What Is Clock Tree Synthesis in the Implementation Flow?

Clock Tree Synthesis (CTS) is a critical step in the chip implementation flow, ensuring the clock signal reaches every flip-flop and latch at the right time. This video explains what CTS is, why it matters, and how techniques like buffer insertion, skew balancing, and useful skew optimize timing and power. What is CTS? CTS inserts buffers into the clock path to minimize clock skew and latency, transforming an ideal clock network into a practical one. Goal : Deliver the clock signal to all sequential elements with minimal skew, balanced delays, and optimized timing. Key Concepts : Clock Skew: Difference in arrival times of the clock signal at different sinks (flip-flops/latches). Latency: Delay from the clock source to the sinks. Global Skew Balancing: Equalizes delays within tolerance across sinks. Useful Skew: Intentional skew adjustments to improve timing slack and reduce clock area. Why CTS matters? • Synchronizes data communication across registers. • Reduces timing violations by balancing delays. • Enables timing closure for complex SOC designs. • Supports power optimization by leveraging skew intelligently. Key Topics Covered : • Definition of Clock Tree Synthesis in chip implementation • Why CTS is essential for timing closure • Buffers and routing adjustments for skew and latency • Global skew balancing vs useful skew • Impact on flip-flops, latches, and overall chip performance • How CTS helps optimize timing slack and save power Timestamps : (00:00) – What is Clock Tree Synthesis?
