Book excerpt: FACE AUX PROGRES ACCOMPLIS DANS LE DOMAINE DE L'INTEGRATION DES CIRCUITS INTEGRES VLSI, LES CIRCUITS ANALOGIQUES DEVIENNENT PLUS COMPLEXES ET PLUS DIFFICILES A TESTER. CETTE THESE PRESENTE UNE NOUVELLE METHODOLOGIE POUR LA SIMULATION DE FAUTES ET L'OPTIMISATION AUTOMATIQUE DES TESTS DE PRODUCTION POUR LES CIRCUITS INTEGRES ANALOGIQUES EN TENANT COMPTE DES VARIATIONS DU PROCESSUS DE FABRICATION DES CIRCUITS INTEGRES. LE SIMULATEUR DE FAUTES EST UN OUTIL INDISPENSABLE AU DEVELOPPEMENT DE TOUTE STRATEGIE DE TEST, IL PERMET DE VALIDER LES TECHNIQUES DE CONCEPTION EN VUE DU TEST (DFT), ET DE REDUIRE LES COUTS DES TESTS DE PRODUCTION. LES DEUX CARACTERISTIQUES IMPORTANTES D'UN SIMULATEUR DE FAUTES SONT : PRECISION ET RAPIDITE. POUR REPONDRE A L'EXIGENCE DE PRECISION DANS LE MONDE ANALOGIQUE OU LES VALEURS SONT IMPRECISES ET AVEC TOLERANCES, NOUS AVONS DEFINI UNE FONCTION DE PROBABILITE DE DETECTION DE FAUTES (PDF) QUI PERMET DE QUANTIFIER LE DEGRE DE DETECTION POSSIBLE D'UNE FAUTE DONNEE. POUR LA RAPIDITE, NOUS AVONS PROPOSE UN NOUVEAU ALGORITHME QUI UTILISE DES TESTS D'ARRET POUR REDUIRE LE TEMPS DE SIMULATION DE FAUTES. POUR LES CIRCUITS ANALOGIQUES, LES TESTS DEPENDENT DE LA NATURE DU CIRCUIT A TESTER. IL EST DONC IMPOSSIBLE DE DEVELOPPER UN GENERATEUR AUTOMATIQUE DE VECTEURS DE TEST POUR TOUS LES TYPES DE CIRCUITS. C'EST POURQUOI NOUS AVONS ATTAQUE LE PROBLEME DE L'OPTIMISATION AUTOMATIQUE D'ENSEMBLES DE TESTS PRE-EXISTANTS. AFIN DE TENIR COMPTE DES FLUCTUATIONS DU PROCESSUS DE FABRICATION, UNE METHODE D'OPTIMISATION DES TESTS DE PRODUCTION BASEE SUR LA FONCTION DE PROBABILITE DE DETECTION DE FAUTES A ETE PRESENTEE. UN PROTOTYPE D'OUTIL DE SIMULATION DE FAUTES ET D'OPTIMISATION AUTOMATIQUE DES TESTS DE PRODUCTION A ETE DEVELOPPE POUR VALIDER NOTRE APPROCHE. CE PROTOTYPE NOUS A PERMIS DE VALIDER, SUR PLUSIEURS CIRCUITS, NOTRE METHODE BASEE SUR LES PROBABILITES DE DETECTION DE FAUTES, ET LES RESULTATS DE PERFORMANCE OBTENUS SONT TRES ENCOURAGEANTS.

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La part dû au test dans le coût de conception et de fabrication des circuits intégrés ne cesse de croître, d'où la nécessité d'optimiser cette étape devenue incontournable. Dans cette thèse, de nouvelles méthodes d'ordonnancement et de réduction du nombre de tests à effectuer sont proposées. La solution est un ordre des tests permettant de détecter au plus tôt les circuits défectueux, qui pourra aussi être utilisé pour éliminer les tests redondants. Ces méthodes de test sont basées sur la modélisation statistique du circuit sous test. Cette modélisation inclus plusieurs modèles paramétriques et non paramétrique permettant de s'adapté à tous les types de circuit. Une fois le modèle validé, les méthodes de test proposées génèrent un grand échantillon contenant des circuits défectueux. Ces derniers permettent une meilleure estimation des métriques de test, en particulier le taux de défauts. Sur la base de cette erreur, un ordonnancement des tests est construit en maximisant la détection des circuits défectueux au plus tôt. Avec peu de tests, la méthode de sélection et d'évaluation est utilisée pour obtenir l'ordre optimal des tests. Toutefois, avec des circuits contenant un grand nombre de tests, des heuristiques comme la méthode de décomposition, les algorithmes génétiques ou les méthodes de la recherche flottante sont utilisées pour approcher la solution optimale.

