ID:176078 Can't merge fast PLL <name> and fast PLL <name>: fast PLLs contain a total of <number> unique counters, but only <number> counters are available on single fast PLL

CAUSE: The Fitter tried to merge the specified fast PLLs that contain the specified number of unique counters. However, the Fitter cannot merge the fast PLLs because only the specified number of counters are available in a single fast PLL.

ACTION: Modify the design so that the fast PLLs contain the same number of counters.
