PAD_TO_INPUT_REGISTER_DELAY
Specifies the propagation delay from an input pin to the data input of the input register implemented 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 is ignored
if it is applied to anything other than an input or bidirectional pin.
