Electronic design automation software programs include schematic capture programs and printed circuit board design programs.

A popular circuit implementing a second order active R-C filter is the Sallen-Key design, whose schematic diagram is shown here.

To define the behavior of the FPGA, the user provides a hardware description language ( HDL ) or a schematic design.

However, schematic entry can allow for easier visualisation of a design.

For example, when working on a brick-and-mortar design and construction, projects will typically progress through stages like pre-planning, conceptual design, schematic design, design development, construction drawings ( or contract documents ), and construction administration.

The process will often mirror the architectural process or schedule, moving from conceptual plan, through schematic design, design development, contract document, fabrication and installation.

In the electrical industry, a schematic diagram is often used to describe the design of equipment.

In electric power systems design, a schematic drawing called a one-line diagram is frequently used to represent substations, distribution systems or even whole electrical power grids.

One can design hardware in a VHDL IDE ( for FPGA implementation such as Xilinx ISE, Altera Quartus, Synopsys Synplify or Mentor Graphics HDL Designer ) to produce the RTL schematic of the desired circuit.

HDL simulation enabled engineers to work at a higher level of abstraction than simulation at the schematic level, and thus increased design capacity from hundreds of transistors to thousands.

A circuit design from a skilled engineer, using labor-intensive schematic-capture / hand-layout, would almost always outperform its logically-synthesized equivalent, but the productivity advantage held by synthesis soon displaced digital schematic capture to exactly those areas that were problematic for RTL synthesis: extremely high-speed, low-power, or asynchronous circuitry.

PCB layout and schematic for connector design

The VT fuze concept in the context of artillery shells originated in the UK with British researchers ( particularly Sir Samuel Curran and W. A. S. Butement, whose schematic design for a radar proximity fuze was used with only minor variations ) and was developed under the direction of physicist Merle A. Tuve at The Johns Hopkins University Applied Physics Lab ( APL ).

The calendar components are several calendar properties which create a calendar schematic ( design ).

The gate arrays were designed using a combination of internally developed simulator and placement tools, and one of the first commercial electronic design automation tools ( an application for schematic capture ) from Mentor Graphics.

The Houston NFL Holdings group came to Populous ( then HOK Sport ) to begin the schematic design for the first-ever NFL retractable roof football stadium in 1997.

Volta ordered the metals in a ' tension series ', “ that is to say in an order such that any one in the list becomes positive when in contact with any one that succeeds, but negative by contact with any one that precedes it .” A typical symbolic convention in a schematic of this circuit ( –< big >|</ big >– ) would have a long electrode 1 and a short electrode 2, to indicate that electrode 1 dominates.

Public acceptance of this scientific revolution was, and remains, uneven but the mainstream scholarly community soon arrived at a consensus, which holds today, that Genesis 1 – 11 is a highly schematic literary work representing theology / mythology rather than history.

Fig. 1 is a schematic diagram of a classical dilution refrigerator.

The only requirement is that the naming schematic used within a particular set of calculations or descriptions must be consistent ( e. g. the orbital occupied by the first electron in a p subshell could be described as m < sub ></ sub > = − 1 or m < sub ></ sub > = 0, or m < sub ></ sub > = 1, but the m < sub ></ sub > value of the other electron in that orbital must be the same, and the m < sub ></ sub > assigned to electrons in other orbitals must be different ).
