We are currently using rel 16.3 and getting ready to transition to rel 16.6. We use both Concept HDL and Allegro. However we create and maintain our constraints in Allegro only. Therefore Concept is not "constraint manager enabled". Starting with rel 16.5, constraint manager is enabled by default. So net properties will be transferred back to the schematic during back-annotation. Is there any way to prevent that? Exclusion in "Projmgr -> Setup -> Packager XL -> Property Flow Setup" does not work well.
