    What variety of Spice?

    Specific trip levels or generic?

    Speed of operation?

    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.
