10.1 Floorplan Editor Virtex-4/-5 - Unable to apply I/O-specific constraints (DRIVE, IOBDELAY, IOSTANDARD)

Description

When I create I/O constraints (IOSTANDARD, IOBELAY, and DRIVE) through the Design Objects tab, after launching Assign Area Constraints, I receive an error message that constraints could not be applied to this net.

Solution

To work around this issue, create the constraints manually in a text editor or use PlanAhead.
