ID:176431 Too many Input Delay from Pin to Internal Cells logic option assignments to input pin <name> and its fan-outs -- honoring only <number> assignment(s) (ignored setting = <number>)

CAUSE: You made more than two Input Delay from Pin to Internal Cells logic option assignments to the specified input pin and its fan-outs. However, the target device can support only two of these assignments. The Fitter is arbitrarily honoring two assignments and ignoring the rest.

ACTION: Delete some assignments so that there are no more than two Input Delay from Pin to Internal Cells logic option assignments to the specified input pin and its fan-outs.
