Synopsys Timing Constraints and Optimization User Guide

The is a primary resource for designers using tools like Design Compiler and PrimeTime to manage design intent and performance. The 2021 edition focuses on using Synopsys Design Constraints (SDC) to drive Power, Performance, and Area (PPA) improvements through accurate timing analysis. 1. Core Constraint Definitions

High-Definition (HD) optimization

A standout feature detailed in this year’s guide is . The documentation outlines how the tool now dynamically swaps between different implementations of a logic block (e.g., switching from a complex AOI gate to a simpler NAND/NOR structure) based on the slack available. synopsys timing constraints and optimization user guide 2021

  • Account for board-level uncertainties and IO timing (driver/receiver delays).
  • For multi-cycle or launched capture schemes from external interfaces, combine input_delay/output_delay with set_multicycle_path or set_false_path as appropriate.

    • Here is a step-by-step solution to the example use case: Synopsys Timing Constraints and Optimization User Guide The
