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. synopsys design compiler tutorial 2021
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.
This 2021 tutorial focuses on the modern and the core commands needed to navigate the synthesis flow effectively. 1. Understanding the Synthesis Flow set_max_area 0 ;# Tells DC to make the
Once the synthesis is finished, you must verify if your constraints were met. report_timing (Check for Setup/Hold violations). Area: report_area (Check gate count and physical size). Constraint Violations: report_constraint -all_violators . 7. Exporting the Netlist
Always run link after elaboration to ensure all modules are found. You can use read_verilog or the modern analyze
Be careful using set_dont_touch on modules, as it prevents DC from optimizing across boundaries.
Before launching DC, you must define your library paths. This is typically done in a .synopsys_dc.setup file in your home directory or project folder.
Finalizing the gate-level netlist based on constraints. 2. Setting Up Your Environment
