Now that you mention it ...  A little bit extra adds up.  One 
more int, 4 bytes, is 4 megs.  It won't do it with BSIM3 
models, but I said "real switch level models" are needed.

I am working on some database changes to move elsewhere the 
space used by the analysis.  This should help.  Then the space 
will only be used when you do the analysis that uses it.  If 
you will contribute the switch level part, I will raise the 
priority of the rearrangement of the data structures.

That's probably what you want.

Starsim? really?  for over 1M transistors?

I think it is really a bunch of little simulators hiding under a 
shell.

Of course.  What do you expect?
