ID:176085 Non-DPA-mode and DPA-mode SERDES groups driven by the same fast PLL overlap -- in rows (<number>-<number>) <name> side, fast PLL <name> DPA-mode group1 Y-range=(<number>-<number>) overlaps with fast PLL <name> non-DPA-mode group2 Y-range=(<number>-<number>)

CAUSE: The Fitter tried to place the specified fast PLLs in the specified locations. However, one fast PLL drives a non-DPA-mode SERDES group that overlaps with a DPA-mode SERDES group driven by the same fast PLL. Non-DPA-mode SERDES groups and DPA-mode SERDES groups cannot overlap due to DPA clock constraints. As a result, the Fitter could not place the specified fast PLLs. This message can occur when there are overlapping location assignments.

ACTION: Modify the design so that the non-DPA-mode SERDES group and DPA-mode SERDES group driven by the same fast PLL do not overlap.
