Design Compiler Tutorial 2021: Synopsys

Logic synthesis transforms an abstract behavioral description (written in Verilog, SystemVerilog, or VHDL) into a structural gate-level implementation. This process is constraint-driven, meaning the tool optimizes the logic to meet specific timing, area, and power goals. Synthesis consists of three main steps:

set TARGET_LIBRARY [list "$TECH_LIB/slow.db"] set LINK_LIBRARY [list "*" $TARGET_LIBRARY] set SYMBOL_LIBRARY [list "$TECH_LIB/symbol.sdb"]

The create_clock command is the cornerstone of timing constraints. For example: synopsys design compiler tutorial 2021

: Check for "unresolved references" which indicate missing modules. 2. Apply Constraints

: This file is critical; it defines your search paths and links to your technology libraries ( target_library link_library Target Library For example: : Check for "unresolved references" which

Comprehensive Synopsys Design Compiler Tutorial Synopsys Design Compiler (DC) is the industry-standard tool for RTL synthesis. It translates your Hardware Description Language (HDL) code, such as Verilog or VHDL, into a technology-specific gate-level netlist. This tutorial guides you through the complete synthesis flow using the modern Topographical mode. 1. Synthesis Concepts and Modes

Synopsys Design Compiler Tutorial 2021: A Comprehensive Guide It translates your Hardware Description Language (HDL) code,

You can read files using either the read_verilog / read_sverilog commands, or the safer analyze and elaborate combination. The analyze/elaborate method allows parameter optimization before building the design structure.

It is highly recommended to use ( compile_ultra -topographical ). By using a physical technology library (floorplan information), it offers near-perfect correlation with Place and Route tools (ICC2) regarding timing and area, reducing iterations. 4.2 Power Optimization (Low Power Flow) DC 2021 supports advanced power optimization: Clock Gating: Automatically inserted by compile_ultra .
