Circuit design.

The process of circuit design can cover systems ranging from national power grids 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 planed 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.
As circuit design is the process of working out the physical form that an electronic circuit will take, the result of the circuit design process is the instructions on how to construct the physical electronic circuit.
This will normally take the form of blueprints describing the size, shape, connectors, etc in use, and artwork or CAM file for manufacturing a printed circuit board or Integrated circuit.
