User Guide 2021: Synopsys Timing Constraints And Optimization

: Use report_timing with detailed options to identify if a violation is caused by logic depth, high fan-out, or poor placement.

The 2021 guide emphasizes PrimeTime as the industry "golden" signoff tool. synopsys timing constraints and optimization user guide 2021

: The primary constraint is create_clock , which defines the period and duty cycle. Secondary clocks, such as generated clocks for frequency dividers, are defined using create_generated_clock . : Use report_timing with detailed options to identify

The user guide outlines several stages of optimization to meet Performance, Power, and Area (PPA) goals. Secondary clocks, such as generated clocks for frequency

: The guide explains how to interpret "slack"—the difference between the required arrival time and the actual arrival time. A negative slack indicates a timing violation that must be addressed through optimization.

: When the standard single-cycle timing model is too restrictive, exceptions are used:
