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