The guide looks to be very close to a macro where you can't legally drop a via. @eder-matheus any thoughts on the guide?

Yeah, they look too close to the macro. I'll try the macro extension option to see if it resolves and will investigate how to improve our resource modeling to avoid such guides so near the macros.

@oharboe Can you add a reproducible of this issue? Having only the final ODB for the routing will not be enough for debugging the global routing of this design.

@eder-matheus I think you fixed this?
