PSpice Netlisting/Template Trick

Just discovered (or re-remembered :-), in PSpice...

To just have the color of an LED showing in the schematic (I hate over-klutzy drawings), I just enter color and the template collects the model name...

Template= X^@refdes %1 %2 My\@COLOR\@LED COLOR=RED LED=LED ...Jim Thompson

Sounds like you're simulating my "LED differential pair" circuit.

It works, doesn't it.

That simulation takes a loooong time to run. Mikek :-)

"Sounds like"??? The netlist I provided is that of the PSpice schematic I published earlier...

Message-ID:

Where I PATCHED Larkin's not-so-well-thought-out circuit, then ran it both on PSpice and LTspice.

The reason is takes a "loooong time to run" in LTspice has nothing to do with run time, but is all about the poor library handling in LTspice. Watch the message tray in LTspice to see what is happening. I posted a separate message addressing this library (mis)behavior. ...Jim Thompson

Hi Jim, I don't have a clue if it really takes a long time to run. I was just picking on you, Larkin tried to drag you into an argument and it had been 4 days with no response. Guess you were just being the bigger man. Good job! Mikek

Actually it seems to... but all the excess time is taken up by loading my library, which is extensive. PSpice scans an index, loads only the location of the components used, then runs. LTspice checked _every_ component in my library, then barfed because a component not even being used by the schematic, had a syntax LTspice didn't understand... like my digital behavioral stuff. So I had to pare down MyLib.lib to MyLibLTC.lib, containing only LTC-syntax-compatible components. It's still "slow" because of LTspice checking _every_ component.

Maybe I can figure out a trick to get around that... like create a schematic-specific library on the fly

Thanks! ...Jim Thompson

Aha! Solution right under my nose... PSpice has a compression utility that "packages" _only_ the needed components and models. (Conceived originally to allow passing a schematic to another PSpice user, who has his own symbols and models.)

So, a little klutzy, but it'll work... compress, uncompress, and the .CIR file will now library only the required components.

Thus I can address quickly circuit questions that come up here, by doing my solutions in PSpice, but conveying the content easily to the LTspice user. ...Jim Thompson
