PDN file and PCB decoupling

Hello,

In the PDN excel file how is determined the ESR and ESL value for the decoupling capacitor ?
I would like to add bigger capacitor .
Is there some explanation for this file ? all the cells are locked.
Is there some explanation to help to determine the number of capacitor needed for an application.
I put the power rail voltage and current and now I need to determine the capacitor decoupling for each rail.

I'm using a 5CEFA4_M13 chip on my board.

Thanks for your help
