Schematic diagrams have been used widely in repair manuals to help users understand the interconnections of components, and to provide graphical instruction to assist in dismantling and rebuilding mechanical assemblies. Lots of motorcycle and automotive repair manuals give a significant number of pages to schematic diagrams.
In electronic and electrical sector, a design diagram is often utilized to refer to the plan of gear.  Original schematics have been done manually, using standardized templates or off-the-shelf glue symbols, however now electronic design automation software (EDA or"electrical CAD") is often employed.
Schematics for digital circuits are ready by designers utilizing EDA (electronic design automation) tools called schematic capture applications or schematic entry tools. These programs go beyond straightforward drawing of connections and devices. Usually they are integrated into the whole IC design flow and also linked to additional EDA tools for verification and simulation of this circuit under design.
A design, or schematic diagram, would be a representation of those components of a system using abstract, graphic symbols instead of realistic pictures. A schematic usually omits all details which aren't related to the advice the schematic is intended to convey, and may add unrealistic components that aid comprehension. As an example, a subway map meant for passengers might represent a subway station using a dot; the scatter does not resemble the true station whatsoever but gives the viewer information without any unnecessary visual clutter. A schematic diagram of a compound process utilizes symbols to represent the vessels, piping, valvesand pumps, and other elements of the system, emphasizing their interconnection controlling and paths physiological specifics. In a digital circuit design, the layout of the symbols may not resemble the design in the circuit. In the schematic diagram, the symbolic components are organized to be easily interpreted by the viewer.
A semi-schematic diagram combines some of the abstraction of a purely schematic diagram with different components exhibited as realistically as possible, for a variety of factors.
In electrical power systems design, a design drawing referred to as a one-line diagram is often utilised to symbolize substations, distribution methods as well as entire electrical power grids. All these diagrams compress and simplify the exact details which would be repeated on each stage of a three-phase system, demonstrating just one component rather than three. Electrical diagrams such as switchgear frequently have common device functions designate by regular function numbers.
In electronic design automation, even until the 1980s schematics were virtually the only proper representation for circuits. More recently, together with the progress of computer technology, other specimens have been introduced and technical computer languages have been developed, as using the explosive increase of the complexity of electronic circuits, traditional schematics have become less functional. As an example, hardware description languages are crucial for modern digital circuit design.
