Here is why you should re-read (or read) this guide, and the three key takeaways that will improve your PPA (Power, Performance, Area). synopsys timing constraints and optimization user guide 2021

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: Incremental delay: How much time each gate/wire adds. Path type: Whether it's a setup (max) or hold (min) check. Feature Article: Mastering the Clock: A Deep Dive

Once basics are defined, the tool optimizes specific paths to meet targets: Here is why you should re-read (or read)
