Design a multiple-output combinational network that has two input signals Xo and X1, two control signals Co and C1, and two output functions fo and f1.
The control signals have the following effect on the outputs. For example, when Co = 0 and C1 = 1, then fo (Xo, X1, Co, C1) = Xo and f1 (Xo, X1, Co, C1) = 0.
Write a Verilog and/or VHDL model of the circuit. Also, realize the circuit using NOR gates.
