Is there a way to fix the target net in propagation delay?

avant

I set clock nets as targets in relative propagation delay work sheet.

While reviewing, the target nets changed. Is there a way to fix the target?

    Yes - In the Delta:Tolerance cell for the net right click - Set as Target

    Yes, I set the target, but somehow the target net changed to another net.

    This happened on four busses that I had set the clocks as the target nets.

    Could be hotfix related so make sure you are running the latest version, 17.4-2019 S030 or 17.2-2016 S083

    The role of delta & tolerance is still confusing. When delta is set 0, the results will be different, when it set to nil the results are different. Aren't zero & nil value play same role ? It would be great if anyone could brief out delta & tolerance role.
