Answer 1

By default Diamond toolchain will only allow you to run Lattice from inside ICEcube. To run it from command line (or in scripts) you'll need to set some environment variables. Here's what worked for me on Windows (with my version of Lattice toolchain):

$ source ./set_vars.sh $ICE_ROOT
$ $SIM syn/sim.do

(links to scripts: set_vars.sh, sim.do).
