It would probably be a bad idea to trust the results of IRSIM to the
point that the exact values in a .prm file make a difference to the
simulation.  If you are using, for example, reasonably well-designed
standard cells, you should be able to generate a .prm file with decent
values.  Nevertheless, you probably want the most accurate values you
can get, and it's not an unreasonable request.

I looked at the set of .prm files available from Jeff Sondeen and most
of these have only a few useful values in them, far from being
comprehensive.

The worst thing is that I don't know of any documentation describing
what values can go into an IRSIM .prm file, what they mean, or what
values they take.  With that information, it's reasonably easy to fill
in a few values from the process electrical parameters manual.

I will try to write up a complete description of the .prm file format
over the weekend and post it on the opencircuitdesign web page for
IRSIM.  I am also CC'ing this message to the magic-dev group in case
anybody reading it knows of any documentation covering the .prm file
format.
