Synopsys Timing Constraints And Optimization User Guide 2021 ((better)) -

Input and output delays describe the timing budget consumed outside your design module.

High differences between the launch clock arrival time and capture clock arrival time can destroy your setup or hold margins. If skew is high, check the clock tree synthesis (CTS) configuration. Common Solutions for Timing Violations

The 2021 guide heavily emphasizes constraint quality . Synopsys introduced stricter linting for SDC (Synopsys Design Constraints).

What are you using (e.g., Wireload models or Graphical/Topographical mode)? synopsys timing constraints and optimization user guide 2021

The Synopsys Timing Constraints and Optimization User Guide (2021 releases) provides essential methodologies for defining design intent via SDC constraints in synthesis tools like Design Compiler. It covers timing assertions for clocks and I/O, optimization strategies for PPA goals, and verification methods to ensure design success. Official documentation for these releases is accessible through Synopsys SolvNetPlus, with archived versions available for specific software releases.

The clock is the heartbeat of your SoC. The guide details three critical steps for clock definition:

Here are some best practices for timing optimization: Input and output delays describe the timing budget

The guide concludes with a heavy focus on debug. The report_timing command is the engineer's most powerful diagnostic tool. It breaks down a path into: How much time each gate/wire adds. Path type: Whether it's a setup (max) or hold (min) check.

The is a primary reference for digital designers using tools like Design Compiler and PrimeTime to achieve timing closure . The guide covers the creation and management of Synopsys Design Constraints (SDC) , which are essential for guiding synthesis and place-and-route tools to meet performance, area, and power goals.
