Unexplained ratsnest on Import/Logic
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?
