cshunt equivalent in spectre?

[Chris Price]

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.
