Optimized design "vopt_tb" cannot be used by this version

[cyberbemon]

There are a couple of independent problems here.

- It seems like you used vopt (which is one part of compilation process you have done) using a 32bit version and then are trying to start the simulator (vsim) using a 64bit version. At least the error suggests that. This should be on your end, not an issue on the PULP part.

Thanks, that was the issue. I had one too many environment variables that pointed to 2 different versions of modelsim. I changed them to point to the correct version and I can get things to compile.
