Waveform Viewer
A waveform viewer is a software tool for viewing the signal levels of either a digital circuit, digital or analog circuit design.Janick Bergeron, ''Writing Testbenches: Functional verification of HDL Models'', Kluwer Academic Publishers, 2000 Waveform viewers comes in two varieties: # simulation waveform viewers for displaying signal levels of simulated design models, and # in-circuit waveform viewers for displaying signal levels captured in-circuit while debugging or testing hardware boards (see also waveform monitor) Simulation waveform viewers In integrated circuit design, waveform viewers are typically used in conjunction with a simulation (EDA), simulation. A waveform view allows an IC designer to see the signal transitions over time and the relation of those signals with other signals in an IC design, which is typically written in a hardware description language. Simulators can be used to interactively capture wave data for immediate viewing on a waveform viewer; however, fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Tool
A programming tool or software development tool is a computer program that is used to software development, develop another computer program, usually by helping the developer manage computer files. For example, a programmer may use a tool called a source code editor to edit source code files, and then a compiler to convert the source code into machine code files. They may also use Build automation, build tools that automatically package executable program and data files into shareable package manager, packages or Installation (computer programs), install kits. A set of tools that are run one after another, with each tool feeding its output to the next one, is called a toolchain. An integrated development environment (IDE) integrates the function of several tools into a single program. Usually, an IDE provides a source code editor as well as other built-in or Plug-in (computing), plug-in tools that help with compiler, compiling, debugging, and software test, testing.

Teradyne
Teradyne, Inc. is an American automatic test equipment (ATE) designer and manufacturer based in North Reading, Massachusetts. Its high-profile customers include Samsung, Qualcomm, Intel, Analog Devices, Texas Instruments and IBM. History Teradyne was founded by Alex d'Arbeloff and Nick DeWolf, who were classmates at the Massachusetts Institute of Technology (MIT) in the late 1940s. The men founded Teradyne in 1960, and set up shop in rented space above Joe and Nemo's hotdog stand in downtown Boston. The name, Teradyne, was intended to represent a very forceful presence. 1,000,000,000,000 dynes = 10 meganewtons (2,248,089 pounds-force or 1,019,716 kilograms-force). d'Arbeloff and DeWolf knew that testing electronic components in high-volume production would reach a bottleneck, unless the tasks performed by technicians and laboratory instruments could be automated. Their business plan involved a new breed of "industrial-grade" electronic test equipment, known for its tec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LabWindows/CVI
LabWindows/CVI (CVI is short for C for Virtual Instrumentation) is an ANSI C programming environment for test and measurement developed by National Instruments. The program was originally released as LabWindows for DOS in 1987, but was soon revisioned (and renamed) for the Microsoft Windows platform. The current version of LabWindows/CVI (commonly referred to as CVI) is 2020. LabWindows/CVI uses the same libraries and data-acquisition modules as the better known National Instrument product LabVIEW and is thus highly compatible with it. LabVIEW is targeted more at domain experts and scientists, and CVI more towards software engineers that are more comfortable with text-based linear languages such as C. Release history Starting with LabWindows/CVI 8.0, major versions are released around the first week of August, to coincide with the annual National Instruments conference NI Week, and followed by a bug-fix release the following February. In 2009, National Instruments started ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tektronix
Tektronix, Inc., historically widely known as Tek, is an American company best known for manufacturing test and measurement devices such as oscilloscopes, logic analyzers, and video and mobile test protocol equipment. Originally an independent company, it is now a subsidiary of Fortive, a Corporate spin-off, spinoff from Danaher Corporation. History 1946–1954 The company traces its roots to the electronics revolution that immediately followed World War II. It was founded in December 1945 as Tekrad. The name was similar to that of a California company, Techrad, so in 1946, the four partners, Howard Vollum, Melvin Jack Murdock, Jack Murdock and Miles Tippery, who had both served in the United States Coast Guard, Coast Guard, and accountant Glenn McDowell, formed Tektronix, Inc. Each contributed an initial $2,600 for equal shares. Howard Vollum had graduated in 1936 from Reed College with a degree in physics and a keen interest in oscilloscopes, then worked as a radio tech ...

Automatic Test Equipment
Automatic test equipment or automated test equipment (ATE) is any apparatus that performs tests on a device, known as the device under test (DUT), equipment under test (EUT) or unit under test (UUT), using automation to quickly perform measurements and evaluate the test results. An ATE can be a simple computer-controlled Multimeter, digital multimeter, or a complicated system containing dozens of complex test instruments (real or simulated electronic test equipment) capable of automatically testing and diagnosing faults in sophisticated electronic packaged parts or on wafer testing, including system on chips and integrated circuits. ATE is widely used in the electronic manufacturing industry to test electronic components and systems after being fabricated. ATE is also used to test avionics and the electronic modules in automobiles. It is used in military applications like radar and wireless communication. In the semiconductor industry Semiconductor ATE, named for testing se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Acquisition
Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms ''DAS,'' ''DAQ,'' or ''DAU,'' typically convert analog waveforms into digital values for processing. The components of data acquisition systems include: * Sensors, to convert physical parameters to electrical signals. * Signal conditioning circuitry, to convert sensor signals into a form that can be converted to digital values. * Analog-to-digital converters, to convert conditioned sensor signals to digital values. Data acquisition applications are usually controlled by software programs developed using various general purpose programming languages such as Assembly, BASIC, C, C++, C#, Fortran, Java, LabVIEW, Lisp, Pascal, etc. Stand-alone data acquisition systems are often called data loggers. There are also ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logic Analyzer
A logic analyzer is an electronic instrument that captures and displays multiple logic signals from a digital system or digital circuit. A logic analyzer may convert the capture into timing diagrams, protocol decodes, state machine traces, opcodes, or may correlate opcodes with source-level software. Logic analyzers have advanced triggering capabilities, and are useful when a user needs to see the timing relationships between many signals in a digital system. Overview Presently, there are three distinct categories of logic analyzers available on the market: * Modular LAs, which consist of both a chassis or mainframe and logic analyzer modules. The mainframe/chassis contains the display, controls, control computer, and multiple slots into which the actual data-capturing hardware is installed. The modules each have a specific number of channels, and multiple modules may be combined to obtain a very high channel count. While modular logic analyzers are typically more expensive, ...

Digital Circuit
In theoretical computer science, a circuit is a model of computation in which input values proceed through a sequence of gates, each of which computes a function. Circuits of this kind provide a generalization of Boolean circuits and a mathematical model for digital logic circuits. Circuits are defined by the gates they contain and the values the gates can produce. For example, the values in a Boolean circuit are Boolean values, and the circuit includes conjunction, disjunction, and negation gates. The values in an integer circuit are sets of integers and the gates compute set union, set intersection, and set complement, as well as the arithmetic operations addition and multiplication. Formal definition A circuit is a triplet (M, L, G), where * M is a set of values, * L is a set of gate labels, each of which is a function from M^ to M for some non-negative integer i (where i represents the number of inputs to the gate), and * G is a labelled graph, labelled directed acyclic gra ...

Binary Code
A binary code represents plain text, text, instruction set, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number, binary number system. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc. For example, a binary string (computer science), string of eight bits (which is also called a byte) can represent any of 256 possible values and can, therefore, represent a wide variety of different items. In computing and telecommunications, binary codes are used for various methods of encoding data, such as character strings, into bit strings. Those methods may use fixed-width or variable-length code, variable-width strings. In a fixed-width binary code, each letter, digit, or other character is represented by a bit string of the same length; that bit string, interpreted as a binary number, is usually displayed in code tables in octal, decimal ...
