One thing I have noticed is that fasm2frames takes a possibly avoidable long time to produce the frames file. As an example, the baselitex test takes ~1minute to compute the frames file.

I believe this run-time could be cut down by refactoring fasm2frames (maybe to a compiled language?).

First thing to do would be profiling where run-time is spent.

I think the library used for FASM parsing (textx) is probably not scaling well enough.

This should be resolved by chipsalliance/fasm#28.
