What variety of Spice?

Specific trip levels or generic?

Speed of operation?

And are only rude and interruptive.
Lack of mental capacity?

PSpice 9.1 Student, preferably.
But if needed, I have SuperSpice.

Generic.

I don't know about this.

For a totally programmable Schmitt trigger, see "EasySchmitt.pdf" on
the S.E.D/Schematic page of my website.

I don't know if the Student version will do the NANDs. If not,
replace with your typical S-R-Flop made from NPNs.

Of course, XSpice has a configurable standard inbuilt part, i.e. one
with essentially, zero evaluation time, when compared to say, a diode.
