14.4 PlanAhead - Changes are not saved in the UCF file when multiple instances are "Fixed" at once


If the PlanAhead tool is launched from within Project Navigator (e.g., Analyze Timing / Floorplan Design (PlanAhead)), some constraints are not saved when prompted.

For example, when multiple block RAM instances are selected in the Device View, and Fix Instances is selected, these constraints are not saved in the UCF when the constraints are saved (File -> Save Constraints).

However, when one block RAM instance is selected, this constraint is saved in the UCF when the constraints are then saved (File -> Save Constraints).


This issue has been resolved in the 14.5 PlanAhead tool.
