@User can you help me on this if possible.. I want to generate IR drop for PDN... Is https://github.com/The-OpenROAD-Project/PDNSim this simulator integrated with OpenLane flow scripts? How to install this with our local machine? I am getting below error ============================ -- Detecting CXX compile features - done CMake Error at CMakeLists.txt:32 (add_subdirectory):   The source directory     /home/vijayan/OPEN_LANE_FLOW/Power_Domain_Network/PDNSim/modules/OpenDB   does not contain a CMakeLists.txt file. =====================================
