This standard defines a defect coverage accounting method based on simulation models for defects observed within integrated circuits (ICs). The portion of all possible defects that are detected, or "covered", by tests of analog and mixed-signal circuits depends, in practice, on many factors (detectability, defect characteristics, detection threshold margin, measurement resolution, operating point, test patterns, etc.), which this standard considers as it defines how to report coverage. This… read more standard focuses on defects in analog functions. In this context, "defect" is an observable unintended physical change in a circuit, and an "analog function" means a function that has input, internal, or output signals with meaningful values in a defined continuous range, and the function has at least one parametric performance that is sufficiently non-deterministic that its test has upper and/or lower limits (the limits may be real numbers or quantized digital equivalents). This standard considers redundancy, since most analog circuits have redundancy and defect tolerance, intentional or not. This standard does not consider combinations of variations that could result in a circuit failing to meet all its specifications - that is the subject of Monte Carlo simulations during design for yield and multi-parameter analog defect modeling. The defects considered here are applicable to purely digital circuits too, though typically a simplified fault model (stuck-at, for instance) is utilized for digital functions. Thus, this standard assumes the topic of stuck-at fault coverage accounting is addressed for digital circuits by IEEE1804 "Standard for Fault Accounting and Coverage Reporting to Digital Modules." read less

This standard defines the IEEE 1076.1™ language, a hardware description language for the description and the simulation of analog, digital, and mixed-signal systems. Informally called VHDL-AMS (VHSIC Hardware Description Language for Analog and Mixed-Signal, where VHSIC stands for Very High Speed Integrated Circuits), the language is built on the IEEE 1076™ (VHDL) language and extends it to provide capabilities of writing and simulating analog and mixed-signal models.

The material presented in this standard is intended to provide common terminology and test methods for the testing and evaluation of analog-to-digital converters (ADCs). This standard considers only those ADCs whose output values are extracted (sampled) and then digitized at known time intervals. In general, this quantization is assumed to be nominally uniform (the input-output transfer curve is approximately a straight line) as discussed further in 1.4, and the sampling is assumed to be at a… read more nominally uniform rate. Some but not all of the test methods in this standard can be used for ADCs that are designed for non-uniform quantization. read less

This standard defines terminology and test methods to clearly document prevalent world-wide terms used to describe and test digital-to-analog converters (DACs). Although principally applicable to monolithic, hybrid, module DACs, most of the definitions and test procedures can be applied to systems containing DACs.

Telecommunications transmission measuring equipment for measuring the analog transmission characteristics of networks and circuits, including digitally encoded analog signals, analog components of digital services, e.g. ISDN, HDSL, etc., and other complex signals.

定价： 169元 / 折扣价： 144 元

This standard specifies requirements for analog signals, emanating from electronic voltage and current transducers, that are inputted to protective relays. These requirements include signal level, frequency bandwidth, and dynamic range. The standard recognizes that other substation electronic devices utilizing voltage and current waveform measurements may connect to the same transducers.

This standard defines a collection of VHDL 1076.1 packages, compatible with IEEE Std 1076.1(TM),along with recommendations for conforming use, in order to facilitate the interchange of simulation models of physical components and subsystems. The packages include the definition of standard types, subtypes, natures, and constants for modeling in multiple energy domains (electrical, fluidic, mechanical, etc.) The packages are intended for use primarily in the modeling of multiple energy domain systems. The range of operation of the packages is not defined in this standard, but is intended to be valid across a wide range of disciplines and applications.
