How to use PDNSIM in OPenRoad-flow-scripts

[Coin-Hou]

The Makefile doesn't include the code for PDNSIM, please help.

Thanks for the reply. For my first time using OpenROAD, I still have trouble executing PDNSim on asap7 tech. The code stopped before outputting the results with lots of warnings about [unconnected instance]. I think maybe there's something wrong with reading the .lef/.lib profile. Anyway, my codes work for Nangate45/SKY130 but not for asap7, although they are similar.

There was an issue with asap7 pdn configuration fixed recently (dda86f6) . Are you using the latest ORFS?

If you are a test case would be helpful.
