Measurement of ground bounce and impedance of RLC network

sazjad
Hi all, 

I am trying to measure the effect of power gating on the substrate noise. In other words, I want to measure the amount of ground bounce through SPICE simulation. Initially, I am planning to use lumped RLC model (attached picture) to mimic the ground network. 

Now I have two questions: 

1) Is that the correct approach to measure the ground bounce? If not what are the methods/metrics I should use? 

2) I also want to measure the impedance of the power distribution network using this lumped RLC model for different switching activity of load circuits. I am not quite sure how to achieve this. For example: how can I get impedance vs frequency characteristics using the lumped RLC model I am using? 

Please let me know if you have any question. 

Thank you for your time and help.
