ID:16146 Ignored Input Delay from Pin to Internal Cells option assignment (setting = <number>) to input or bidirectional pin <name> -- all fan-out already have assignments of a different delay value or are fed by the pin through global or regional clocks

CAUSE: You assigned the Input Delay from Pin to Internal Cells option to the specified input or bidirectional pin. You also made one or more Input Delay from Pin to Internal Cells or Global Signal option assignments to all of the fan-out for the pin. However, these assignments do not agree with one another, and as a result, the Fitter ignored the assignment.

ACTION: Delete the assignment.
