Precise clock uncertainty modeling: Optimizing high-frequency clock design for maximum PPA
Year: 2025
Type: article
Abstract: This article explores the critical role of clock uncertainty modeling in modern integrated circuit design, focusing on its impact on Power, Performance, and Area (PPA) optimization. The article examines various aspects of clock uncertainty, including cycle-to-cycle jitter, duty cycle distortion, and process variations in advanced technology nodes. The article investigates both optimistic and pessimistic modeling approaches, analyzing their effects on design success and system reliability. Through comprehensive analysis of timing requirements, thermal considerations, and environmental factors, the article presents strategies for achieving precise clock uncertainty modeling while maintaining design efficiency. The article emphasizes the importance of balanced uncertainty management in high-frequency designs and provides insights into best practices for clock distribution network optimization.
