In this tutorial, we provided a comprehensive overview of Synopsys Design Compiler, covering its features, setup, and usage. We hope this tutorial has provided a solid foundation for designing and optimizing digital circuits using Synopsys Design Compiler. With practice and experience, you can master the tool and create efficient digital designs.

Started using the dc_shell command. An interactive command-line interface based on Tcl. Ideal for executing commands step-by-step and testing script segments.

Before running Design Compiler, you must configure the tool environment variables. This is done by creating a setup file named .synopsys_dc.setup in your project working directory. Key Library Variables
