In electric power systems design, a design drawing known as a one-line diagram is often utilised to symbolize substations, distribution methods as well as entire electrical power grids. All these diagrams simplify and compress the details which would be repeated on each stage of a three-phase system, showing only 1 component instead of three. Electrical diagrams such as switchgear often have common device functions designate by standard function numbers.
Schematic diagrams have been used extensively in repair manuals to help users understand the interconnections of parts, and also to give graphical training to assist in rebuilding and simplifying mechanical assemblies. Many motorcycle and automotive repair manuals devote a significant number of webpages into schematic diagrams.
A semi-schematic diagram combines a number of these abstraction of a purely schematic diagram with different elements exhibited as realistically as you can, for various factors. It's a compromise involving a purely subjective diagram (e.g. the schematic of the Washington Metro) along with a completely pragmatic representation (e.g. the corresponding aerial view of Washington).
In electronic design automation, until the 1980s schematics were the only formal representation for circuits. More recently, together with the progress of computer technologies, other specimens were introduced and specialized computer languages have been developed, as using the explosive development of the complexity of electronic circuits, conventional schematics have become less functional.
Schematics for digital circuits are prepared by designers utilizing EDA (electronic design automation) tools called schematic capture applications or schematic entry tools. These tools go beyond easy drawing of connections and devices. Normally they are incorporated into the whole IC design flow and linked to other EDA tools for simulation and verification of this circuit under design.
In electronic and electrical industry, a schematic diagram is often utilised to refer to the plan of equipment. Schematic diagrams are usually used for the maintenance and repair of electronic and electromechanical systems.  Original schematics were done by hand, with standardized templates or pre-printed adhesive symbols, but now electronic design automation applications (EDA or"electric CAD") is often employed.
A schematic, or schematic diagram, is a representation of those components of a system using abstract, picture symbols rather than realistic pictures. A schematic generally communicates all details that aren't pertinent to the advice that the cheque is meant to communicate, and may add unrealistic elements that aid comprehension. As an example, a subway map intended for passengers could represent a subway station using a dot; the dot does not resemble the actual station at all but provides the viewer info without any unnecessary visual clutter. A schematic diagram of this compound process uses symbols to represent the valves, ducts, valves, pumps, and other equipment of the system, highlighting their interconnection paths and suppressing physical information. In an electronic circuit diagram, the design of the symbols may not resemble the design from the circuit. In the schematic diagram, the emblematic components are organized to be more easily interpreted by the viewer.
