ID:176083 Non-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 non-DPA-mode SERDES groups that overlap. Overlapping non-DPA-mode SERDES groups result in crossed non-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 non-DPA-mode SERDES groups do not have overlapping location assignments. You may also need to increase the spacing between non-DPA-mode SERDES groups.
