Shabaz,
Google "Books on Signal Integrity", and "Books on Power Integrity".  Signal
Integrity/Power Integrity are fields of study that require a great deal of
time and effort on the part of the practitioner.  There is no simple answer
to your question.  Best to start reading right away.

Hi Experts,

What does it means by power plane impedance while doing Power Integrity
analysis.

The power plane impedance is kept at mili ohms for a wide range of
frequencies for better PI.

Kindly guide me

1. what does it means by power plane impedance?
2. what should be its nominal value?
3. For better PI, should its value be as small as possible like 2mOhms?
4. if yes? what is the reason.


Thanks In advance. I am new to SI and PI


Thanks,
