Input Delay from Pin to DDIO Low Capture Input Register logic option

A logic option that specifies the propagation delay from an input pin to the data input of the DDIO low capture input register in the I/O cell associated with the pin. 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 must be assigned to an input or bidirectional pin that uses DDIO circuitry or it is ignored.

This option is available for Arria^® II GX devices.
