Download or read book Systems Engineering Using SDL 92 written by A. Olsen and published by Newnes. This book was released on 2012-12-02 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: CCITT (now ITU-T) Specification and Description Language (SDL) and systems engineering (formal and informal) in SDL are considered in this publication. The latest version of the language, SDL-92 [ITU Z.100 SDL-92] is introduced. The book has been written for existing and potential users of SDL - technologists involved in the specification and engineering of systems. It offers easier learning, through examples and application, than the Z.100 Recommendation of March 1993, which gives precise technical definitions and concepts. The book has sufficient coverage of the language so that for normal use it should not be necessary to consult Z.100. For this reason, the grammars, both textual and graphical, are included, and the index makes it possible to find text on most of the language mechanisms. Chapter 1 provides an overview of specification and design of telecommunication systems. It considers the usage and scope of SDL. Chapter 2 gives an overview of the language, with an introduction of the major language elements. Chapter 3 focuses on the specification of behaviour and the information interchange between processes. Chapter 4 covers the structuring of systems in terms of instances, how these may be defined by types and how types may be organised in type/subtype hierarchies by inheritance. Parameterised types and packages of type definitions are also covered. Chapter 5 presents the part of the language that provides data types, with emphasis placed on how to use predefined data types. Chapter 6 presents the use of SDL for system engineering, with a discussion of general systems engineering principles followed by an introduction to methodologies which use SDL. The use of other languages in combination with SDL, documentation issues, naming and other lexical rules, errors and language support are considered, since they are more relevant to the use of language in engineering than when initially learning the language.
Download or read book Electronic Chips Systems Design Languages written by Jean Mermet and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electronic Chips & Systems Design Languagesoutlines and describes the latest advances in design languages. The challenge of System on a Chip (SOC) design requires designers to work in a multi-lingual environment which is becoming increasingly difficult to master. It is therefore crucial for them to learn, almost in real time, from the experiences of their colleagues in the use of design languages and how these languages have become more advanced to cope with system design. System designers, as well as students willing to become system designers, often do not have the time to attend all scientific events where they could learn the necessary information. This book will bring them a selected digest of the best contributions and industry strength case studies. All the levels of abstraction that are relevant, from the informal user requirements down to the implementation specifications, are addressed by different contributors. The author, together with colleague authors who provide valuable additional experience, presents examples of actual industrial world applications. Furthermore the academic concepts presented in this book provide excellent theories to student readers and the concepts described are up to date and in so doing provide most suitable root information for Ph.D. postgraduates.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the 14th SDL Forum, Bochum, Germany entitled Design for Motes and Mobiles. The SDL Forum has been held every two years for the last three decades and is one of the most important open events in the calendar for anyone from academia or industry involved in System DesignLanguagesandmodelling technologies. It is a primary conference event for discussion of the evolution and use of these languages. The most recent innovations, trends, experiences, and concerns in the ?eld are discussed and presented. The SDL Forum series addresses issues related to the modelling and analysis of reactive systems, distributed systems, and real-time and complex systems such as telecommunications, automotive, and aerospace applications. The intended audience of the series includes users of modelling techniques in industrial, research, and standardization contexts, as well as tool vendors and language researchers. Of course, during the last three decades languages, associated methods, and tools have evolved and new ones have been developed. The application domain haschangedalmostbeyondrecognition.

