OXNOR2 is a 2-input exclusive NOR gate that is implemented in the output multiplexer of the XC4000X and SpartanXL IOB. The F pin is faster than I0. Input pins can be inverted even though there is no library component showing inverted inputs. The mapper will automatically bring any inverted input pins into the IOB.
