    BAD_SUBSTR_SUBTAP_FLOAT_ERC in pmos with ams 0.35

    HI
    I have a problem with virtuoso and AMS 0.35

    De assura DRC indicates BAD_SUBSTR_SUBTAP_FLOAT_ERC but I think the substrate is well fed to VDD

    thanks.

    PMOS n-well is connected to the vdd, but the error is related to lack of a ground connection to the substrate!
