These tools go beyond easy drawing of devices and connections. Normally they're incorporated into the whole IC design flow and also connected to additional EDA tools for verification and simulation of the circuit under design.
A semi-schematic diagram combines a number of these abstraction of a just schematic diagram along with other components displayed as realistically as possible, for various factors. It is a compromise involving a purely subjective diagram (e.g. the design of the Washington Metro) along with a completely realistic representation (e.g. the corresponding aerial view of Washington).
In electronic design automation, even until the 1980s schematics were practically the only formal representation for circuits. More recently, with the advancement of computer technology, other specimens have been introduced and technical computer languages have been developed, because using all the explosive growth of the complexity of digital circuits, traditional schematics have become less practical. For instance, hardware description languages are indispensable for modern digital circuit design.
In electric power systems layout, a schematic drawing called a one-line diagram is often used to symbolize substations, distribution systems as well as whole electrical power grids. All these diagrams compress and simplify the facts that would be repeated on each individual phase of a three-phase method, showing just one component rather than three. Electrical diagrams for switchgear frequently have common apparatus functions designate by standard function amounts.
Schematic diagrams have been used extensively in repair guides to help users understand the interconnections of components, and also to offer graphical instruction to help out with rebuilding and simplifying mechanical assemblies. Many automotive and motorcycle repair manuals give a significant number of pages into schematic diagrams.
A schematic, or schematic diagram, is a representation of these components of a system utilizing abstract, graphic symbols instead of realistic pictures. A schematic usually omits all details which aren't relevant to the advice the schematic is meant to convey, and might add unrealistic elements that aid comprehension. As an example, a subway map intended for passengers might represent a subway station using a scatter; the dot doesn't resemble the actual station whatsoever but gives the viewer information without unnecessary visual clutter. A schematic diagram of the compound process utilizes symbols to represent the vessels, piping, valvesand pumps, and other elements of the system, emphasizing their interconnection paths and suppressing physiological details. In a digital circuit structure, the layout of these symbols may not resemble the layout in the circuit. In the schematic diagram, the symbolic elements are arranged to be easily interpreted by the viewer.
In electrical and electronic sector, a schematic diagram is often utilized to describe the design of equipment.  Initial schematics have been done by hand, using standardized templates or off-the-shelf adhesive symbols, but now electronic design automation applications (EDA or"electrical CAD") can be employed.
