Synopsys Design Compiler Tutorial 2021 -

Before launching Design Compiler, create a local setup file named .synopsys_dc.setup inside your work/ directory. This file initializes the tool variables automatically upon startup.

: Create a dedicated folder for each project to manage generated files.

The following section breaks down the end-to-end synthesis flow performed inside a standard Design Compiler script. Step 1: Reading and Analyzing the RTL synopsys design compiler tutorial 2021

# Library paths – 2021 format uses search_path set search_path [list . ../rtl ../libs $SYNOPSYS_DC_HOME/libraries/syn]

set tech_path "/path/to/tech_libs" set lib_path "/path/to/cell_libs" # Target Library (for mapping logic gates) set target_library [list $lib_path/sc_max.db] # Link Library (includes target library + standard cells + IP) set link_library [list * $target_library $tech_path/io_max.db] # Symbol Library (for schematic viewing) set symbol_library [list $tech_path/generic.sdb] Use code with caution. 3. The Synthesis Flow Steps Before launching Design Compiler, create a local setup

The standard compile command performs logic optimization and technology mapping.

Before launching the tool, ensure your working directory contains the necessary setup files. .synopsys_dc.setup The following section breaks down the end-to-end synthesis

DC applies Boolean structuring and mapping algorithms to optimize the design logic based on your user constraints.

For complex designs, compile_ultra is the industry standard. It enables advanced optimization algorithms, including:

# Define the target technology library (the standard cells you are mapping to) set target_library slow.db
