ID:176084 Non-DPA-mode and DPA-mode SERDES groups overlap and are driven by different PLLs -- 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 other fast PLL. Overlapping non-DPA-mode and 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 the non-DPA-mode and DPA-mode SERDES groups is required.

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