PCB model definitions are similarly stored in a PCB Library ( *.PcbLib), where its constituent models are linked to by the symbol (component) definitions in a Schematic Library. etc.,) are collectively stored in a Schematic Library file ( *.SchLib) that can be loaded in CircuitStudio. Schematic component definitions (composed of a symbol, model links, parameters. In CircuitStudio, this schematic representation of the component also provides a range of optional properties, parameters and links to a PCB footprint pattern – or more correctly, a 2D and/or 3D model that physically represents the component on a PCB. The initial task in this part of the design process is generally capturing its circuitry in a schematic, where a placed component provides a graphical symbol that includes the component’s electrical connection points defined by pins. Components are ‘wired’ together to form the complete design. In its common form, a component is generally composed of a logical symbol that is applied to the design’s schematic and a footprint pattern (model) that will physically represent the component on the PCB.

A component is the general name given to a part that can be placed into an electronic design during the design capture process.
