The data arrived before it was required. Your design meets timing.
With the design, environment, and constraints set, you run the compile or compile_ultra command. This command orchestrates the translation, optimization, and mapping steps. For large designs, a two-phase compile strategy ( compile -map_effort high -scan -timing_high_effort ) is often used to achieve the best Quality-of-Results (QoR).
The time it takes for data to propagate from the launch flip-flop through the combinational cloud to the destination point. synopsys design compiler tutorial 2021
Are there any in your design like RAMs, PLLs, or clock-gating cells?

A tutorial on for 2021 focuses on the industry-standard logic synthesis flow, transforming high-level Register Transfer Level (RTL) code into an optimized gate-level netlist. Using modern features like Topographical technology , designers can achieve timing and area results within 10% of post-layout physical implementation. 1. Environment Setup

Before starting DC, you must set up the environment correctly. The configuration is largely controlled by a file named .synopsys_dc.setup in your working directory. This hidden file tells DC where to find all the necessary design data and libraries. The key libraries you need to define are:
DC applies Boolean structuring and mapping algorithms to optimize the design logic based on your user constraints.