Book excerpt: LES RECHERCHES PRESENTES DANS CETTE THESE CONTRIBUENT AU TEST DES CIRCUITS ANALOGIQUES OU MIXTES PAR L'ETUDE DES MODELES DE FAUTES ET PAR LA REALISATION D'OUTILS DE SIMULATION DE FAUTES. LES DEFAUTS PHYSIQUES SURVENANT LORS DE LA FABRICATION DES CIRCUITS SONT INVENTORIES. DIFFERENTS MODELES ET TECHNIQUES D'INJECTION DE FAUTES PERMETTANT DE SIMULER CES DEFAUTS DANS LES CIRCUITS ANALOGIQUES SONT ENVISAGES ET EVALUES A L'AIDE DE CIRCUITS A BASE DE TRANSISTORS MOS OU BIPOLAIRES. L'EFFET CES DEFAUTS SUR UNE CELLULE LOGIQUE EST ANALYSE ET L'ADEQUATION DE MODELES DE FAUTES LOGIQUES EXISTANTS EST ETUDIEE. DE NOUVEAUX MODELES SONT INTRODUITS ET LA CONSTRUCTION D'UN CATALOGUE DE MODELES DE FAUTES EST PROPOSEE. LES COURT-CIRCUITS INTERVENANT ENTRE LES SIGNAUX ISSUS DE DEUX CELLULES LOGIQUES SONT TRAITES PAR UNE METHODE FAISANT INTERVENIR UN SIMULATEUR MIXTE ET DES MODELES COMPORTEMENTAUX DE CELLULE LOGIQUES. CETTE ETUDE EST EGALEMENT ETENDUE AUX COURT-CIRCUITS DANS LES CIRCUITS MIXTES. DES MODELES COMPORTEMENTAUX DE SYSTEMES DE TEST ANALOGIQUE SONT REALISES ET PERMETTENT DE CONCEVOIR UN BANC DE TEST VIRTUEL AIDANT A L'ECRITURE DES VECTEURS DE TEST. DES OUTILS DE SIMULATION DE FAUTES POUR CIRCUITS ANALOGIQUES OU MIXTES SONT DEVELOPPES PERMETTANT DE MESURER LE TAUX DE COUVERTURE DE FAUTES DU TEST ET DE SELECTIONNER LES VECTEURS DE TEST.

This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les microsystemes sont des composants electromecaniques fabriques a l'echelle du micron par des procedes technologiques issus des microelectronique. Ils associent sur un meme substrat des capteurs et des actionneurs avec des circuits analogiques et numeriques d'interface. Comme pour les circuits integres, le test des microsystemes est une etape importante du cycle de fabrication en terme de cout mais egalement pour assurer un certain niveau de qualite et de fiabilite. Le but de cette these est de transposer aux microsystemes les techniques de test structurel developpees pour les circuits integres. Ces techniques sont la simulation de fautes et la conception en vue du test. La simulation de fautes permet de generer des stimuli de test visant des defauts physiques du systeme et susceptibles d'affecter le comportement du composant. Pour transposer cette technique aux microsystemes, il a fallu tout d'abord faire une etude des mecanismes de defaillance et des defauts des microsystemes. Nous avons cible deux technologies differentes et representatives des microsystemes. Une fois les defauts repertories notre etude s'est portee sur la modelisation et l'injection des fautes dans les differents niveaux de modelisation des microsystemes. La conception en vue du test est un ensemble de techniques facilitant les etapes de test de production par l'insertion d'elements specifiques dans le circuit. En ce qui concerne les microsystemes, nous avons cherche, dans cette these, a developper des elements permettant de generer des stimuli de test de differentes natures (multidisciplinaires) a partir de signaux electriques et ceci directement sur le circuit. Nous avons applique une conception auto-test a deux exemples de microsystemes, un capteur d'empreintes digitales a micropoutres et un detecteur infrarouge a thermopiles. Dans les deux cas les elements rajoutes permettent d'effectuer un test structurel sans avoir recours a une source externe.

