11.1 Known Issue - Constraints Editor - Why does my Net Period constraint show "NA" for my clock

Description

In Constraints Editor, I do not see my clock requirement, which is related to a NET PERIOD constraint. The clock net column shows "NA". Does Constraints Editor support Net Period constraints?

解决方案

Constraints Editor does not detect Net Period constraints. In order to use Net Period constraints, you must manually add the constraint in the UCF.
