Copy code
INFO PSM-0064] Number of voltage sources = 88.
[WARNING PSM-0038] Unconnected PDN node on net vccd1 at location (367.200um, 1910.580um), layer: 6.
[WARNING PSM-0038] Unconnected PDN node on net vccd1 at location (367.200um, 1910.000um), layer: 5.
[ERROR]: PDN generation failed.I also have this
repo is here - should fail fast with make user_project_wrapper
any thoughts @User @User? should I try to make the reproducable and open an issue?

03/16/2022, 7:57 PMyou don't need to add the -1: if it outright failed, it should've packaged it automatically

@User in your "I also have this" it is likely to be a repair strap in a channel between macros. If not that would be of interest