Book excerpt: LE DEVELOPPEMENT DES TECHNOLOGIES DE FABRICATION ET DES OUTILS DE CONCEPTION DE CIRCUITS INTEGRES A PERMIS LA MISE EN OEUVRE D'APPLICATIONS NOUVELLES UTILISANT DES SIGNAUX-MIXTES ANALOGIQUES/NUMERIQUES, ET L'APTITUDE A INTEGRER DES SYSTEMES ANALOGIQUES ET MIXTES COMPLEXES DANS LA MEME PUCE CROIT RAPIDEMENT. DONC, LE TEST DE CES CIRCUITS NECESSITE UNE GRANDE ATTENTION, PARTICULIEREMENT SUR LE COUT DU TEST EN PRODUCTION QUI EST UN FACTEUR PROEMINENT DANS LE COUT TOTAL. EN OUTRE, LE TEST DES CIRCUITS INTEGRES ANALOGIQUES ET MIXTES EST UNE TACHE TRES DIFFICILE QUI EST DEVENUE UN DOMAINE DE RECHERCHE TRES INTERESSANT DANS LES DERNIERES ANNEES. LE BUT PRINCIPAL DE CETTE THESE EST PORTE SUR LE DEVELOPPEMENT DE DEUX TECHNIQUES NOUVELLES D'AUTO-TEST INTEGRE (BIST) POUR LE TEST DES PARTIES ANALOGIQUES INTEGREES DANS LES CIRCUITS MIXTES, QUI FACILITENT LA GENERATION DU SIGNAL DE TEST ET L'OBSERVATION DU SIGNAL DE SORTIE, AUGMENTENT LA QUALITE ET LA FIABILITE DES CIRCUITS, ET REDUISENT LE COUT DE TEST. LE PREMIER OBJECTIF EST D'AMELIORER LE PROBLEME DE GENERATION DU SIGNAL DE TEST, QUI EST ACCOMPLI EN CONSIDERANT DES COURANTS COMME DES SIGNAUX DE TEST. EN UTILISANT CETTE APPROCHE, NOUS REPONDONS AUX EXIGENCES SUIVANTES : A) UNE GRANDE CONTROLABILITE DE L'APPLICATION DES SIGNAUX DE TEST, CAR ILS PEUVENT ETRE APPLIQUES INDIVIDUELLEMENT OU SIMULTANEMENT, B) L'APPLICATION DE TELS SIGNAUX DE TEST NE REQUIERT PLUS L'UTILISATION DE COMMUTATEURS, CE QUI DIMINUE LES DEGRADATIONS DES PERFORMANCES INTRODUITES PAR LE CIRCUIT DE TEST, ET C) UNE GRANDE OBSERVABILITE DE LA REPONSE DE TEST EST ACCOMPLIE, CE QUI MINIMISE LA PROBABILITE DE DECISION ERRONEE DE TEST, MAXIMISE LE TAUX DE COUVERTURE DE DEFAUTS, ET REDUIT LE TEMPS ET LE COUT DE TEST. LE DEUXIEME OBJECTIF POURSUIT L'OPTIMISATION DU PROBLEME DE LA MESURE DE LA REPONSE DE TEST, CE QUI EST ABORDE PAR L'UTILISATION DES CIRCUITS DE TRAITEMENT DE COURANT AFIN D'ANALYSER LA REPONSE DE TEST. CELA REPRESENTE CERTAINS AVANTAGES CONSIDERABLES PAR RAPPORT AUX TECHNIQUES CLASSIQUES. EN OUTRE, L'IMPACT DU CIRCUIT DE TEST SUR LES PERFORMANCES DU CIRCUIT TESTE EST NEGLIGEABLE. LE TROISIEME OBJECTIF VISE L'AUGMENTATION DE L'OBSERVABILITE DES BLOCS ANALOGIQUES DANS LES CIRCUITS MIXTES, CE QUI A ETE ACCOMPLI EN UTILISANT DES SIGNAUX AC/DC DE TEST A PARTIR DE DETECTEURS INTEGRES. LES SIGNAUX AC DE TEST PERMETTENT LA DETECTION DES ERREURS PENDANT L'OPERATION DES AMPLIFICATEURS OPERATIONNELS HAUTE-FREQUENCE. LES SIGNAUX DC DE TEST PERMETTENT DE DETECTER LES FAUTES QUI SONT DIFFICILES A DETECTER LORSQU'ON UTILISE LES SIGNAUX DE TEST SINUSOIDAUX DE TENSION. ENFIN, NOUS PROPOSONS L'INTEGRATION DES TECHNIQUES NOUVELLES DE BIST DANS UN ENVIRONNEMENT DE CAO, EN UTILISANT LES LANGAGES HAUT-NIVEAU DE DESCRIPTION COMPORTEMENTALE ANALOGIQUE.

