Please package a standalone test case.

Sorry,sir. I think It's hard to isolate a test case because I try it under the Chipyard framework. Tutorial:https://chipyard.readthedocs.io/en/1.13.0/VLSI/Sky130-OpenROAD-Tutorial.html I wander how to find the problem,when you face this kind of problem in openroad?-----how to correct the violation of li1 and met1 or ignore the violations----- I'll try to locate the relevant configuration files.
Thank you very much.

Taking a peak at the docs it looks they expect:

OpenROAD v2.0-7070-g0264023b6 (place-and-route), install [using conda](https://anaconda.org/litex-hub/openroad) (note that GUI is disabled in conda package) or [from source](https://github.com/The-OpenROAD-Project/OpenROAD/blob/master/docs/user/Build.md) (git hash:

which would be an extremely old version of openroad

March 2023! Without seeing a test case I have no idea what the issue is or how to resolve it. It is not a problem normally seen elsewhere.
