[SI-LIST] Spectre S-parameter based PDN simulations

Hello All,

I am trying to set up a PDN simulation in Cadence Spectre. The PDN
includes S-parameters of the package and some RLC models for the
decoupling caps (PCB,package) and VRM. I can use this network to do
AC/S-parameter analysis without any trouble but when I include this
network along with the die model in transient simulations, the voltage
node supplying the die blows up. 

I have tried to look in the Cadence Sourcelink database and also tried
the various options available in the N-port properties dialog box to no
avail.

I was wondering if anyone out there has faced this problem with Spectre
and solved it? If yes, could you please give me some pointers on the
same.

Thanks very much. 

Best Regards,

Suresh Subramaniam
