8.1i Constraints Editor - Constraints Editor incorrectly allows the creation of IOBDELAY constraints for outputs that are in a 3-state condition

Description

The Constraints Editor is allowing me to create IOBDELAY constraints for outputs that are in a 3-state condition. Is this correct?

Solution

The IOBDELAY should be "N/A" for outputs that are in a 3-state condition (the same as any normal output).

This is scheduled to be fixed in the next major release of the design tools .
