Matt Venn
10/27/2021, 6:56 AMmaybe it's there but you're not seeing it
Matt Venn
10/27/2021, 6:57 AMdoes it work with the original configuration (the example project)?

Aireen Amir Jalal
10/27/2021, 6:58 AMYes met5 is on

Matt Venn
10/27/2021, 6:59 AMI would try the example project with the default configuration and see what happens

10/27/2021, 6:59 AMthere was recently an issue wrt pdn, where they moved the file from open_pdk to openlane
Matt Venn
10/27/2021, 7:00 AMso it could also be you have a mismatched setup with an old openlane
Matt Venn
10/27/2021, 7:00 AMbut it's clear you have some of the pdn working

10/27/2021, 7:39 AMThe example project's pdn works fine.

10/27/2021, 7:39 AMI'd compare the results now to see what the problem is..

10/27/2021, 11:27 AMFound the problem! I used routing obstructions of metal5 while hardening my design, which are restricting the metal5 rails to go over the macro during wrapper hardening. Just for the sake of testing, I commented the Obs layer of metal5 in my macro lef and the problem solved. I would now reharden my design by defining the max routing layer to go till metal4 rather than applying obstructions.
