Have you tried opening Pspice schematics in LTspice? Try it and report back what happens. :)
Pspice to LTSpice/SwitcherCad schematic conversion?
Apr 30, 2005
6 Replies
I'm rather new to using switchercad (I know, after years of it being mentioned here just about every day) but like the similation, but not the schematic entry user interface. I've got some schematics I've entered in Pspice Student version I'd like to simulate on Switchercad but don't like the idea of entering them a second time, especially in Switchercad's UI. Is there some utility that will convert schematics from Pspice to Switchercad?

LTSpice will read and run the PSpice netlists directly. Just open it in LTSpice

SuperSpice, a very affordable Mixed-Mode Windows Simulator with Schematic Capture, Waveform Display, FFT's and Filter Design.
Cute! I can now post some of my stuff in LTspice form!
However I couldn't figure out how to descend into a hierarchical block.
I opened a v10.3 schematic... keeping in mind, for the youngsters, I still use Schematics, which is still the old original MicroSim marvel. I DON'T USE OrCAD Capture (gag me with a spoon :)

I love to cook with wine. Sometimes I even put it in the food.

Hallo "analog",
Thanks for this reminder. I had forgotten that I heared of it. Now I tried it a few minutes ago with "example.sch" and I am deeply impressed! This has been a schematics from PSPICE 8.0. Ok, there is still a lot of manually rework necessary if it has to look professional, but it's a great starting point. I assume it only works with PSPICE8.0 schematics.
Be aware to know where your PSPICE ini-file is located. Most probably it's "C:\windows\msim_eval.ini" . I am not sure how this file is named for the full version. Maybe it's "psice.ini" or "msim.ini".
It's an undocumented feature. So we don't know that it will be forever in LTspice.
Best regards, Helmut
PS: I am not an employee of LT if that matters.
LTspice/SwitcherCAD III is free SPICE with graphical user interface.

There is an independent user group for LTspice.

This might not be a good thing... 8-)

Wait and see.
