xnr2 standard cell family

 2-I/P exclusive NOR gate
xnr2 symbol
4 XNOR gates designed for minimum transistor count and hence smallest size. The Prop and Ramp delays below are the average of the inverting and non-inverting delays. The Synopsys Liberty format .LIB file has the correct delays for each case.
