Synthesis is not just "translating" code. It is an optimization process that balances the trinity: Power, Performance, and Area. The basic workflow involves:
In 2021, most designs use or Topographical mode . This mode uses physical data (like floorplan info) to predict wire delays more accurately than the old "Wire Load Models." synopsys design compiler tutorial 2021
# Analyze the RTL (Checks for syntax) analyze -format verilog {my_design.v sub_module.v} # Elaborate (Builds the generic technology-independent design) elaborate my_design # Set the current design context current_design my_design Use code with caution. 4. Applying Constraints (The SDC File) Synthesis is not just "translating" code
This 2021 tutorial focuses on the modern and the core commands needed to navigate the synthesis flow effectively. 1. Understanding the Synthesis Flow This mode uses physical data (like floorplan info)
write -format verilog -hierarchy -output "my_design_netlist.v" write_sdc "my_design_final.sdc" Use code with caution. Pro-Tips for 2021 Synthesis:
Mapping GTECH to specific cells from your Target Library.
