Tools for viewing the analysis of Impedance vs Frequency performance of Power Ra

[Freshman]

I noticed that there are a few online tools/plotters that are there for Power Delivery Network analysis. They show the impedance profile (Impedance vs Frequency graph) for the power rails after providing the capacitor value inputs and the stackup related information.

However, I noticed that some ECAD tools like Altium designer have the power delivery network analysis (PDN Analyzer). But they don't provide us with the plots of Impedance vs Frequency of the rail with the capacitor inputs and PCB stack-up information.

I searched but couldn't find a tool that can provide the impedance vs frequency plots. Any idea on what CAD tools that I could use to view these impedance profile plots?
