ID:176096 Both fast PLL <name> SCLKOUT ports must drive SERDES

CAUSE: The Fitter tried to place the specified fast PLL. However, neither of the fast PLL SCLKOUT[0-1] ports drive a SERDES. Both SCLKOUT ports of a fast PLL must drive a SERDES. As a result, the Fitter could not place the fast PLL.

ACTION: Modify the design so that both SCLKOUT ports of the fast PLL drive a SERDES.
