Cadence Virtuoso Post-layout simulation using Calibre

[presun]

Hi I am currently designing a two stage opamp and I am doing post simulation, I have a few questions as I am going through the post simulation.

1. even if I apply VDD to the actual pad, the VDD coming into the circuit is bound to have a slight voltage drop, is there any way to check this?
(I have a picture of the layout in the attachment).

2. in post simulation, I would like to see the current flowing through each stage, but I don't know how to do that.
(Currently, I can only measure the current flowing from VDD (sum of the current flowing from 1st and 2nd stage).

1. The first thing you can do is to measure point-to-point resistance using Calibre PEX RVE and calculate the voltage drop yourself. More complicated approach would be to run IR analysis, and then check the heatmap of the results.
2. I think that the easiest way would be to annotate operating points of your devices (DC or train) by using View -> Annotations after your simulation with extraction is completed.
Hopefully, that helps.
