Canes,
Try to use pkg parasitic values from a pkg similar to what you are
thinking of using for doing your initial simulations. If you are way off
on your pin count then you will need to move to a different pkg.=20

Subject: [SI-LIST] SSO doubt
hi,
I could see the SSO results strongly depends on the package parasitics,
esp. Inductance.
We are in the process of selecting the package, die size etc. Even
though we fixed the number of pins for the package, we are still in the
process of finding the split-up of power and signal pins.=20
But for deciding number of power /signal pins, we need to do SSO
simulation, which again depends on package parasitics.=20
For example, if I go with say around 2nH as the package inductance I
could get the pin count as spec.
But if I go to say 10nH, its exceeding the spec heavily.
How to solve this chicken-egg problem?=20
Please correct me if I'm wrong in the system approach.
Regards
Canes
