Along the lines of the question regarding LTspice logic levels...
PSpice has a number of nice digital stimulus "parts", but they kick
out _very_fast_ edges at 0-5V logic levels when connected to analog
parts.
So, in this past week, I have created some stimulus-level-to-analog
parts with adjustable levels and rise and fall.
Likewise analog back to 5V logic.
That way I can patch in 74HC stuff just for behavioral analysis...
speeds things up before I go full device-level in the chip design.
Any PSpice users that are interested, I'll send you copies for your
symbol libraries... PSpice Schematics only... Capture sucks the big
lemon ;-)
