Auto-router
In electronic design, wire routing, commonly called simply routing, is a step in the design of printed circuit boards (PCBs) and integrated circuits (ICs). It builds on a preceding step, called placement, which determines the location of each active element of an IC or component on a PCB. After placement, the routing step adds wires needed to properly connect the placed components while obeying all design rules for the IC. Together, the placement and routing steps of IC design are known as place and route. The task of all routers is the same. They are given some pre-existing polygons consisting of pins (also called terminals) on cells, and optionally some pre-existing wiring called preroutes. Each of these polygons are associated with a net, usually by name or number. The primary task of the router is to create geometries such that all terminals assigned to the same net are connected, no terminals assigned to different nets are connected, and all design rules are obeyed.

Allegro PCB Router
Specctra is a commercial PCB auto-router originally developed by John F. Cooper and David Chyan of Cooper & Chyan Technology, Inc. (CCT) in 1989. The company and product were taken over by Cadence Design Systems in May 1997. Since its integration into Cadence's Allegro PCB Editor, the name of the router is Allegro PCB Router. The latest version is 17.4 – 22.1 (20 October 2022). Specctra routes boards by presenting graphical data using a "shape-based" technology which represents graphical objects not as a set of points-coordinates but more compact. This increases the efficiency of routing printed circuit boards with a high density of components, provides automatic routing of the same chain of tracks of different widths, and more. Specctra uses adaptive algorithms implemented in multiple trace runs. The routing is carried out in three stages: # preview routing # autoroute # additional processing of autoroute results On the first pass, the connection of all conductors is per ...

Electronic Design Automation
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), is a category of software tools for designing Electronics, electronic systems such as integrated circuits and printed circuit boards. The tools work together in a Design flow (EDA), design flow that chip designers use to design and analyze entire semiconductor chips. Since a modern semiconductor chip can have billions of components, EDA tools are essential for their design; this article in particular describes EDA specifically with respect to integrated circuits (ICs). History Early days The earliest electronic design automation is attributed to IBM with the documentation of its IBM 700/7000 series, 700 series computers in the 1950s. Prior to the development of EDA, integrated circuits were designed by hand and manually laid out. Some advanced shops used geometric software to generate tapes for a Gerber format, Gerber photoplotter, responsible for generating a monochromatic ex ...

Multi-chip Module
A multi-chip module (MCM) is generically an electronic assembly (such as a package with a number of conductor terminals or Lead (electronics), "pins") where multiple integrated circuits (ICs or "chips"), semiconductor Die (integrated circuit), dies and/or other discrete components are integrated, usually onto a unifying substrate, so that in use it can be treated as if it were a larger IC. Other terms for MCM packaging include "heterogeneous integration" or "hybrid integrated circuit". The advantage of using MCM packaging is it allows a manufacturer to use multiple components for modularity and/or to improve yields over a conventional monolithic IC approach. A Flip Chip Multi-Chip Module (FCMCM) is a multi-chip module that uses flip chip technology. A FCMCM may have one large die and several smaller dies all on the same module. Overview Multi-chip modules come in a variety of forms depending on the complexity and development philosophies of their designers. These can range from ...

Racal-Redac
Racal Electronics plc was a British electronics company that was founded in 1950. Listed on the London Stock Exchange and once a constituent of the FTSE 100 Index, Racal was a diversified company, offering products including voice recorders and data recorders, point of sale terminals, laboratory instruments and military electronics, including radio and radar. At its height it was the third largest British electronics firm; it operated worldwide and employed over 30,000 people at its height. It was the parent company of Vodafone, before the mobile telephony provider was sold in 1991. Racal was bought by Thomson-CSF (now called Thales Group) in 2000. The purchase was expected to roughly double the size of the French defence giant's operations in the UK, a country that already represented one of its biggest export markets in Europe. In 2001, Racal Instruments Inc. became an independent company after a leveraged buyout from Thales. In 2004, it was acquired by EADS North America De ...

Bloodhound Router
The bloodhound is a large scent hound, originally bred for hunting deer, wild boar, rabbits, and since the Middle Ages, for tracking people. Believed to be descended from hounds once kept at the Abbey of Saint-Hubert, Belgium, in French it is called . This breed is famed for its ability to discern human scent over great distances, even days later. Its extraordinarily keen sense of smell is combined with a strong and tenacious tracking instinct, producing the ideal scent hound. It is used by police and law enforcement all over the world to track escaped prisoners, missing people, and lost pets. Appearance Bloodhounds weigh from 36 to 72 kg (80 to 160 lbs). They are 58 to 70 cm (23 to 27 inches) tall at the withers. According to the AKC standard for the breed, larger dogs are preferred by conformation judges. Acceptable colors for bloodhounds are black, liver, and red. Bloodhounds possess an unusually large skeletal structure with most of their weight c ...

Area Router
Area is the measure of a region's size on a surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while ''surface area'' refers to the area of an open surface or the boundary of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). Two different regions may have the same area (as in squaring the circle); by synecdoche, "area" sometimes is used to refer to the region, as in a "polygonal area". The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square ...

Switchbox Router
A KVM switch (with KVM being an abbreviation for "keyboard, video, and mouse") is a hardware device that allows a user to control multiple computers from one or more sets of keyboards, video monitors, and mouse. Name Switches to connect multiple computers to one or more peripherals have had multiple names. The earliest name was Keyboard Video Switch (KVS). With the advent of the mouse, the Keyboard, Video and Mouse (KVM) switch became popular. The name was introduced by Remigius Shatas, the founder of Cybex (now Vertiv), a peripheral switch manufacturer, in 1995. Some companies call their switches Keyboard, Video, Mouse and Peripheral (KVMP). Types USB keyboards, mice, and I/O devices are the most common devices connected to a KVM switch. The classes of KVM switches discussed below are based on different types of core technologies, which vary in how the KVM switch handles USB I/O devices—including keyboards, mice, touchscreen displays, etc. (USB-HID = USB Human Int ...
