I called it by the wrong name. That will be VERY useful... THANKS!

No Problem!

Just remember that this uses the standard stim set up in digio.lib, so
it is typically 0-5v, and goes up to about 2Ghz reliably.

Also, the Z is what is set up in your digital options, so if you need a
really high Z (the default IIRC is only 10K) you need to change your
options.

Hi Charlie,

Looks like the library is actually named "dig_io.lib" ;-)

I find "Z" is 1Meg in most logic families, but 200K in TTL.

I couldn't find "Z" defined in relationship to "STIM1"

Where is that set?

In your sim options, it is called DIGDRVZ, and on my version defaults to 20K

Usually an advanced digital option.

Is that available readily to those of us still following the true
faith (AKA MicroSim PSpice Schematics) ?:-)

Aha! Found it right there in the plain vanilla Options settings.

Is there a way to set Options to always be the values I want, and to
always appear as the defaults?

Hi Jim,
Not really. You can always create a .inc file with the options set the way
you want.

Or wait, can you set them in the pspice.ini file? No, I guess not. In
Capture, you can now import a standard simulation profile... 8-)

Or get a substitute with a MicroSim-Schematics-like front-end...

But I guess you are right... just do a .INC*

Any advantage of .INC* versus .LIB*

Include files add all the lines into the netlist. A library only adds
