3-bit Multiplier Verilog Code |verified|

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

// State Flip-Flops always @(posedge clk or negedge rst_n) begin if (!rst_n) state <= IDLE; else state <= next_state; end

For N>8, always prefer sequential or use built-in DSP slices. 3-bit multiplier verilog code

// Stage 2 full_adder fa1 ( .a(pp0[2]), .b(pp1[1]), .cin(c1), .sum(s1), .cout(c2) );

// Partial Products (mapped to specific wire columns) // Column 0 (Weight 1) wire p0_0 = A[0] & B[0]; // Product bit 0 module full_adder ( input a, input b, input

// Row 1: Add pp0[1] and pp1[0] half_adder ha0 (.a(pp0[1]), .b(pp1[0]), .sum(p_temp[1]), .cout(ha0_c));

// Row 5: Add pp2[2] and fa2_c half_adder ha1 (.a(pp2[2]), .b(fa2_c), .sum(p_temp[5]), .cout()); module full_adder ( input a

// Row 3: Add pp1[2], pp2[0], and fa0_c full_adder fa1 (.a(pp1[2]), .b(pp2[0]), .cin(fa0_c), .sum(p_temp[3]), .cout(fa1_c));

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

For a 3x3 array multiplier, the typical hardware requirement is 9 AND gates, 3 half adders, and 3 full adders Verilog Implementation
