ECAD (Electronic Computer-Aided Design) is software used for the development and design of electronic products and systems. It offers a robust set of tools that allow engineers to create, modify, analyze, and document electronic circuits and systems, including PCB design, ICs, PLDs, and other electronic components.

ECAD enables simulation of specific scenarios, verification of PCB functionality, and generation of production data for physical prototypes. It plays a crucial role in modern electronic design by enabling faster prototypes, efficient collaboration, and reducing time-to-market for new products.



  • Development and design of electronic products and systems:
    The purpose of ECAD is to provide tools and methods for engineers and designers that enable the creation, modification, analysis, and documentation of electronic circuits and systems.
  • Achieving accuracy, efficiency, and productivity:
    ECAD’s purpose is to meet the technical requirements of the digital age by delivering the right tools to ensure accuracy, efficiency, and productivity in the production of electronic products.
  • Wide range of applications:
    ECAD’s purpose includes designing various electronic components such as PCBs, ICs, PLDs, and other electronic devices, providing engineers with versatile options to create innovative electronic solutions.
  • Digital platform for electronic designs:
    The purpose of ECAD is to provide a digital platform where engineers can create, manipulate, and simulate electronic designs that are crucial for optimizing and refining electronic products.
  • Promoting faster prototypes and efficient collaboration:
    ECAD tools aim to expedite the prototyping process and enhance collaboration between engineers and designers, resulting in faster development and launch of new electronic products in the market.

Key ECAD features

ECAD encompasses various interconnected components, and its functions mainly aim to streamline the design and development process of electronic systems.

  • Schematic Drawing:
    A schematic drawing is the process of creating a graphical representation of an electronic circuit. Symbols represent components, and lines represent connections between them.

    ECAD provides a user-friendly interface for designing schematic drawings, allowing engineers to easily create and modify circuits.
  • PCB Layout:
    PCB layout refers to the placement and routing of electronic components on a printed circuit board.

    Components are placed, routing paths are defined, and continuous design checks are performed to ensure signal integrity, minimize noise, and optimize the layout for the most efficient production.
  • Simulation and Analysis:
    Simulation features allow engineers to verify the functionality and performance of electronic circuits before physical implementation, such as in a prototype.

    Simulations aim to assess factors like signal integrity, timing, power consumption, and thermal behavior, helping engineers optimize their designs and identify potential issues early in the development process.
  • Database Management:
    Most ECAD software has the capability to connect to databases containing pre-designed electronic components, such as resistors, capacitors, integrated circuits, and connectors.

    These databases contain detailed information about each component, including electrical characteristics, footprint, and simulation models.

    Effectively working with such databases ensures easy access to the necessary components for your specific design. Likewise, it promotes the reuse of existing as well as future designs.
  • Design Rule Check (DRC)
    DRC is a critical step in the design process, ensuring that the design complies with production constraints and specifications.

    During the design phase, ECAD tools perform automated checks of the design, verifying parameters such as minimum trace width, component spacing, and adherence to production guidelines.

    DRC helps identify potential errors or violations early in the process, preventing costly mistakes during production.
  • Data Output:
    Once the design is complete, ECAD generates the production data necessary to manufacture the finished electronic product.

    This data includes items such as PCB layout, production instructions, Bill of Materials (BOM), and assembly guidelines.

    The software’s ability to generate accurate and comprehensive data output streamlines the transition from design to final production.

Benefits of ECAD

The features of ECAD bring a plethora of benefits that can positively impact both your workflow and design process.

  • Increased productivity:
    With an ECAD tool, many tasks in the design process can be automated, reducing the time and effort required to create and modify various elements in the design.

    Features such as copy and paste, design reuse, and batch processing enable engineers to work more efficiently, ultimately resulting in increased productivity and shorter development cycles.
  • Design validation:
    ECAD’s analysis and simulation features can validate the functionality and performance of electronic designs.

    With this capability, engineers can simulate the behavior of the circuit under different conditions, identify potential issues, and subsequently optimize the design accordingly.

    This validation process minimizes the risk of costly errors and improves the quality and reliability of the final product.
  • Cost reduction:
    By validating the design for any issues using the above method, they can be identified and corrected before building physical prototypes.

    This significantly reduces costs in various aspects, such as double work, material waste, lost revenue, labor hours, and more.

    Moreover, it can help optimize the design with regard to factors like signal integrity and power consumption, leading to cost savings in both production and operation.
  • Enhanced collaboration:
    ECAD tools streamline collaboration among various team members working on different aspects of the design project. Design files can be easily shared and accessed, allowing multiple engineers to work simultaneously on different parts of the project.

    Likewise, it enables the project manager/owner to maintain oversight. The comprehensive documentation of the design process ensures accurate records and knowledge sharing within the organization.
  • Reusability:
    ECAD tools promote design reusability by maintaining and updating databases that store pre-designed components and circuits. Engineers and designers can leverage these databases to quickly assemble complex systems, reducing design time and initial effort.

    Additionally, ECAD tools allow the creation of custom components that can be reused in future projects, leading to increased efficiency and consistency in the long run.
  • Faster product launch:
    The efficient design and validation features of ECAD contribute to faster product launches.

    By optimizing the design process, minimizing errors, and facilitating more effective collaboration, ECAD enables companies to quickly bring innovative products to the market, gaining a competitive edge.
