I can't say anything about the question you asked, but I can say that
I bought the entry level design package for Lattice since they don't
have a free version that can actually be used for work like Xilinx and
Altera do. I ordered the package that included ModelSim and that was
good for me since that is the only simulator I have used. But between
the time I sent in the order and the time when I licensed the tool,
they changed their agreements and started providing ActiveHDL! I
complained loudly but they would not provide a license for the tool I
had and would only send me the software for the new tool. So I gave
it a try and have hardly looked back.
My point is that it is very easy to switch and I am totally happy with
ActiveHDL. I can't think of anything about that I don't like other
than possibly the way it wants to create its own structure for your
files, but I finally figured out how to keep it from copying the
source files to it's own directory. I still don't know what the
difference between a design and a "workspace" is, but the Lattice
version only allows one design to a workspace. I don't seem to be
limited by that.
