In electric power systems layout, a design drawing known as a one-line diagram is frequently utilised to represent substations, distribution systems or even entire electric power grids. All these diagrams simplify and compress the facts which would be replicated on each individual phase of a three-phase method, revealing just 1 component instead of three. Electrical diagrams such as switchgear often have common apparatus functions designate by regular function numbers.
These tools go beyond easy drawing of connections and devices. Usually they are integrated into the whole IC design flow and connected to additional EDA tools for simulation and verification of this circuit under design.
In electrical and electronic sector, a design diagram is frequently used to refer to the design of equipment. Schematic diagrams are usually used for the maintenance and repair of electronic and electromechanical systems.  Original schematics have been done by hand, using standardized templates or off-the-shelf adhesive symbols, but today electronic design automation applications (EDA or"electrical CAD") is often employed.
A schematic, or schematic diagram, is a representation of those elements of a system utilizing abstract, picture symbols as opposed to realistic images. A schematic generally communicates all details that aren't relevant to the advice that the cheque is meant to communicate, and may add unrealistic components that aid comprehension. For instance, a subway map meant for passengers can represent a subway station using a scatter; the scatter doesn't resemble the actual station whatsoever but gives the viewer info without unnecessary visual clutter. A schematic diagram of this compound procedure utilizes symbols to represent the valves, ducts, valvesand pumps, and other elements of the machine, highlighting their interconnection controlling and paths physiological information. In a digital circuit design, the design of the symbols might not resemble the design in the circuit. From the schematic diagram, the symbolic elements are arranged to be more easily interpreted by the viewer.
Schematic diagrams have been used extensively in repair guides to help users understand the interconnections of parts, and also to present graphical instruction to assist in rebuilding and simplifying mechanical assemblies. Many motorcycle and automotive repair manuals devote a substantial number of webpages into schematic diagrams.
In electronic design automation, even until the 1980s schematics were practically the sole proper representation for circuits. More recently, with the progress of computer engineering, other representations were introduced and technical computer languages were developed, since using the explosive growth of the complexity of electronic circuits, traditional schematics have become less functional.
A semi-schematic diagram combines a number of these abstraction of a just schematic diagram along with other elements displayed as realistically as you can, for various reasons.
