Greetings, I was going through the opensource RTL to GDS flow using open lane for a simple PWM generator. However, I did not come across a tool for IR drop analysis in Open lane. Are there opensource tools available for IR drop analysis? If yes please suggest them here. Thanks.

e.g. opensource psm module in OpenROAD is a static IR drop analyzer, based on PDNSim: https://openroad.readthedocs.io/en/latest/main/src/psm/README.html

Great thanks! Will look into it
