Synopsys Timing Constraints And Optimization User Guide Guide

Example:

Ultimately, the guide teaches that timing closure is not magic; it is a systematic process of specifying intent (constraints) and iterating toward convergence (optimization). A designer who understands why set_multicycle_path requires a hold adjustment, or why virtual clocks prevent I/O interface failures, is a designer who will tape out successfully on the first attempt.

Everything starts with the clock. In Synopsys tools, the create_clock command defines the period, duty cycle, and source. Defined on input ports.

The guide explains the 15 options of report_timing . The most powerful is -path_type :
