Plotting PDN Profile - Decouple Wizard

Hello,

 

I am using  Decouple Wizard to plote a PDN lumped profile.

 

Settings:

 

1. Loaded Board's HYP file in BoardSim

2. Lumped Analysis 

 

Z profile is attached. It shows a  capacitive Z profile at the low frequency band -  below 100 kHz.This is confusing. In this range I would expect to see a somewhat  flat prifile mostly corresponding to  an internal VRM resistance. However, there is no VRM selection  under Lumped Analysis.
