3.1i Virtex-II PAR - Placer fails to meet valid area group constraints.


Keywords: area, group, placer, constraints, ERROR:Place:79

Urgency: Standard

General Description:
The placer fails to meet valid area group constraints, which results in the following error:

ERROR:Place:79 - There were not enough sites to place all selected components. This is probably due either to lack of resources, preference conflicts, or macro configuration placement requirements which can not be met. If PAR has been run, please check the .par file for resource allocation and utilization and verify that there are sufficient resources to place the component(s). Also ensure that all placement conflicts have been resolved. If neither of these seem to be a problem examine the size and shape of the macros in the design to make sure they all may placed on the device at the same time.


This problem is fixed in the latest 3.1i Service Pack, available at:
The first service pack containing the fix is 3.1i Service Pack 8.
