5.1i PACE - An area constraint contains discrete logic that is selected when the area constraint is selected

Description

Keywords: discrete, logic, area, constraint, selected

Urgency: Standard

General Description:
I place discrete logic (DCMs, BUFGs, etc), then create an area constraint with the remaining logic. If I select the area constraint, the discrete logic is also selected, and I cannot move the area constraint to a new location. How do I move my area constraints?

Solution

To work-around this issue, use Ctrl+Select to de-select the BUFGs, DCMs, etc. The area constraint may now be moved.

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 1.