Download or read book The SPIN Verification System written by Jean-Charles Grégoire and published by American Mathematical Soc.. This book was released on 1997 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is SPIN? SPIN is a general tool for the specification and formal verification of software for distributed systems. It has been used to detect design errors in a wide range of applications, such as abstract distributed algorithms, data communications protocols, operating systems code, and telephone switching code. The verifier can check for basic correctness properties, such as absence of deadlock and race conditions, logical completeness, or unwarranted assumptions about the relative speeds of processes. It can also check for more subtle, system dependent correctness properties expressed inthe syntax of Linear-time Temporal Logic (LTL). The tool translates LTL formulae automatically into automata representations, which can be used in an efficient on-th-fly verifications procedure. This DIMACS volume presents the papers contributed to the second international workshop that was held on the SPIN verification system at Rutgers University in August 1996. The work covers theoretical and foundational studies of formal verifications, empirical studies of the effectiveness of different types of algorithms, significant practical applications of the SPIN verifier, and discussions of extensions and revisions of the basic code. This text will be of interest to those working in applications.
Download or read book SDL 2005 Model Driven written by Andreas Prinz and published by Springer. This book was released on 2005-06-02 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the 12th SDL Forum, Grimstad, Norway. The SDL Forum was ?rst held in 1982, and then every two years from 1985. Initially the Forum was concerned only with the Speci?cation and Description Language that was ?rst standardized in the 1976 Orange Book of the Inter- tional Telecommunication Union (ITU). Since then, many developments took place and the language has undergone several changes. However, the main underlying paradigm has survived, and it is the reason for the success of the Speci?cation and Description Language in many projects. This paradigm is based on the following important principles of distributed - plications: Communication: large systems tend to be described using smaller parts that communicate with each other; State: the systems are described on the basis of an explicit notion of state; State change: the behavior of the system is described in terms of (local) changes of the state. The original language is not the only representative for this kind of paradigm, so the scope of the SDL Forum was extended quite soon after the ?rst few events to also include other ITU standardized languages of the same family, such as MSC, ASN.1 and TTCN. This led to the current scope of System Design Languages coveringallstagesofthedevelopmentprocessincludinginparticularSDL,MSC, UML, ASN.1, eODL, TTCN, and URN. The focus is clearly on the advantages to users, and how to get from these languages the same advantage given by the ITU Speci?cation and Description Language: code generation from high-level speci?cations.

This book was released on 2006-11-22 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: A set of original results in the ?eld of high-level design of logical control devices and systems is presented in this book. These concern different aspects of such important and long-term design problems, including the following, which seem to be the main ones. First, the behavior of a device under design must be described properly, and some adequate formal language should be chosen for that. Second, effective algorithmsshouldbeusedforcheckingtheprepareddescriptionforcorrectness, foritssyntacticandsemanticveri?cationattheinitialbehaviorlevel.Third,the problem of logic circuit implementation must be solved using some concrete technological base; ef?cient methods of logic synthesis, test, and veri?cation should be developed for that. Fourth, the task of the communication between the control device and controlled objects (and maybe between different control devices)waitsforitssolution.Alltheseproblemsarehardenoughandcannotbe successfully solved without ef?cient methods and algorithms oriented toward computer implementation. Some of these are described in this book. The languages used for behavior description have been descended usually from two well-known abstract models which became classic: Petri nets and ?nite state machines (FSMs). Anyhow, more detailed versions are developed and described in the book, which enable to give more complete information concerningspeci?cqualitiesoftheregardedsystems.Forexample,themodelof parallelautomatonispresented,whichunliketheconventional?niteautomaton can be placed simultaneously into several places, calledpartial.

Available in PDF, EPUB and Kindle. Book excerpt: GATEWAYS TO DEMOCRACY continues with its framework of "gateways" to help readers conceptualize participation and civic engagement--even democracy itself--with reference to how individuals access the political system. This approach helps readers better see the relevance of government in their lives. GATEWAYS uniquely incorporates policy into a section at the end of each chapter, helping readers better understand the connection between public opinion, policy-making and how public policy applies to their lives. The second edition, complete with 2012 election updates, emphasizes critical thinking by clearly outlining learning outcomes and enhancing learning with self-assessment "Checkpoints" and a clear chapter study plan. Chapters in this ESSENTIALS version are condensed to accommodate a shorter format but preserve the integrity of the text's hallmarks.

