Maximizing efficiency: building and running an AMBA APB protocol with open-source solutions

Advanced Peripheral Bus (APB) protocol is a key component belonging to Advanced Microcontroller Bus Architecture (AMBA) family. The APB protocol is a form of communication between the test bench and design under test (DUT) where it allows for implementation of tests. This protocol is convivial for low-cost, low-bandwidth, and lowpower devices, like timers and keypads, to the bus system. This protocol is implemented using a reusable System on Chip (SoC) technique to address the challenges posed by Very Large-Scale Integration (VLSI). Designing and implementing the APB protocol involves creating test cases and programming the design using Verilog Hardware Description Language (HDL), while verifying the design using Verilog Test Bench. Open-source software, such as EDA Playground. The objective of the proposed work is to design and execute the AMBA APB protocol using opensource software, with a focus on ensuring the design's correctness and efficiency. It also develops a robust, efficient, and cost-effective system that can be easily integrated into various hardware designs. This work explores six distinct test cases, encompassing a range of transaction scenarios. The successful implementation of APB protocol will provide a significant contribution to the field of computer engineering, particularly in the area of hardware design and communication protocols.
