Design Compiler (DC) translates high-level RTL (Verilog or VHDL) into an optimized gate-level netlist. It doesn't just "map" gates; it performs concurrent optimization for: Meeting setup and hold requirements. Minimizing the silicon footprint. Reducing both leakage and dynamic consumption. Integrating DFT (Design for Test) structures. The Core Synthesis Workflow Develop Your Library: Ensure you have your files (Target, Link, and Symbol libraries) ready. Read the Design: read_verilog commands to bring your HDL into the DC environment. Define Constraints: synopsys design compiler tutorial 2021

To run your automated synthesis script in non-interactive batch mode, open your Linux terminal and execute: dc_shell -topo -f run_synth.tcl | tee logs/synthesis.log Use code with caution.
The analyze command checks the RTL for syntax errors and builds intermediate files in the WORK directory. The elaborate command builds the generic GTECH architecture and allows parameter overriding. Read the Design: read_verilog commands to bring your
