System-on-a-Chip (SoC) Solutions for IoT-Based Industrial Networks: Current Applications and Future Pathways

The rapid advancement of semiconductor technology has significantly influenced the development and testing of System-on-a-Chip (SoC) solutions, particularly in the domain of Internet of Things (IoT) automation. This paper reviews the current state of key SoC testing technologies globally, addressing the challenges of integration and the strategies employed to reduce test costs and improve chip reliability. Key technical approaches are examined in three areas: system-level verification, high-speed signal testing, and test optimization. The paper also explores the evolving landscape of SoC design, highlighting unresolved issues of testability and design that affect IoT advancements. As devices and machines become increasingly efficient and compact, SoC platforms must meet specific IoT application requirements. The integration of multiple cores on a single SoC platform shows promise for IoT applications, though it poses challenges in inter-core communication efficiency. Heterogeneous Network-on-Chip Simulators address these challenges by enhancing the interconnectivity within multiprocessor systems. This paper highlights critical aspects of IoT systems, such as power consumption, throughput, and latency, and provides insights into the deployment of SoC solutions in IoT, sensor advancements, and methodological innovations. Future directions in SoC testing and design are discussed, aiming to further the capabilities and applications of SoC in IoT automation. The development and testing of SoC technology represent a paradigm shift from traditional computing systems to more efficient and connected IoT devices. By addressing advanced testing technologies and integration challenges, IoT applications are poised for significant innovation, paving the way toward a smarter, more connected future.
