5.1i Constraints Editor - Outputs in a 3-state condition are not recognized


General Description:

When I open a design with I/O types, Constraints Editor does not recognize the 3-state outputs. (Additionally, this does not appear in the Ports tab.)


To work around this problem, manually modify the UCF to add the particular constraint that you wish to place on the 3-state I/O port.

This will be fixed in the next major software release (after 5.1i).