Book excerpt: Connected objects today present a range of opportunities in medicine. We live in a new digital era where the monitoring and analysis of one's own health information no longer belongs solely to the realm of science fiction. The success of these new devices resides in their usage, which integrates seamlessly into the daily life of the user in order to continually collect the maximum amount of data. These medical connected devices therefore constitute a new hope in transforming user experience as well as the care pathway. They offer a better level of support and a better quality of life for those suffering from chronic illnesses or mental, sensorial or physical disabilities. However, these solutions also pose systematic problems, especially regarding the risks linked to their usage. This book presents a cartography which clearly details all the potential risk scenarios linked to the usage of connected devices as well as the actions which should be undertaken to promote balanced governance and guarantee the development of high-quality medical devices. - Aims to help the reader understand the difference between a connected object and a medical connected device - Identifies and evaluates all the potential risks and perspectives associated with the use of connected medical devices - Shows how to make a comprehensive risk analysis with standards like ISO 31000 and 14971

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Human-Computer Interaction aims to sensitize the systems designer to the problems faced by the user of an interactive system. The book grew out of a course entitled ""The User Interface: Human Factors for Computer-based Systems"" which has been run annually at the University of York since 1981. This course has been attended primarily by systems managers from the computer industry. The book is organized into three parts. Part One focuses on the user as processor of information with studies on visual perception; extracting information from printed and electronically presented text; and human memory. Part Two on the use of behavioral data includes studies on how and when to collect behavioral data; and statistical evaluation of behavioral data. Part Three deals with user interfaces. The chapters in this section cover topics such as work station design, user interface design, and speech communication. It is hoped that this book will be read by systems engineers and managers concerned with the design of interactive systems as well as graduate and undergraduate computer science students. The book is also suitable as a tutorial text for certain courses for students of Psychology and Ergonomics.

This book was released on 2011-12-15 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.

Download or read book Energy Management in Wireless Sensor Networks written by Youcef Touati and published by ISTE Press - Elsevier. This book was released on 2017-03-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy Management in Wireless Sensor Networks discusses this unavoidable issue in the application of Wireless Sensor Networks (WSN). To guarantee efficiency and durability in a network, the science must go beyond hardware solutions and seek alternative software solutions that allow for better data control from the source to delivery. Data transfer must obey different routing protocols, depending on the application type and network architecture. The correct protocol should allow for fluid information flow, as well as optimizing power consumption and resources - a challenge faced by dense networks. The topics covered in this book provide answers to these needs by introducing and exploring computer-based tools and protocol strategies for low power consumption and the implementation of routing mechanisms which include several levels of intervention, ranging from deployment to network operation.

Download or read book Acoustic Emission and Durability of Composite Materials written by Nathalie Godin and published by John Wiley & Sons. This book was released on 2018-05-08 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, two kinds of analysis based on acoustic emission recorded during mechanical tests are investigated. In the first, individual, analysis, acoustic signature of each damage mechanism is characterized. So with a clustering method, AE signals that have similar shapes or similar features can be group together into a cluster. Afterwards, each cluster can be linked with a main damage. The second analysis is based on a global AE analysis, on the investigation of liberated energy, with a view to identify a critical point. So beyond this characteristic point, the criticality can be modeled with a power-law in order to evaluate time to failure.
