Synopsys Timing Constraints And Optimization User Guide 2021 Jun 2026

: Accounting for clock source latency, ideal network latency, and clock uncertainty (skew and jitter).

: Instructions for creating primary clocks, generated clocks (for PLLs/dividers), and defining clock attributes like jitter (uncertainty) and latency. synopsys timing constraints and optimization user guide 2021

Timing constraints are the "instructions" that tell synthesis and implementation tools how fast a design must run. Without accurate constraints, optimization results are essentially meaningless. : Accounting for clock source latency, ideal network

The 2021 guide's climax is Chapter 12: "Achieving PrimeTime Correlation." : Accounting for clock source latency
