DECREASE_INPUT_DELAY_TO_INPUT_REGISTER<br />

DECREASE_INPUT_DELAY_TO_INPUT_REGISTER<br />

Type<br />

Decreases the propagation delay from an input pin to the data input of the input<br />

register implemented in the I/O cell associated with the pin. This is an advanced<br />

option that should be used only after you have compiled a project, checked the I/O<br />

timing, and determined that the timing is unsatisfactory. For detailed information on<br />

how to use this option, refer to the data sheet for the device family. This option is<br />

ignored if it is applied to anything other than an input or bidirectional pin.<br />
