ID:12618 <number> input pin(s) will use non-dedicated clock routing -- review the clock promotion messages above for details

CAUSE: One or more global signals driven by I/Os cannot be routed using dedicated clock routing. In the clock promotion summary messages above, separate warnings have been generated for each affected signal. To improve jitter performance and reduce clock skew, Intel recommends using dedicated REFCLK I/Os to drive global clocks.

ACTION: For possible solutions, review the detailed help in the warning message for each affected signal.
