5. Timing Constraints and Analysis

Timing is a critical aspect of VLSI design, necessary for ensuring circuit operation within specified constraints to prevent errors such as data corruption and timing mismatches. The chapter outlines the definition of timing constraints, implementation strategies, and methods for timing analysis, including static timing analysis and post-layout verification. Effective mitigation strategies to address timing violations are also discussed, emphasizing the importance of timing optimization for high-performance chip designs.
