A standard synthesis flow in DC, as outlined in Synopsys training materials, follows a sequence of steps:
This is the most critical report. It shows the longest path (Critical Path) in the design.
# Check design for issues (e.g., unresolved references, floating ports) check_design
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. synopsys design compiler tutorial 2021

Comprehensive Synopsys Design Compiler Tutorial Synopsys Design Compiler (DC) is the industry-standard tool for RTL synthesis. It translates your Hardware Description Language (HDL) code, such as Verilog or VHDL, into a technology-specific gate-level netlist. This tutorial guides you through the complete synthesis flow using the modern Design Compiler Topographical mode. 1. Introduction to Synthesis Flow A standard synthesis flow in DC, as outlined
This step models the external conditions your chip will operate in. You define the operating conditions (PVT: Process, Voltage, Temperature), wire load models (to estimate wiring delay), and I/O characteristics (e.g., the drive strength of external cells using set_driving_cell or the load on outputs using set_load ).
For the digital designer, mastering DC 2021 means mastering the transition from abstract behavior to concrete silicon—one Tcl command at a time.
