Two-bit equality (Mt2015 eq2)

Problem Statement

Taken from 2015 midterm question 1k

Create a circuit that has two 2-bit inputs A[1:0] and B[1:0], and produces an output z. The value of z should be 1 if A = B, otherwise z should be 0.

module top_module ( input [1:0] A, input [1:0] B, output z ); 
    assign z = (A == B) ?  1'b1 : 1'b0 ;
endmodule
