: Designers define design rules and goals, such as clock speed, input/output delays, and area limits, using Synopsys Design Constraints (SDC). Optimization & Compilation synopsys design compiler tutorial 2021

During the link step, Design Compiler resolves references between your modules and connects them to the libraries listed in your link_library variable. The check_design command identifies potential synthesis hazards such as latches, multi-driven nets, or unconnected ports. 4. Defining Design Constraints (SDC) The most critical constraint, defining the period and

Includes the target library plus any pre-compiled macros or memory.

Constraints dictate how hard the optimization engine needs to work. Without design constraints, Design Compiler will map logic with minimal regard for timing or power footprint.
