wafer.space Community - Let me know if there is any problems

Thanks for sharing the repository! I'm currently trying to build the project. Just to confirm, I first need to implement the example_project by going into example_project and running make project, right? Ciel will then fetch the PDK that is marked supported by LibreLane. However I get stuck at GlobalPlacement:

Iter   |    Area   | Removed | Inserted |   Pins
|           | Buffers | Buffers  | Remaining
-------------------------------------------------------
0 |     +0.0% |       0 |        0 |       468
46 |     +0.0% |       0 |        0 |       422

[CRITICAL RSZ-2008] buffering pin _545_/ZN: wire step options empty

Could it be that you implemented the example_project with a different version of LibreLane than in the nix-shell of this repository? If so - that would be great! Then I would have another reproducible for #8229, which is not related to the I/O pads.

I did have to switch librelane versions because of this issue in Global Placement!

I have to switch to the regular release of LL rather than the fork used for the template.

That's good to know! It might really be a regression in OpenROAD, then.
