Consider two 4-bit binary numbers A and B. Bits of A are a3, a2, a1, and a0, and bits of B are b3, b2, b1, and b0. A is greater than B if a3 is 1 and b3 is 0, but if a3 and b3 are the same, then if a2 is 1 and b2 is 0, we can determine that A is greater than B. This evaluation continues until a0 and b0 are considered. If a0 and b0 are equal then A and B are equal. Using discrete gates and Verilog gate primitives build a 4-bit comparator that generates a 1 on its GT output when its 4-bit input A is greater than its B input, and a 1 on its EQ output when A and B are equal. Must use the generate statement and other Verilog iterative logic support structures.

Here is a Verilog code for a 4-bit comparator that generates a 1 on its GT output when its 4-bit input A is greater than its B input, and a 1 on its EQ output when A and B are equal:

module comparator(A, B, GT, EQ);
  input [3:0] A, B;
  output GT, EQ;
  
  wire [3:0] diff;
  assign diff = A - B;
  
  assign GT = diff[3] & ~B[3] | diff[2] & ~B[2] & ~diff[3] | diff[1] & ~B[1] & ~diff[3] & ~diff[2] | diff[0] & ~B[0] & ~diff[3] & ~diff[2] & ~diff[1];
  assign EQ = ~(diff[3] | diff[2] | diff[1] | diff[0]);
  
endmodule

In this code, we first subtract B from A to get the difference between the two numbers. Then we use the rules given in the problem statement to determine whether A is greater than B or equal to B. The generate statement and iterative logic support structures are not needed for this specific problem.
