ID:186039 Clock input port of fast PLL "<name>" must be driven by an I/O pin

CAUSE: The clock input port of the specified receiver fast PLL is not driven by an I/O pin. However, for better receiver input skew margin (RSKM) performance a receiver fast PLL requires a dedicated connection between an I/O pin and the clock input port.

ACTION: Modify the design so that an I/O pin drives the receiver fast PLL.
