I'm PSpice's biggest critic.

What's your opinion on how close LTSpice is to being ready for prime time?
I'm guessing it lacks support for BSIM models, which I would imagine is a
non-starter for you.

I haven't tried but just a few things with LTspice, though it seems
pretty robust. Actually I believe it does support BSIM3, but I'm not
sure.

I'm not fond of its output GUI, and I'm REALLY fond of PSpice
Schematics, so it's hard to pull me over ;-)


As for overlaying multiple simulator runs on top of each other I have
a trick...

Yes, and it's a good trick; I just still consider it a lot harder than it
should be -- other simulators I've used (such as SIMetrix) by default overlay
all subsequent runs, and if/when you get sick of that you can specify each
probe to have a "persistance" over a specified number of runs (e.g., setting
it to 1 makes it behave like PSpice, I find it often useful to see the last
2-3 runs).

There's several other ploys in PSpice...

(1) Edit the *.CIR file to contain multiple runs, then the Probe
output will be overlaid

(2) Save each run under a different name, then "Append" those DAT
files.
