In the world of VLSI, remains the industry standard for logic synthesis. Whether you are a student or a professional engineer, mastering DC is essential for transforming high-level RTL (Verilog/VHDL) into an optimized gate-level netlist.
However, a tutorial is only the first step. The real skill lies in reading the *.rpt files and deciphering why the compiler made specific choices. Your next steps should be:
What specific (e.g., 65nm, 28nm, FinFET) are you targeting? Share public link
set_app_var mw_reference_library "/path/to/frames" set_app_var mw_design_library "my_mw_lib" create_mw_lib -technology /path/to/techfile.tf $mw_design_library set_mw_lib_reference -mw_lib_design $mw_design_library -mw_lib_reference $mw_reference_library Use code with caution. Step 4: Compile/Optimize synopsys design compiler tutorial 2021
Synopsys Design Compiler has a rich history, with several editions serving different design needs. As of 2021, the most relevant versions for a standard user were:
Before starting, ensure your Linux environment is configured to locate the Synopsys binaries and licenses.
This 2021 tutorial focuses on the modern and the core commands needed to navigate the synthesis flow effectively. 1. Understanding the Synthesis Flow In the world of VLSI, remains the industry
You can use read_verilog or the modern analyze and elaborate flow. The latter is preferred as it allows for better error checking and parameter passing.
