ID:176075 Can't merge fast PLL <name> and fast PLL <name> -- fast PLLs contain <number> unique DPA counters, but only one DPA counter is available on single fast PLL

CAUSE: The Fitter tried to merge the specified fast PLLs that contain the specified number of unique DPA counters. However, the Fitter cannot merge the fast PLLs because only one DPA counter is available on a single fast PLL. DPA counters are defined as PLL taps that can drive a SERDES in DPA-mode via an SCLK connection.

ACTION: Modify the design so that the fast PLLs contain the same number of DPA counters, or change the corresponding SERDES to be in non-DPA mode.
