In the dc_shell prompt:

Builds the design hierarchy and identifies generic logic. elaborate top_module Use code with caution. 3. Applying Design Constraints

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)

Design Compiler is a . Without specifications regarding speed, area, and power, the tool cannot optimize the logic effectively. Constraints are typically defined using Synopsys Design Constraints (SDC) syntax. Clock Definition

Save your optimized gate-level assets to hand off to the Physical Design (Place and Route) team. After compile_ultra , run a quick incremental pass

In 2021 flows, you typically have two options:

Before diving into the synthesis commands, you must create a stable and correctly configured working environment. This involves setting up tool-specific configuration files and environment variables.

If a combinational path between two registers is too long, use register retiming to move registers across combinational logic gates. This rebalances path delays without altering the design's functionality. or unconnected ports.
