PDN frequency target

Dear All,

I was wondering if someone could suggest a way to extimate the maximun frequenzy (f target) up to a PDN impedance should be kept under a certain level (z target).

According to Dr. Bogatin's brilliant book "si e pi integrity - semplified" chapter 13 has been suggested that 100 Mhz should be fine if not otherwise specify, but i would like to been able to find out this limit on my own.

From the ibis the parameter L_pkg shouldn't be very usefull because seems to rapresent only a partial inductance (am i right?).

Any idea?
