Orcad has no "concept" of an XNET. This is a pain. We ended up only being able to put properties on the input or the output of a series resistor or cap. There is a good little paper available on this problem. http://www.alspcb.com/pdfs/OrCAD_xNets.pdf and the problems of maintaining and linking netlists. Hope this helps.

Which constraints can NOT be passed from Orcad to Allegro that ConceptHDL easily passes? Thanks for any info - we're trying to decide whether or not to switch from Orcad to Concept, and I'm not finding many advantages to the switch so far. Thanks.