Download or read book Systems Engineering with SDL written by Andreas Mitschele-Thiel and published by John Wiley & Sons. This book was released on 2001-02-08 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: SDL (Specification and Description Language) is a modern, high-level programming language intended for the description of complex, event-driven, real-time and communicating systems. SDL was originally designed to describe performance-critical, real-time systems with precision and accuracy, and, if used correctly, it can significantly enhance the performance of system designs. This text is unique in the integration between performance and design issues, describing the specific problems encountered when specifying, designing and implementing communication systems with SDL, and offers experience-based advice and solutions. Other topics covered include * Navigating through complex design processes * Strategies for deriving efficient implementations from SDL descriptions * The latest version of SDL, SDL-2000 Systems Engineering with SDL also includes a CD-ROM containing a demonstration version of Telelogic's SDL design suite 'Tau' - the market leading SDL design tool which further reinforces the comprehensive integration between theory and practice. Written by a former system architect at Alcatel who currently serves on the ITU standards body for SDL, responsible for the development of performance and time aspects of the standard, this valuable reference resource is principally of use to practitioners using SDL to develop communicating systems, communication protocols, distributed systems, embedded systems, especially systems architects, development engineers and tool builders making strategic design decisions. However, the comprehensive coverage and concise and practical style make this text also applicable to students on graduate level courses on protocol engineering, communication systems engineering and distributed systems.
Download or read book SDL 97 Time for Testing written by Ana Cavalli and published by Elsevier. This book was released on 1997-08-18 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Cavalli and Sarma astutely remarked in the introduction to this volume, it is quite remarkable that SDL '97 may have the first participant younger than SDL itself. SDL '97 provides the opportunity to reflect the course SDL has taken and why it has been successful over two decades where other languages addressing the same market have failed. SDL now also has a permanent companion in MSC (Message Sequence Charts). MSC today is a language in its own right and has its areas of application both in conjunction with SDL and independently or in combination with other techniques. MSC has strong structuring concepts to specify message sequences for large systems and can be used to develop scenarios, which is extremely useful for test and design environments. The SDL Forum today really is the SDL and MSC Forum.

Download or read book FM 99 Formal Methods written by Jeannette M. Wing and published by Springer Science & Business Media. This book was released on 1999-09-13 with total page 955 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formal methods are coming of age. Mathematical techniques and tools are now regarded as an important part of the development process in a wide range of industrial and governmental organisations. A transfer of technology into the mainstream of systems development is slowly, but surely, taking place. FM’99, the First World Congress on Formal Methods in the Development of Computing Systems, is a result, and a measure, of this new-found maturity. It brings an impressive array of industrial and applications-oriented papers that show how formal methods have been used to tackle real problems. These proceedings are a record of the technical symposium ofFM’99:alo- side the papers describingapplicationsofformalmethods,youwill ndtechnical reports,papers,andabstracts detailing new advances in formaltechniques,from mathematical foundations to practical tools. The World Congress is the successor to the four Formal Methods Europe Symposia, which in turn succeeded the four VDM Europe Symposia. This s- cession re?ects an increasing openness within the international community of researchers and practitioners: papers were submitted covering a wide variety of formal methods and application areas. The programmecommittee re?ects the Congress’s international nature, with a membership of 84 leading researchersfrom 38 di erent countries.The comm- tee was divided into 19 tracks, each with its own chair to oversee the reviewing process. Our collective task was a di cult one: there were 259 high-quality s- missions from 35 di erent countries.
Download or read book UML for Real written by Luciano Lavagno and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complexity of most real-time and embedded systems often exceeds that of other types of systems since, in addition to the usual spectrum of problems inherent in software, they need to deal with the complexities of the physical world. That world—as the proverbial Mr. Murphy tells us—is an unpredictable and often unfriendly place. Consequently, there is a very strong motivation to investigate and apply advanced design methods and technologies that could simplify and improve the reliability of real-time software design and implementation. As a result, from the first versions of UML issued in the mid 1990’s, designers of embedded and real-time systems have taken to UML with vigour and enthusiasm. However, the dream of a complete, model-driven design flow from specification through automated, optimised code generation, has been difficult to realise without some key improvements in UML semantics and syntax, specifically targeted to the real-time systems problem. With the enhancements in UML that have been proposed and are near standardisation with UML 2. 0, many of these improvements have been made. In the Spring of 2003, adoption of a formalised UML 2. 0 specification by the members of the Object Management Group (OMG) seems very close. It is therefore very appropriate to review the status of UML as a set of notations for embedded real-time systems - both the state of the art and best practices achieved up to this time with UML of previous generations - and where the changes embodied in the 2.
