3-bit Multiplier Verilog Code -

// Full adder chain // Stage 1: pp0[1] + pp1[0] half_adder ha1 ( .a(pp0[1]), .b(pp1[0]), .sum(product[1]), .carry(c1) );

for most FPGA/ASIC designs unless you need explicit gate-level control for teaching or low-level optimization. 3-bit multiplier verilog code

// Helper modules module half_adder ( input a, b, output sum, carry ); assign sum = a ^ b; assign carry = a & b; endmodule // Full adder chain // Stage 1: pp0[1]

// Instantiate behavioral multiplier (change as needed) multiplier_3bit_behavioral uut ( .a(a), .b(b), .product(product) ); assign sum = a ^ b

// Final stage assign product[5] = c5 | c6; // final carry out assign product[4] = (c5 ^ c6); // optional, adjust based on actual addition endmodule

// Stage 4 full_adder fa4 ( .a(c4), .b(pp2[2]), .cin(s3), .sum(product[3]), .cout(c6) );

full_adder fa3 ( .a(s2), .b(pp2[1]), .cin(c3), .sum(s3), .cout(c5) );
