ID:176082 DPA-mode SERDES groups overlap -- in rows (<number>-<number>) <name> side, fast PLL <name> group1 Y-range=(<number>-<number>) overlaps with fast PLL <name> group2 Y-range=(<number>-<number>)

CAUSE: The Fitter tried to place the specified fast PLLs in the specified locations. However, the fast PLLs drive DPA-mode SERDES groups that overlap. Overlapping DPA-mode SERDES groups result in crossed DPA clock domains. As a result, the Fitter could not place the specified fast PLLs. This message can occur when there are overlapping location assignments or if additional spacing between DPA-mode SERDES groups is also required.

ACTION: Modify the design so that the DPA-mode SERDES groups do not have overlapping location assignments. You may also need to increase the spacing between DPA-mode SERDES groups.
