ID:186053 All differential I/O SERDES receivers that are driven by fast PLL "<name>" must have same CORE_CLK input port source

CAUSE: All differential I/O SERDES receivers that are driven by the specified fast PLL do not have the same CORE_CLK input port source. All differential I/O SERDES receivers that are driven by a fast PLL must have the same CORE_CLK input port source.

ACTION: Modify the design so that all differential I/O SERDES receivers that are driven by the fast PLL have the same CORE_CLK input port source.
