Circuit design

The process of circuit design can cover systems ranging from complex electronic systems all the way down to the individual transistors within an integrated circuit. For simple circuits the design process can often be done by one person without needing a planned or structured design process, but for more complex designs, teams of designers following a systematic approach with intelligently guided computer simulation are becoming increasingly common. In integrated circuit design automation, the term "circuit design" often refers to the step of the design cycle which outputs the schematics of the integrated circuit. Typically this is the step between logic design and physical design.

A technical proposal may be written to meet the requirements of the customer specification. The next stage involves synthesising on paper a schematic circuit diagram, an abstract electrical or electronic circuit that will meet the specifications. A calculation of the component values to meet the operating specifications under specified conditions should be made. Simulations may be performed to verify the correctness of the design.

A breadboard or other prototype version of the design for testing against specification may be built. It may involve the making of any alterations to the circuit to achieve compliance. A choice as to a method of construction as well as all the parts and materials to be used must be made. There is a presentation of component and layout information to draughtspersons, and layout and mechanical engineers, for prototype production. This is followed by the testing or type-testing a number of prototypes to ensure compliance with customer requirements. Usually there is a signing and approval of the final manufacturing drawings and there may be post-design services (obsolescence of components etc.).
