1.15.4. FAST_OCT_REGISTER

Implements an OCT register in a cell that has a fast, direct connection to an I/O pin. Turning on the Fast OCT Register option can help maximize I/O timing performance, for example, by permitting fast clock-to-output times. Turning this option off for a particular signal prevents the Fitter from implementing the signal automatically in an I/O cell. This option is ignored if it is applied to anything other than a register or an output or bidirectional pin fed by a register.
