STRATIX_DECREASE_INPUT_DELAY_TO_INTERNAL_CELLS<br />

Type<br />

Decreases the propagation delay from an input or bidirectional pin to logic and<br />

embedded cells within the device. This is an advanced option that should be used<br />

only after you have compiled a project, checked the I/O timing, and determined that<br />

the timing is unsatisfactory. For detailed information on how to use this option, refer<br />

to the data sheet for the device family. This option is ignored if it is applied to<br />

anything other than an input or bidirectional pin.<br />
