at reverse engineering and documenting the bitstream format of Lattice iCE40 FPGAs and providing simple tools for analyzing and creating bitstream files. The IceStorm flow (Yosys, Arachne-pnr, and IceStorm) is a fully open source Verilog-to-Bitstream flow for iCE40 FPGAs. “
