This issue needs to be resolved or waived before tapeout.

Some of the power nets that are unused in user_project_wrapper do not match the connections to caravel chip_io.
| chip_io | user_project_wrapper |
|---|---|
| vssa1_core | vssd2 |
| vssd2_core | vdda1 |
| vdda1_core | vdda2 |
| vdda2_core | vssa1 |
These nets are not actually used in user_project_wrapper, so relabeling would be sufficient.

We need to check if it impacts other projects.

@d-m-bailey I was looking at the pdn and looks like you are highlighting the wrong net, vssd2 is the 5th ring from the right, not the third
