AR# 32843

11.1 Constraints Editor - Option of deselecting the reference timespec is not available in the table

Description

There is an option of specifying a PERIOD Constraint as a reference of another PERIOD Constraint, but I am unable to modify the Reference Timespec back to Explicit TimeSpec in the Constraints Editor GUI.  

 

Is this a known issue?

Solution

This is a known issue that is scheduled to be fixed in the next quarterly release of ISE (11.3). 

 

In the meantime, to work around this problem, modify the constraints manually.
