10.1 PACE Virtex-4 - Area Group for DSPs cannot be added by PACE

Description

My design includes DSPs. When I place an area constraint or group in PACE, the UCF does not constrain the RANGE constraints for DSPs, so I am not able to write AREA Group for DSPs in PACE.

Why does PACE not generate area constraints for SLICE?

Solution

To work around this issue, manually modify the UCF and add the RANGE constraints for the DSPs.

You can also work around the issue by placing an area constraint or group including DSPs in Floorplanner.
