EDIF
EDIF (Electronic Design Interchange Format) is a vendor-neutral format based on S-Expressions in which to store Electronic netlists and schematics. It was one of the first attempts to establish a neutral data exchange format for the electronic design automation (EDA) industry. The goal was to establish a common format from which the proprietary formats of the EDA systems could be derived. When customers needed to transfer data from one system to another, it was necessary to write translators from one format to other. As the number of formats (''N'') multiplied, the translator issue became an ''N''-squared problem. The expectation was that with EDIF the number of translators could be reduced to the number of involved systems. Representatives of the EDA companies Daisy Systems, Mentor Graphics, Motorola, National Semiconductor, Tektronix, Texas Instruments and the University of California, Berkeley established the ''EDIF Steering Committee'' in November 1983. Later Hilary Kahn, a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hilary Kahn
Hilary J. Kahn (1943–2007) was a South African British computer scientist who spent most of her career as a professor at the University of Manchester, where she worked on computer-aided design and information modelling. Kahn participated in the development of the Manchester MU5 computer. Later she became involved in standards development and was both the chair of the Technical Experts Group and a member of the Steering Committee for the development of the EDIF (Electronic Design Interchange Format) standard. Kahn retired from Manchester in 2006 and died in 2007. Early life and education Kahn was born in 1943 in Cape Town, South Africa and moved in 1960 to England; she said later that she did so to pursue her education and escape the politics of her native country. She attended the University of London and studied classics, after which she attended a post-graduate diploma course in computing at the Newcastle University, where she was first exposed to working with the English ...

Netlist
In electronic design, a netlist is a description of the connectivity of an electronic circuit. In its simplest form, a netlist consists of a list of the electronic components in a circuit and a list of the nodes they are connected to. A network (net) is a collection of two or more interconnected components. The structure, complexity and representation of netlists can vary considerably, but the fundamental purpose of every netlist is to convey connectivity information. Netlists usually provide nothing more than instances, nodes, and perhaps some attributes of the components involved. If they express much more than this, they are usually considered to be a hardware description language such as Verilog or VHDL, or one of several languages specifically designed for input to simulators or hardware compilers (such as SPICE analog simulation netlists). Types of netlists Netlists can be: * Physical (based upon physical connections) or logical (based upon logical connections) ** For ...

S-Expression
In computer programming, an S-expression (or symbolic expression, abbreviated as sexpr or sexp) is an expression in a like-named notation for nested list (tree-structured) data. S-expressions were invented for and popularized by the programming language Lisp, which uses them for source code as well as data. In the usual parenthesized syntax of Lisp, an S-expression is classically definedJohn McCarthy (1960/2006)Recursive functions of symbolic expressions. Originally published in Communications of the ACM. as # an atom of the form ''x'', or # an expression of the form (''x'' . ''y'') where ''x'' and ''y'' are S-expressions. This definition reflects LISP's representation of a list as a series of "cells", each one an ordered pair. In plain lists, ''y'' points to the next cell (if any), thus forming a list. The recursive clause of the definition means that both this representation and the S-expression notation can represent any binary tree. However, the representation can in princi ...

International Electrotechnical Commission
The International Electrotechnical Commission (IEC; in French: ''Commission électrotechnique internationale'') is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies – collectively known as " electrotechnology". IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy as well as many others. The IEC also manages four global conformity assessment systems that certify whether equipment, system or components conform to its international standards. All electrotechnologies are covered by IEC Standards, including energy production and distribution, electronics, magnetics and electromagnetics, electroacoustics, multimedia, telecommunication and medical technology, as well as associated general disciplines suc ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Original Equipment Manufacturer
An original equipment manufacturer (OEM) is generally perceived as a company that produces non-aftermarket parts and equipment that may be marketed by another manufacturer. It is a common industry term recognized and used by many professional organizations such as SAE International, ISO, and others. However, the term is also used in several other ways, which causes ambiguity. It sometimes means the maker of a system that includes other companies' subsystems, an end-product producer, an automotive part that is manufactured by the same company that produced the original part used in the automobile's assembly, or a value-added reseller.Ken Olsen: PDP-1 and PDP-8 (page 3) , economicadventure.com Automotive parts When referring to auto parts, OEM refers to the manufact ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
