3、ools can express and communicate the observable features of system/software behavior to users and to other tools is presented. This standard specifies a Conceptual Metamodel for understanding and describing the causal behavior for a system. The purpose of this Conceptual Metamodel is to express caus
4、al behavior and compositions of causal behavior in a model that integrates all observable operational features of a system into one behavior specification. This Conceptual Metamodel is useful for analyzing systems, for constructing particular system behavior models, and for using those models in the
5、 specification, design, and evaluation of engineered systems. It provides the necessary semantic elements for describing general hardware/software systems, including hardware-only, software-only, or mixed system components, and it allows these different types of components to be treated in a consist
6、ent manner, providing a basis for representing a wide variety of systems.

15、ards.jsp. This family of standards replaces IEEE Std 1175-1991 B3.b IEEE Std 1175-1991 was advanced to a full-use standard in 1994. It covered a number of closely related subjects, and the scope of material contained was able to serve a number of divergent interests. This family of standards restruc
16、tures and substantially augments the material in IEEE Std 1175-1991. It has been divided into several individually useful documents in order to facilitate its use by different communities of interest. These guides, recommended practices, and standards generally address issues involved in characteriz
17、ing the kinds of interconnections that exist between a computing system tool and its environment. Although particularly intended to address the implementation and use of Computer-Aided Software Engineering (CASE) tools, the discussion of interconnections in this family actually has wider applicabili
18、ty to computing system tools in general, beyond only CASE tools. aNotes in text, tables, and figures of a standard are given for information only and do not contain requirements needed to implement this standard. bAlthough approved in 1991, IEEE Std 1175-1991 was actually published in 1992 and is so
19、metimes found referenced as IEEE Std 1175-1992. It appears in the standards numerical listing on the IEEE Xplore Web site (http:/ieeexplore.ieee.org/) as IEEE Std 1175-1992, with the title IEEE Trial-Use Standard Reference Model for Computing System Tool Interconnections. In 1994, the term trial-use
20、 was removed from the title when the standard was approved for full-use status. The 1994 version, which was identical to the 1992 publication except for the title and minor editorial corrections, is not available on the IEEE Web site. v Copyright 2009 IEEE. All rights reserved. Four kinds of interco
21、nnections with a computing system tool are addressed: interconnections with organizations, users, platforms, and other computing system tools. Consideration of interconnections is important to understanding, selecting, implementing, and using computing system tools. Also, although many computing sys
22、tem tools do not need to communicate behavior descriptions of subject systems, their creators need to develop such behavior descriptions for the tools themselves. A brief summary overview of each of the members of this family of standards is given in the following paragraphs. A more complete overvie
23、w is available in IEEE Std 1175.1-2002 B4, which provides an integrated overview of the members of the 1175 family of standards, and it describes the fundamental concepts that provide a basis for organizing the material. IEEE Std 1175.1-2002, IEEE Guide for CASE Tool InterconnectionsClassification a
24、nd Description IEEE Std 1175.1-2002 B4 is a guide to the IEEE 1175 family of standards. It describes how these standards are intended to be used to accomplish the effective integration of computing system tools into a productive engineering environment and sets forth the fundamental concepts on whic
25、h these standards are based. These concepts establish the integrating framework for the other members of this family of standards. IEEE Std 1175.1-2002 describes the scope of application of each member standard, the various issues addressed in each standard, and the interrelationships among the memb
26、ers of the 1175 family of standards. IEEE Std 1175.2-2006, IEEE Recommended Practice for CASE Tool InterconnectionCharacterization of Interconnections The IEEE Std 1175.2-2006 B5 recommended practice presents four contexts for a computing system tools interconnections that offer insight into the ope
27、rational problems of interconnecting computing system tools with their environment. This recommended practice establishes recommended collections of standard contextual attributes describing relationships between a computing system tool and its organizational deployment, its human user, its executab
28、le platform, and its peer tools, as illustrated in Figure a. These contextual attributes are of the “news-story” form that includes: who, what, when, where, and why. The values of these contextual attributes are references to organizational, industrial, and professional standards. By assisting users
29、 to reach a clear understanding of the context of operation for a computing system tool, this recommended practice contributes to the effective implementation and application of computing system tools.

30、oftware Behavior IEEE Std 1175.3-2004 B6 is an expansion of Part 3 of IEEE Std 1175-1991. It focuses specifically on a common set of modeling concepts found in commercial CASE tools for describing the operational behavior of a software product, and it provides a formal, logical model for describing
31、this behavior. IEEE Std 1175.3-2004 also defines a Semantic Transfer Language (STL) for communicating software behavior descriptions from one tool to another. A notable feature of the STL is its design for human readability, which makes STL text files suitable for use in software design reviews by u
32、sers unfamiliar with computing system tool diagramming notations. In addition, the design of the STL syntax readily permits analysts to prepare and edit STL descriptions using a text editor or word processor. To permit backward compatibility with Part 3 of IEEE Std 1175-1991, IEEE Std 1175.3-2004 ma

However, some aspects of the 1991 syntax that were previously left as user-defined have now been specified in order to increase the con
34、sistency and reliability with which the STL may be used for exchanging software specification information. In addition, improvements have been made in how the STL syntax is defined and explained. Finally, the STL Interconnection Profile has been replaced with more straightforward, “user-friendly” ta
35、bular and comma-separated-value formats to define a Tool Interconnection Profile that can serve the same purpose as the original form of the profile.

36、System Behavior IEEE Std 1175.4-2008 encompasses the description of the types of the computing systems supported by IEEE Std 1175.3-2004 B6, but it goes further, providing a basis for representing a wider variety of systems. Specifically, IEEE Std 1175.4-2008 provides the necessary semantic elements
37、 for describing general hardware/software systems, including hardware-only, software-only, or mixed system components, and it allows these different types of components to be treated in a consistent manner.

38、ionsReference Data Metamodel for System Behavior Specifications This standard defines a Data Metamodel for system behavior specifications. Figure b illustrates one use for such a behavior specification metamodel in the context of supporting information transfer from one users tool to another users t
39、ool. The Data Metamodel provides explicit definitions of typed data elements, information representations, and relationships with which behavior models for subject systems can be instantiated. These elements, representations, and relations serve to reify the Conceptual Metamodel for system behavior
