Abstract —This paper presents the design, implementation, and simulation of an 8-bit array multiplier using Verilog HDL. Array multipliers offer a regular structure suitable for VLSI implementation. The design utilizes full adders and half adders arranged in a systolic array to compute the product of two 8-bit unsigned numbers, resulting in a 16-bit output. The code is synthesized for generic digital design and validated through simulation testbenches. 1. Introduction Multiplication is a fundamental arithmetic operation in digital signal processing (DSP), microprocessors, and AI accelerators. While sequential multipliers save area, parallel array multipliers achieve high speed by computing partial products simultaneously. The array multiplier is particularly attractive due to its regular layout, making it easy to fabricate and pipeline. // Row 7: full adders for all but
