I'm getting weird PDN stuff with my project
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.
and that co-ordinate is this:
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?
d
definitely yeah
m
it fails after PDN, so I add the -1 to pdn.tcl?
d
you don't need to add the -1: if it outright failed, it should've packaged it automatically
m
no it didn't
d
alright, can we connect tomorrow? i've had a long day
m
FYI, pdngen is in the middle of a rewrite from tcl to c++ which I hope will land next week.
@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
m
ok
I have the reproducible. @User what do you prefer?
@User - sure no worries
m
@User Please open an issue at attach it
m
ok
in openlane?
or openroad
m
OR is fine with a standalone reproducer
m
train me to do it well so I can improve the quality of your issues
m
The test case looks fine. The new c++ version doesn't have this issue but it does have a different one 🤷
