Don't know about match but I can guess the NPN.tol as I have something similar in SS. My bet is that the NPN.tol IS=0.75 BF=.9 gives the amount to vary the base model in worst case and/or MC runs. The "match" probably allows two of the same devices to be varied by the associate value, e.g. one device's IS in 3% different from another.

SuperSpice, a very affordable Mixed-Mode Windows Simulator with Schematic Capture, Waveform Display, FFT's and Filter Design.
The above are *defaults* for all biploars. However, In addition, you can also specify a specific model variation spec for a particular device by naming the model spec location in the actual model, e.g:

I love to cook with wine. Sometimes I even put it in the food.
I can't find the part that tells why to use breakout parts. What's the deal on that?
I see that in PSpice, *it says* that for 2 parts with DEV=5%, one can go up 5% while the other goes down 5%, but in the SIMetrix manual it says they'll be within 5% of each other. Typo? Confusion? Different implementations?
Sorry, I wasn't very complete, I just plunked down a sample model from Semtech, the ONLY foundry I use that expresses model variations in Monte Carlo style, rather than with library corners.
I don't know what version you have, but I've posted, from my version
10.0....
Newsgroups: alt.binaries.schematics.electronic Subject: Monte Carlo Models (from sci.electronics.cad - MonteCarloPSpice.pdf Message-ID:
The PDF posted is the model section from the PSpice reference manual, version 10.0, showing notation for Monte Carlo parameter stepping in PSpice device models.
I just received version 10.3, but won't have time to install until next week... I'm in my usual crash and burn mode ;-)

Security in PDFs is pretty much meaningless as long as they allow printing. Just print to a PostScript file, then run thru Distiller.

Unfortunately apps writers are often not USERS :-(
I keep finding capabilities in PSpice that the support people don't know about ;-)

I've not experienced that. I've had a few with security set, so I couldn't do the standard "extract pages", but I could still print to PS and then distill (v4).

I belive that Distiller will refuse to do its thing when presented with postscript derrived from an encrypted PDF. There may be other tools out there of course...
No Jim, Why should that be? While the AEs work around the product all day, they don't actually get to do much USING the product that much, so that, when they get an actual design problem, they tend to over-prioritize it... 8-)
So, you do a lot more with it than they do...
Also, it helps that you push the envelope a lot!
