Verilog

Verilog. One-bit Full Adder. module full_adder (A,B,Cin,Sum, Cout); input A,B,Cin; output Sum, Cout; assign Sum = (A &amp; B &amp; Cin) | (~A &amp; ~B &amp; Cin) | (~A &amp; B &amp; ~Cin) | (A &amp; ~B &amp; ~Cin); assign Cout = (A &amp; Cin) | (A &amp; B) | (B &amp; Cin); endmodule. Four-bit Adder.
