CAD: Its Role in Electronic Design

CAD or computer aided design is a software that helps developers to create products. On the other hand, EDA of electronic design automation and ECAD or electronic computer aided design are software that are specific to CAD and used for electronic designs. In the field of electrical engineering, CAD has been very essential on the ongoing process of manufacturing microprocessors and other complex electronics like PCBs or printed circuit boards. The software offers a large number of functionality and tools that help electronic companies in making their products in today’s age of information technology.

The main benefit of the software is that designs are directly converted to a production machines format. This removes the possibility for human error. At the same time, this helps keep down costs and improve quality, especially on projects and larger scale designs.


ECAD and Its Role

Before the electronic device gets into the production line, the most essential tool in the design process is ECAD. This is responsible for performing the primary tasks, specially the construction of electrical schematics, as well as perform simulations, and to create physical blueprints for different electronic devices- from the latest microprocessors to the most powerful graphic processing units. It is also the main reason why electronics have advanced processors of over 2000 transistors to ones with billions.

ECAD and its Functionality

The software’s functionality can be summed up as the testing and design of complex electronics schematics on both logical and physical level. These schematics are generated and are stored in digital formal with backups, thus making it easier to distribute and modify.

When it comes to the electronic design side, ECAD programs has the ability to design electronics schematics from the ground and eventually run simulations. This helps determine how the hardware would respond as soon as an electronic input is given. This is made possible by using the software language in order to replicate logical functions that electronics goes through. For instance, if/and logic gate are visible on the schematic, the simulation will take in all inputs into the gate then perform the same processes at the application level. The program will do this for all inputs to automatically and quickly test the schematics. The majority of the programs also has the create cells that will act similarly to solid-state chips or logic gates.

Each electrical component has its own physical manifestation and the software manages this aspect thoroughly as it is concerned of the logic process. In addition to this, the ECAD software helps engineers to place the physical components that are represented in the electrical diagram. Any discrepancy, such as the lack of room or overlapping parts are noted and can be corrected before going into the manufacturing process.
