Hello all,

In designing PDN (chip-pkg-board), many people do frequency domain  
analysis to determine the impedance of the PDN. What is it for? As far  
as power integrity is concerned, isn't it better and enough to run  
transient simulation to see the PWR/GND bounce seen from the chip e.g.  
I/O ?

Many thanks,
Jenni
