MULT_AND is an AND component used exclusively for building fast and smaller multipliers. The I1 and I0 inputs must be connected to the I1 and I0 inputs of the associated LUT. The LO output must be connected to the DI input of the associated MUXCY, MUXCY_D, or MUXCY_L. See the “Example Multiplier Using MULT_AND” figure.
