After running make user_project_wrapper, I get the following warning. [WARNING]: All internal macros will not be connected to power. Does this look problematic? and if so what could be the root of the problem?

@User Sounds like this problem. https://skywater-pdk.slack.com/archives/C016G7Z8GDR/p1640693345183700 Does this help?

So if I just set FP_PDN_MACRO_HOOKS to 1 in the user_project_wraper config.tcl, everything should be fine? or do all my macros need vccd1 and vssd1 signals?

I always see this too, but i have checked the pdn many times and can see they are powered

ok, thanks.

Worth inspecting the pdn tho

I am not really sure how to do that

Load pdn def with klayout

I used find *pdn.def

You should see metal5 going across your macros and via4 dropping down to the pdn of each macro

ah found them

If there was a problem tho, the flow would have failed on lvs

If I get this correctly, the error message is misleading. From what I can tell it should be "Uh, I've been generating one of the four power networks, and I've noticed that nothing is connected to it. I hope that this is right". For designs hooking everything to the same power network, the warning should then occur exactly three times. At least this is my interpretation. 😀

I think I forgot to connect the macros to power in the FP_PDN_MACRO_HOOKS parameter in the user_project_wrapper config.tcl, I am running the flow now. hopefully it will come out ok
