Is there a particular resolution for this?

[delaram-mz]

@kareefardi I'm having the same issue, did you find any solution to fix this?

[maliberty]

FYI, OR doesn't support CCS currently. Perhaps this is for use in another tool?

[kareefardi]

@maliberty These are just coming from the PDK without them targeting a specific tool. However, I do think that the warning by OpenROAD is correct and it should be fixed in the PDK file.

@delaram-mz No fix a the moment. They are just warnings and don't cause errors. However, they are noisy and we can attempt to handle them.
