Digital logic design forms the backbone of modern computing, and among the most fundamental arithmetic operations is multiplication. While software languages abstract this away with a simple * operator, hardware engineers often need to understand the underlying gate-level mechanics, especially when optimizing for speed, area, or creating custom processing units. // Column 2 (Weight 4) wire p0_2 =
module multiplier_3bit ( input [2:0] A, input [2:0] B, output [5:0] Product ); // --- Internal Wires --- We generate partial products using AND gates and
module full_adder ( input a, input b, input cin, output sum, output cout ); assign sum = a ^ b ^ cin; assign cout = (a & b) | (b & cin) | (a & cin); endmodule Here is the complete code for a 3-bit multiplier using the structural approach. We generate partial products using AND gates and use instances of the full adder to sum them.
