3. Definitions, acronyms, and abbreviations
3.1 Definitions
For the purposes of this document, the following terms and definitions apply. The IEEE StandardsDictionary Online (B5] or Annex A should be consulted for terms not defined in this clause.
Abbreviated Test Language fr All Systems (ATLAS): A stylized, abbreviated English language used inthe preparation and docuentation of test requirements and test programs, which can be implementedeither manually or with automatic or semi-automatic test equipment.
NOTE-In this standard, the term ATLAS refers to any version or subset whether it is a formal standardized version ora project specific modified subset.”
argument: Input values that can be passed to a function.
attribute: A property value that is used to define signal characteristics or behavior.
base class: A class from which another class inherits attributes or properties.
basic signal component (BSC): The lowest level of building block used to define signals.
carrier language: A native computer language used to support signal and test definition (STD) signals(whether in the form of test statements or graphical representations) and to provide all other programmingrequirements.STD signals will need to be converted into carrier language code before program executioncan commence.
class: A generic set of predefined abstract test objects
component: A part of a system, which may be hardware or software and which may be subdivided intoother components. Components communicate their functionality through their interface definitions
connection: The application of a signal to a unit under test (UUT).
dynamic signal: A signal whose definition changes over time, by use of the control interface. Thesechanges must be initiated with one of the signal method calls or by changing the interconnections of asignal model.
event stream: A signal comprising a stream of active/inactive pulses generated from signal models
function: A construct that is a logically separated block of code that operates upon test values (i.e.
arguments). Another name for a function is method. Syn: method.
gated event stream: An event stream used to gate a basic signal component (BSC) or test signalframework(TSF)
Interface Definition Language (IDL): A machine-compilable language that is used to describe theinterfaces that software objects call and object implementations provide. The language provides a neutra
way to define software interfaces.
method: Syn: function.
model: A mathematical or physical representation (.e, simulation) of system relationships for a process,device,or concept.
physical: Pertaining to the natural characteristics of the universe according to the natural laws of science
procedural: The part of an signal and test definition (STD) test requirement that defines the tests in themanner and order required for testing.
property: The special form of method (or function) that supports the semantics of assignment (I-value) andreading (r-value).
reserved word: A keyword whose meaning and use are fixed by the semantics of a language. In certain otall contexts, a reserved word cannot be used for any purpose other than as defined for that language.
sensor: A transducer that converts a test parameter to a form suitable for measurement
SignalFunction: The name of the base class, for all classes that provide signals.
signal graph: See: signal model.
signal model: A collection of test signal frameworks (TSFs) or basic signal components (BSCs)interconnected to define a signal. Used to define the model part of a TSF (TSF model) or a signalcomponent used with the Require method. Syn: signal graph
static signal: A signal whose definition does not change over time. All basic signal components (BSCs)and test signal framework (TSF) models are static signals.
subclass: A class that inherits attributes or properties from a base class.
