I have a via with netname VBAT. I have a dynamic shape on the same layer. When I route from the via and stop in the shape area and end the route the netname changes to the name of the shape. How do I stop this from happening ?
Net Name of Vias are normally inherited by a Pin or Shape and there is no guarantee it will remain connected to the expected net. A good rule of thumb is to make sure the Via finds its way back to a Pin…
What net is assigned to the shape & is it the same as VBAT.
I have never seen Allegro just changing a net name on the fly. This would go against every rule one would expect from a host cad system.
Seems odd you are seeing this. If the net name for the shape was VBAT then one would expect a merge as the nets are the same. If not the dynamic shape should clear to make way for the VBAT route.
Net Name of Vias are normally inherited by a Pin or Shape and there is no guarantee it will remain connected to the expected net. A good rule of thumb is to make sure the Via finds its way back to a Pin using a Cline connection to ensure that it maintains the Net with attaching the Via to a Static Shape a close second.
Another option is to add the Property RETAIN_NET_ON_VIAS on the Net so its attached Vias don't easily jump to a different net.
Hope this helps, Mike Catrambone
