Prerequisites for Using the Layout XL Connectivity Extractor

Prerequisites for Using the Layout XL Connectivity Extractor

If you are using the Layout XL Connectivity Extractor, you must define a virtuosoDefaultExtractorSetup constraint group. For example,

constraintGroups(
 ; ( group                             [override] )
 ; ( -----                              --------  )
   ( "virtuosoDefaultExtractorSetup"    nil
   ;  layer constraints
      interconnect(
      ( validLayers    ( Nwell Oxide Nimp Pimp Poly Cont Metal1 Via1 Metall2
      Via2 Metal3 )   )
      );interconnect
     );virtuosoDefaultExtractorSetup
);constraintGroups

Layout XL issues message LX-2063 if the constraint group is not defined appropriately.
