Unexplained ratsnest on Import/Logic

[mstamler]

I have imported a netlist from Orcad to Allegro using the Import/Logic command and there are many nets that appear to be connected OK but I get a large number of ratsnets notifications about a net that is 'unplanned. Attached is a sample. The trace seems OK. When I redraw the trace the error goes away. Any ideas here?

I don't know what this means.

Go to constraint Manager----Electrical constraint set-----NET------Wiring------Topology----Schedule----and from drop down select Clear Rat nest schedule for that net.

May be in your DSN file designer have set the routing topology i.e RATNEST_SCHEDULE
