OrCAD professional fanout etch tuning creating opened nets

tinyspud

Hi

I have a weird problem - I'm trying to work on timing a matched group with the relative propagation for the net group.  I did a fanout on my connector and every time I edit the etch the net that I edit the fanout gets modified in such a way that the connectivity gets broken at the pin on the connector that's fanned out.  I also can't see the GUI option that shows me the timing that I'm missing but I'm not sure if that's due to this being a broken net or if is an option I disabled before.

This is a design I've reused a few times so there's probably some stale rules that need to get flushed but this used to work (with the delay tuning tool giving me my +/- tolerances for the net to come up to the spec on the target) and it didn't used to disconnect the net whenever I edited the trace.

I'm using OrCAD professional 17.2

    Okay so what happened was the fanout got stale so I redid the fanout on those pins, ran the DB checker and it deleted the redundant vias and now everything seems to work just fine
