Honored ContributorYou can't, timequest is aware that the node is connected to a clock input of a flip-flop. So you have two choices:
1 - If the node is timing criticial, you can constrain it appropriately and tell timequest to analyze it as part of the data path. 2 - If the node is not timing critical, ignore it. Timequest will list it as an unconstrained clock but that's it, no harm done. Jake
