10.1 Constraints Editor/Floorplan Editor - Launching Floorplan Editor after Constraints Editor is Up causes Project Navigator to crash, ConstraintSystem:151

Description

After making some timing constraint changes in Constraints Editor, I launch Floorplan Editor to make some physical constraint changes, NGDBuild runs and Floorplan Editor is launched. One of the following will occur: 

+ Project Navigator crashes 

+ After clicking yes to "reload or exit" dialog, Constraints Editor and Floorplan Editor close, but only Floorplan Editor is relaunched 

+ ERROR:ConstraintSystem:151 - Unable to alter the constraint manager because the shared constraint database has been closed. 

+ The constraints in the Constraints Editor tables are cleared

Solution

To work around this, manually change the UCF for timing and physical constraints. 

 

This issue will be resolved in a future release of the software.
