Altera Quartus II Settings File - Manual (Page 496)

DECREASE_INPUT_DELAY_TO_OUTPUT_REGISTER
Decreases the propagation delay from the interior of the device to the data input of the output register
implemented in an I/O cell. This is an advanced option that should be used only after you have compiled
a project, checked the I/O timing, and determined that the timing is unsatisfactory. For detailed
information on how to use this option, refer to the data sheet for the device family. This option is ignored
if it is applied to anything other an output or bidirectional pin that is associated with an output register
implemented in an I/O cell.
