We recently purchased the V-System/PC compiler.  I don't think the windows
version is available yet.

From the Technical Description from Model Technology:
"System Capacity
  Depending on the code, you can expect at least 1000 lines before
  the 640K PC memory limit is reached.  If the whole design is modeled
  at the structural level, designs of around 300 gates are possible."

So if you plan on simulating the 386 at the gate level, you probably
will run out of memory.  :-)

(The Windows version will not have the 640 K limit)

I really didn't spend enough time with the system to get a good feeling
about all its capabilities.  The system is not 100% VHDL compatible; some
code that I have been using with the Intermetrics VHDL system would not
work on the PC.  In a few weeks, I may be able to tell you more.
