If you are looking for more complex designs often found on GitHub, consider these alternatives: Wallace Tree Multiplier
module top_multiplier #( parameter ARCH_TYPE = "ARRAY" // "ARRAY", "CARRY_SAVE", "WALLACE" )( input wire clk, input wire rst_n, input wire [7:0] A, input wire [7:0] B, input wire start, output reg [15:0] P, output reg done ); wire [15:0] product;
The design of an 8-bit multiplier in Verilog represents a fundamental milestone in digital logic design, bridging the gap between basic arithmetic and high-performance computing. At its core, an 8-bit multiplier takes two 8-bit binary inputs (multiplicand and multiplier) and produces a 16-bit product . While the simplest approach is a single-line behavioral operator ( * ), professional hardware design often requires structural implementations—such as Booth’s algorithm , Wallace tree , or Array multipliers —to optimize for speed, power, or area. Core Multiplier Architectures 8bit multiplier verilog code github
A fantastic GitHub repository to explore this architecture is Design-of-various-multiplier-Array-Booth-Wallace- by pareddy113 . This project implements an array multiplier and provides Verilog code for both the multiplier and its testbench. The repository goes further by also providing a performance comparison against Booth and Wallace tree multipliers, reporting that their hybrid design achieved for 8-bit inputs.
In this article, we will explore:

This is a heavyweight among academic multiplier projects. It implements an 8-bit signed Wallace Tree Multiplier down to the CMOS transistor level. The repository includes Verilog RTL, complete schematics, and full custom chip layouts designed in Cadence Virtuoso using the NCSU 600nm (ami06) open-source process.
