I have used LOC constraints on some logic that also belongs to an AREA GROUP. How does this affect AREA GROUP membership?
The LOC constraint affects AREA GROUP membership depending on whether the LOC constraint targets a site that is inside or outside the AREA GROUP RANGE. The components involved will maintain AREA GROUP membership only if they will be placed inside the AREA GROUP RANGE. This is done so that the AREA GROUP can be sized properly with respect to the RANGE.
