Description
Keywords: Floorplanner, overlap, area group, warning, instance, more, two, range
Urgency: Standard
General Description:
When my design contains non-rectangular area groups made by PACE, area groups containing block RAMs/multipliers, or overlapping constraints, Floorplanner reports the following warning numerous times:
"Warning: Instance "x" has more than two area range constraints."
Solution
Floorplanner will generate these warning messages when it loads a design with non-rectangular area groups. Using Floorplanner to modify a non- rectangular area group will result in corruption of the UCF. If possible, use PACE to modify area group constraints.Updates in 5.1i Service Pack 3 will enable the numerous warning messages to be logged.
This problem is fixed in the latest 5.1i Service Pack, available at:

The first service pack containing the fix is 5.1i Service Pack 3.
