Book excerpt: Aujourd'hui, la conception ne porte plus sur de simples objets, mais sur des systèmes complexes, sociotechniques et ouverts. Les systèmes de conduite de procédés font partie de ce type de systèmes, où les performances du système reposent sur l'optimisation conjointe des composantes humaines et techniques. Afin de limiter la détection d'erreur tardive, il devient alors important de pouvoir effectuer des tests tout au long de la conception, sans augmenter les coûts et les délais de conception. L'objectif de nos travaux est de faciliter l'intégration de techniques de vérification par simulation, dès le début de la conception, pour des systèmes de conduite de procédés de type gestion de fluide. Pour tenir compte du caractère adaptable du système et de son évolution dans un environnement dynamique, une première contribution porte sur la démarche de vérification, basée sur la formalisation et la contextualisation des propriétés à vérifier. Puis, afin de faciliter l'obtention des modèles de simulation du procédé nécessaires à la mise en œuvre des vérifications tout au long de la conception, nous proposons une approche de génération automatisée des modèles de simulation du procédé dans le langage Modelica (modélisation multi-domaine), à partir d'un schéma P&ID (représentation de l'architecture fonctionnelle du procédé) et d'une bibliothèque d'éléments (contenant les modèles de simulation des éléments). L'implémentation de cette approche dans le cadre du flot de conception automatisée de contrôle- commande d'Anaxagore permet d'apporter une preuve de concept et une preuve d'usage de nos propositions.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La conception des systèmes de contrôle-commande souffre souvent des problèmes de communication et d'interprétation des spécifications entre les différents intervenants provenant souvent de domaines techniques très variés. Afin de cadrer la conception de ces systèmes, plusieurs démarches ont été proposées dans la littérature. Parmi elles, la démarche dite mixte (ascendante/descendante), qui voit la conception réalisée en deux phases. Dans la première phase (ascendante), un modèle du système est défini à partir d'un ensemble de composants standardisés. Ce modèle subit, dans la deuxième phase (descendante), plusieurs raffinages et transformations pour obtenir des modèles plus concrets (codes,applicatifs, etc.). Afin de garantir la qualité des systèmes conçus par cette démarche, nous proposons dans cette thèse, deux approches de vérification formelle basées sur le Model-Checking. La première approche porte sur la vérification des composants standardisés et permet la vérification d'une chaîne de contrôle-commande élémentaire complète. La deuxième approche consiste en la vérification des modèles d'architecture (P&ID) utilisés pour la génération des programmes de contrôle-commande. Cette dernière est basée sur la définition d'un style architectural en Alloy pour la norme ANSI/ISA-5.1. Pour supporter les deux approches, deux flots de vérification formelle semi-automatisés basés sur les concepts de l'IDM ont été proposés. L'intégration des méthodes formelles dans un contexte industriel est facilitée, ainsi, par la génération automatique des modèles formels à partir des modèles de conception maîtrisés par les concepteurs métiers. Nos deux approches ont été validées sur un cas industriel concret concernant un système de gestion de fluide embarqué dans un navire.

Book excerpt: Integrated circuit capacity follows Moore's law, and chips are commonly produced at the time of this writing with over 70 million gates per device. Ensuring correct functional behavior of such large designs before fabrication poses an extremely challenging problem. Formal verification validates the correctness of the implementation of a design with respect to its specification through mathematical proof techniques. Formal techniques have been emerging as commercialized EDA tools in the past decade. Simulation remains a predominantly used tool to validate a design in industry. After more than 50 years of development, simulation methods have reached a degree of maturity, however, new advances continue to be developed in the area. A simulation approach for functional verification can theoretically validate all possible behaviors of a design but requires excessive computational resources. Rapidly evolving markets demand short design cycles while the increasing complexity of a design causes simulation approaches to provide less and less coverage. Formal verification is an attractive alternative since 100% coverage can be achieved; however, large designs impose unrealistic computational requirements. Combining formal verification and simulation into a single integrated circuit validation framework is an attractive alternative. This book focuses on an Integrated Design Validation (IDV) system that provides a framework for design validation and takes advantage of current technology in the areas of simulation and formal verification resulting in a practical validation engine with reasonable runtime. After surveying the basic principles of formal verification and simulation, this book describes the IDV approach to integrated circuit functional validation.

