    Analog Layout and Dummies

    Hello,

    I am doing Analog CMOS Layout and add dummies to my layouts.

    Do I need to put them in the schematic view in order to pass LVS or is passing DRC good enough ?

    What is the proper procedure ??

    Thank you.

    Of course. Your schematic must fully comply with the layout. DRC will go well and without adding these elements, because this procedure only checks your topology, the correctness of the technological distances. LVS (Layout versus schematic) checks the compliance of the layout to schematics.

    "Pruning" rules might take out properly tied off dummies,
    but schematically representing what you laid out, as you
    laid it out, has no such dependencies.

    I think only half dummies need to put in schematic. Fully dummies is already tied off and no need to put in schematic.
