How to separate the connection of source and bulk

    Hi all,
    I'm in the hit-kit. When I add a mos, and select the "Substrate
    Contact", the source and bulk are seems connected together by default.
    But in some analog design, I don't want that, I need to separate them.
    So how to do that?

    Thanks!

    Analog or digital doesn't matter, S=B is broken unless the only
    thing you build is inverters. :)

    I don't know what a "hit-kit" is, but for analog design you should
    be using 4-terminal symbols for your MOSFETs. (E.g., nmos4
    and pmos4 from analogLib).
