Synopsys Design Compiler: An Introduction
Synopsys Design Compiler is a family of RTL synthesis products that enables users to meet today's design challenges with concurrent optimization of timing, area, power and test. It can transform high-level descriptions of digital circuits written in HDL (Hardware Description Language) into gate-level netlists based on a technology library. In this article, we will introduce some of the features and benefits of Synopsys Design Compiler and how it can help you achieve your design goals.
What is RTL Synthesis?
RTL synthesis is the process of converting a behavioral or structural description of a digital circuit into a lower-level representation that is closer to the physical implementation. RTL stands for Register Transfer Level, which is a level of abstraction that describes the data flow and logic operations between registers in a circuit. RTL synthesis can perform various optimizations on the input description, such as logic minimization, constant propagation, dead code elimination, etc., to improve the quality of results (QoR) in terms of timing, area, power and testability.
Why Use Synopsys Design Compiler?
Synopsys Design Compiler is the industry's most comprehensive synthesis solution that offers several advantages over other synthesis tools. Some of the benefits are:
- Concurrent optimization of timing, area, power and test: Design Compiler can perform simultaneous optimization of multiple design objectives, such as minimizing delay, reducing area, lowering power consumption and enhancing testability. This can help you meet your design specifications and constraints more efficiently and effectively.
- Topographical technology: Design Compiler includes innovative topographical technology that enables a predictable flow resulting in faster time to results. Topographical technology provides timing and area prediction within 10% of the results seen post-layout, enabling designers to reduce costly iterations between synthesis and physical implementation.
- Scalable infrastructure: Design Compiler has a scalable infrastructure that delivers 2X faster runtime on quad-core platforms. It can also leverage cloud computing resources to accelerate synthesis tasks and reduce turnaround time.
- Support for advanced process nodes: Design Compiler supports the latest technologies and standards for the process nodes 5nm and below. It can handle complex design rules, low-power techniques, multi-voltage domains, etc., to ensure compatibility and reliability of your designs.
- Integration with other Synopsys tools: Design Compiler is part of the Synopsys RTL synthesis solution, which includes Power Compiler, DesignWare, PrimeTime, and DFTMAX. It can also produce physical guidance to IC Compiler, the place-and-route solution for tighter correlation to layout and faster placement runtime. This enables a seamless and consistent design flow from RTL to GDSII.
How to Use Synopsys Design Compiler?
Synopsys Design Compiler has two user interfaces: Design Vision and dc_shell. Design Vision is a graphical user interface (GUI) that provides a convenient and intuitive way to interact with the tool. dc_shell is a command-line interface (CLI) that allows more flexibility and automation of synthesis tasks. You can use either interface depending on your preference and needs.
To use Synopsys Design Compiler, you need to have the following inputs:
- An HDL description of your design in Verilog or VHDL.
- A technology library that contains the information about the cells, wires and interconnects available in your target technology.
- A constraint file that specifies the timing, area, power and test requirements and limitations of your design.
The output of Synopsys Design Compiler is a gate-level netlist that meets your design objectives and constraints. You can also generate reports and views that show various aspects of your synthesized design, such as timing analysis, area estimation, power analysis, testability analysis, etc.
