10.1 Constraints Editor - Unable to create constraints for EDIF project

Description

After creating an EDIF-based ISE project, I launch Constraints Editor and create several constraints. Upon saving the constraints, I receive the following message in the console: 

 

"ERROR:ConstraintsEditorC - Unable to create constraints."

Solution

To work around this, manually edit the UCF. 

 

This problem has been fixed in the latest 10.1 Service Pack available at:

The first service pack containing the fix is 10.1 Service Pack 1.