Download or read book Advanced Verification Techniques written by Leena Singh and published by Springer Science & Business Media. This book was released on 2004-06-08 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: "As chip size and complexity continues to grow exponentially, the challenges of functional verification are becoming a critical issue in the electronics industry. It is now commonly heard that logical errors missed during functional verification are the most common cause of chip re-spins, and that the costs associated with functional verification are now outweighing the costs of chip design. To cope with these challenges engineers are increasingly relying on new design and verification methodologies and languages. Transaction-based design and verification, constrained random stimulus generation, functional coverage analysis, and assertion-based verification are all techniques that advanced design and verification teams routinely use today. Engineers are also increasingly turning to design and verification models based on C/C++ and SystemC in order to build more abstract, higher performance hardware and software models and to escape the limitations of RTL HDLs. This new book, Advanced Verification Techniques, provides specific guidance for these advanced verification techniques. The book includes realistic examples and shows how SystemC and SCV can be applied to a variety of advanced design and verification tasks." - Stuart Swan

Download or read book Verification and Validation for Modeling and Simulation written by Jeffrey Strickland and published by Lulu.com. This book was released on 2014-12-08 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work began when I was appointed as a Technical Director for Modeling and Simulation (M&S) Verification and Validation (V&V) for a major defense system in 2008. It is intended to provide the nuts and bolts of performing M&S V&V in one volume. It is not intended to provide a holistic approach to M&S V&V, as that can be derived from other sources. As such, this book assumes a basic understanding of V&V, including its place in the lifecycle, its purpose and its scope for ensuring the quality of models and simulations. During the process of developing this text, the Simulation Interoperability Standards Organization (SISO) completed SISO-GUIDE-001.2-2013, Guide for Generic Methodology for Verification and Validation (GM-VV) to Support Acceptance of Models, Simulations, and Data, 2 Volumes, June 2013. The guide does serve the purpose not covered by this book. This text provides procedural details for performing V&V. The procedures are static, dynamic and informal.

Download or read book Automation of Simulation based Verification at the Register Transfer and Behavioral Levels written by Patricia Solan Lee and published by . This book was released on 2013 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even with the end of Moore's Law in sight, designs are not only becoming larger with higher complexity but more ubiquitous and numerous. Applications in the medical, environmental, consumer products, space exploration, defense, and governmental industries have seen a rise in the number of large systems for "big data" processing and small embedded systems with application-specific uses. In order to meet this growing demand for technology, the models must meet this level of complexity with higher levels of abstraction. Moving beyond register transfer and cycle accurate levels, a new paradigm of behavioral and specification level models and methodologies are being researched in hardware engineering in order to satisfy these ever-shifting needs of high functionality. The complexity of algorithms and methods to verify these systems pose an even greater challenge as design implementations grow and change. Two prominent methods of verifying a system is by using formal methods of verification and simulation-based validation. In this dissertation, I present two techniques, one that minimizes the impact of the human factor in comparing verification techniques in model checking and simulation and another that automates the creation of a testbench framework. In the first technique, I present a verification evaluation strategy for comparing model checking/equivalence checking with simulation-based verification in order to find the area of highest impact in the field. Discovering that simulation-based verification provided comparable results to that of model checking, I elected to focus my research in this area. I develop automation techniques in the verification of hardware designs written at the register transfer level [RTL] with techniques in testbench generation and response checking at the specification level. The evaluation framework utilizes standard benchmark designs with a proven method for accuracy with the use of automation in the comparison of equivalence checking and simulation-based techniques. I argue that our automated behavioral level functional verification techniques in testbench generation and response checking target specification-level errors not found within other approaches. I define and model the testbench and response checking designs automatically with the use of higher level models that preserve and utilize specification level constructs.

This book was released on 1992-01-01 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study on verification, validation, and accreditation (VV & A) seeks, for military models and simulations, to (1) provide a simple and realistic framework for modelers, analysts, managers, and recipients of analysis; (2) address important complications that have received too little attention in the past (e.g., evaluation of knowledge-based models such as those representing command-and-control decisions and other behaviors); and (3) discuss how modern model-building technology is changing the way we should develop models and conduct VV & A. The study illustrates many of its suggestions about VV & A with specific examples of language that might be used in reports and accreditation reviews. It sketches elements of advanced modeling and analysis environments that would make such work easier.
