Low-Power VLSI Design Technologies and Their Tool Chain Optimization

Abstract

Power consumption has emerged as one of the most critical design constraints in modern VLSI systems due to the proliferation of portable devices, Internet of-Things (IoT), and high-performance computing applications. This paper presents an extensive overview of low-power design methodologies and the role of optimization tools in achieving energy efficiency. It explores techniques such as clock gating, dynamic voltage scaling, multi-threshold CMOS, and power gating, along with the supporting simulation and analysis tools that enable accurate estimation of power at different stages of design. The integration of hardware-software co-design frameworks and AI-driven power prediction models is discussed to showcase the future potential of hybrid optimization. Moreover, the paper elaborates on the challenges of balancing low power with high performance, manufacturability, and reliability. By examining case studies of recent low-power VLSI implementations, this paper demonstrates how effective design tools contribute to sustainable and scalable chip design practices.
