9.2 PACE - "ERROR:DesignEntry - Could not apply constraint..."

Description

Keywords: PACE, Error, DesignEntry, Constraint

When selecting the UCF file under Processes/UserConstraints and then double-clicking on AssignPackagePins, I receive the error message:

"9.2i - PACE - ERROR:DesignEntry - Could not apply constraint..."

How do I resolve this issue?

Solution

One work-around to this issue is to open PACE and assign package pins by opening PACE under the Translate options. The option is under Implement Design ==> Translate ==> Assign Package Pins Post-Translate.

A second option is to try launching PACE in standalone by running Start ==> Xilinx ==> Accessories ==> PACE. Then select the UCF file and project NGD file.

A third option would be to manually enter the constraints.
