Nets in the PCB layout not respecting the spacing rules provided in the constraint manager

RohitRohan
RohitRohan over 1 year ago

When i am routing the nets in the PCB board i can see that the nets which i routing in the PCB board are not respecting the spacing rules provided in constraint manager. The 2 nets come close to each other normally they should shove, but in case the PCB board which i working, the 2 nets even though different net names when the nets come close to each other instead of shove the nets are overlapping to each to other. In analysis the spacing constraints are enabled but still the nets are overlapping with each other. May i know why the issue is occurring. I have run the DB Doctor also on the PCB file but same results. Currently i am using version 22.1 PCB editor.

    Do you see any DRC errors where they cross? Does this happen on every design you have? I would probably need to see a board file to debug this any further so maybe raise the issue with Cadence/Channel Partner direct so they can get the actual board file.
