List of files needed to rerun Aldec simulation?
The only files I check into my repositories are the VHDL source plus benches and adf files.  All the others are automatically created.

I just add the adf files to a new workspace.  I always put the VHDL source in a src folder in the same folder as the adf file.

I can't recall what files define the waveform view if you want to preserve that too. Aldec changed their waveform viewer (for the worst IMO) and I've not used it much since as I've not worked in a place lucky enough to own it.
