PrimeTime is the industry standard for sign-off. The 2021 guidelines emphasize using PrimeTime (or PrimeTime SI) for final verification.
: Use Synopsys Timing Constraints Manager to catch SDC errors before starting long synthesis runs.
Synopsys provides a range of tools for timing optimization, including:
Input and output delays describe the timing budget consumed outside your design module.
Allowing multiple clock cycles for a path.
To get the most out of Synopsys' timing constraints and optimization capabilities, designers should follow best practices:

By following the guide, engineering teams ensure their chips work correctly on the very first try. This saves companies millions of dollars in testing. To help you find the exact details you need, tell me:
For the most up-to-date and specific version of this manual (e.g., the release), you can access the full PDF through the Synopsys SolvNetPlus portal, which requires a registered customer account. UG0679: Timing Constraints Editor User Guide - AWS
Clearly define set_clock_groups for asynchronous domains to prevent unnecessary timing analysis on paths that are logically separated.
This comprehensive guide breaks down the core concepts, methodologies, and practical strategies outlined in the . Whether you are targeting Design Compiler (DC) for synthesis or IC Compiler II (ICC2) for place-and-route, this article provides the foundational knowledge and advanced techniques needed to achieve timing closure efficiently. 1. Fundamentals of Synopsys Timing Constraints
Here are some common commands used to define timing constraints:
