Initially, electronic circuits were designed by hand. The entire process was translated from electronics to graphics manually. Automation of design and drafting started in the mid-70s. This ground breaking invention advocated chip design. Soon, the complexity in chip designs increased leading to increased access to design verification tools. Most giant companies first used design automation tools internally, but gradually, they started focusing on it as a business.

Circuit Design

The process includes systems from individual transistors to complex electronic systems within an integrated circuit. One person can easily design a simple circuit. There is no need of a planned and structured design process. But in case of complex designs, a team of designers follows a systematic approach. They use computer guided simulation to process the designs.


Stages in Design Automation

  • Liaising with the customer
  • A technical proposal submitted by the customer stating all the requirements
  • Preparing a schematic circuit diagram on paper for synthesis – this is an abstract electronic circuit as per the customer’s specifications
  • Calculating the component values to meet the operating specifications under specified conditions
  • Performing simulations to verify the correctness of design
  • A trial version of the design for testing against specifications.
  • Choosing the necessary parts and materials.
  • A presentation of the components to the engineers and draughtsmen.
  • Testing a number of prototypes to ensure compliance with customer requirements.
  • A final approval and signing of manufacturing drawings.


Computer aided design software and other design tools like design automation have become very common in recent years. These programmes have evolved during years and have enormous capabilities. However, the companies that need them and use them have not developed their design practices accordingly; they take some time to adopt the new tools. The provider companies already own licenses to provide the tools, but the user companies have to spend a little extra money to take advantage of the tools. In fact, the new technologies reduce both time-to-market and the quality of their goods.


Automating the Process

CAD tools help to automate design tasks and are beneficial for companies that make custom products and manufacture goods in large volumes.

  • With CAD tools, it is possible to automate repetitive design tasks and generate any number of variations of a model. The project is set up only once and can be run again and again.
  • The design knowledge can be captured and reused so time and money is saved.
  • Manual errors can be minimized by incorporating design rules.
  • Design time can be reduced considerably when new variants are introduced.
  • Variations can be created quickly and easily.
  • Several tasks can be automated and streamlined with a few clicks of the mouse.
  • Use a task-scheduler for automating batches.
  • Automation can be customized using standard automation tools.
  • Specific functions can be automated with the help of built-in application programming.


On the whole, design automation has made it very simple to design electronic systems such as printed circuit boards and electronic circuits. Many engineering and architectural firms around the world have started automating the design of construction projects. It consists of convenient, usable and affordable hardware and software.
