What's Good About Formulas in Allegro Constraint Manager? See For Yourself in SPB16.3!
Since the initial release of Advanced Constraints, one of limitations was that formulas had to be recalculated manually. This recalculation could be done on an individual basis or for the entire design with the Calculate All command. The Online Formula Calculation feature addresses these limitations...
