cshunt equivalent in spectre?

    I am trying to find out if there is an equivalent way of enabling the
    HSPICE

    ..option cshunt=xx

    in Spectre. I've tried converting an HSPICE file to a Spectre file
    using spp -convert, but have not been successful.

    Chris:
    In the transient options there is a parameter called cmin.

    When cmin is set to a nonzero value it connects a capacitor from every
    node to ground.

    Thanks Erik. I forgot to specify that I am doing AC simulations, not
    transient sims. I find that my PSRR simulations vary greatly if I
    include wireload capacitance on the nodes using HSPICE and test over
    all corners. I was wondering if there is a way to duplicate this in
    Spectre.
