Lattice Diamond was Written in Crayon

I have spent about a day trying to coax Lattice Diamond in to programming a Mach OX3. Maybe the Windows version is useable but really Windows, no thanks I’m working here. The upshot is this: if you need anything outside the ice40 series–for which there are open source tools that one can find by searching IceStorm–then it’s time to move on to Xilinx or Altera. Quartus uses a version of Synopsys and, more to the point, it is usable.
