*WARNING* (LCE-2066): Constraint 'validLayers' in constraint group 'virtuosoDefaultExtractorSetup' of technology 'tcbn28hpcplusbwp7t30p140' contains a diffusion layer 'OD' and a poly layer 'PO' but no derived layer indicating that the diffusion layer is stopped by the poly layer. This incomplete setup can result in incorrect short markers. For accurate connectivity extraction, add an appropriate derived layer to the constraint.
