8.1i PAR - In a design, components are placed outside their area groups


When I specify an area group using slice locations, components included in a given area group are placed immediately outside of the area group.


This problem is because of a discrepancy that occurs in the slice-ordering within a CLB, between the grid system used to specify the area group range and the grid system that is actually used by the placer. 


If the area group range constraint is specified along CLB boundaries, this discrepancy between grid systems will not occur.
