Actual Value in Allegro Constraint Manager

HirosakiOnda

Hi guys,

I have a problem that when I created the T-point in a net schedule. Then in Constraint Manager, I created the pin pair in Electrical Tag, I choose 2 T-points and Apply, the Allegro tool also display like as:

After I selected OK, I set up a value and the ACTUAL VALUE like as:

I see only yellow color and have no value at there,   [=> I want to see the ACTUAL VALUE and MARGIN]. Please help me. 

Thanks so much!

Best Regards.

    So the issue is that the constraint is not enabled. A Yellow column header is a big clue here. Go to Analyze - Analysis Modes - Electrical and turn on the DRC mode for Prop delay and the actual values will show if routed. if they are unrouted you can also enable DRC unrouted which would show values based on the manhattan length.
