Enhancing Block Level Performance with CTS Optimization for High-Frequency Nodes in SOC

Abstract

In the realm of Very-Large-Scale Integration (VLSI) circuit design, achieving optimal performance in System-on-Chip (SoC) architectures for high-frequency nodes presents significant challenges. As semiconductor technology advances, the demand for higher performance, lower power consumption, and increased reliability intensifies. Clock Tree Synthesis (CTS) optimization emerges as a pivotal technique to address these demands. This paper explores the enhancement of VLSI circuit performance through CTS optimization specifically tailored for high-frequency nodes within SoC designs. CTS optimization aims to minimize clock skew, reduce jitter, and ensure precise timing closure, which are critical for maintaining the synchronization of high-speed operations. The integration of advanced CTS techniques, such as Multi-Point Clock Tree Synthesis (MPCTS), plays a crucial role in achieving these objectives. MPCTS leverages multiple clock insertion points, providing a more balanced and efficient clock distribution network that significantly reduces WNS, latency and area
