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 focus of the project is on the iCE40 1K and
-8K chips. (Most of the work was done on HX1K-TQ144 and HX8K-CT256 parts.)
