APEX20K_DECREASE_INPUT_DELAY_TO_INTERNAL_CELLS
Decreases the propagation delay from an input or bidirectional pin to logic and embedded cells within the
device. 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.
