I have created a set of constraints for differential pairs in the 'Electrical Constraint Set', and established several sets of differential pairs. Whenever I right click and Analyze a set of differential pairs the boxes I am expecting to fill with 'Actual lengths' and 'Margin' for 'Uncoupled Length' and 'Static Phase' are instead just turning yellow and not being filled with any information. This function works on other designs, but does not on this one. Does anybody have any suggestions why this might be happening?
Thanks.
