We have enough bits mapped that we can create a functional verilog model for almost all -bitstreams generated by Lattice iCEcube2 for the iCE40 HX1K-TQ144, as long as no -block memories or PLLs are used. (Both are fully documented, but the -icebox_vlog.py script does not create verilog models for them yet.) -
