ID:17980 "<Region target>" is constrained to the <placement/routing> region <Region bounding box(es)> that does not overlap with the region of its parent instance "<Parent region target>" <Parent region bounding box(es)>

CAUSE: In your design, the specified regions both constrain the logic, effectively constraining the logic to the intersection of the two regions. Because the regions do not overlap, the logic cannot be placed and meet both region constraints.

ACTION: In the Logic Lock Regions Window, expand or move the bounds of the region or its parent region so that the regions overlap. Preferably, the parent region should fully contain the region.
