ID:170088 <number> (of <number>) connections in the design require a large routing delay to satisfy hold requirements. Refer to the Estimated Delay Added for Hold Timing Fitter report panel for a summary of the relevant clock transfers. Also, check the timing constraints of the circuits and clocking methodology, especially multicycles and gated clocks.

CAUSE: The Fitter has detected that excessive routing delays are required for certain connections to satisfy hold requirements. This requirement might be caused by incorrect timing constraints such as multicycles or the use of gated clocks.

ACTION: Verify that the timing constraints, especially multicycles, are set properly. Avoid using gated clocking.
