Les langages de description de matériel constituent l'interface entre ces outils et les utilisateurs. Parmi ceux-ci, il existe un standard qui est VHDL, destiné à la description de systèmes numériques. Actuellement une extension analogique est en cours de normalisation. Les deux premiers chapitres de cette thèse sont consacrés l'un aux langages de description de matériel et à une présentation de VHDL, ainsi que des remarques et analyses à propos de son extension analogique. Le second thème de cette thèse est la mise en évidence de l'importance de la simulation en mode mixte numérique-analogique. Le troisième chapitre présente les principes généraux de la simulation mixte; différentes implémentations de simulateurs mixtes sont présentés. Enfin, le dernier chapitre est consacré à la réalisation d'un simulateur mixte dont la partie numérique est un simulateur VHDL. Cette réalisation repose sur une approche de description qui permet d'utiliser la souplesse de description structurelle de VHDL pour des systèmes analogiques et mixtes

Available in PDF, EPUB and Kindle. Book excerpt: De nos jours, l’introduction des procédés de fabrication de la technologie CMOS standard dans la réalisation de capteurs d’images, permet d’intégrer, sur une même puce (SOC) toutes les fonctionnalités requises pour l’acquisition d’une information sous forme d’images. La réalisation de ces systèmes, de plus en plus complexe, est inéluctablement, précédée d’une étape de simulation et de validation préliminaires. L’objectif de cette thèse est d’explorer la possibilité de modélisation et de simulation de capteurs d’images CMOS, en utilisant le langage de description matériel VHDL–AMS. Deux capteurs ont été modélisés et simulés. Le premier est un imageur CMOS composé d’une matrice de pixels actifs, d’un convertisseur analogique numérique et d’un séquenceur numérique. Le deuxième est un pixel passif associé à un circuit d’intégration. A travers cette étude, une méthodologie de modélisation et de simulation de capteurs d’images mixtes et multi-domaines est proposée. Cette méthode permet de prédire le comportement de tels circuits avant de procéder à leur réalisation ce qui réduit avantageusement leur coût de fabrication et leur temps de mise sur le marché.

Available in PDF, EPUB and Kindle. Book excerpt: LA CONCEPTION DE SYSTEME PASSE PAR LA DESCRIPTION COMPORTEMENTALE DES DIFFERENTES PARTIES (SOUS-SYSTEMES) DU SYSTEME ET DE LEURS INTERCOMMUNICATIONS. LE LANGAGE VHDL-AMS, DONT LA NORME EST EN TRAIN DE SORTIR, VIENT A POINT POUR FAVORISER CETTE DESCRIPTION ET CES ECHANGES. LE MEMOIRE DE THESE A POUR OBJECTIF : 1. DE PRESENTER LE PASSAGE DE LA SIMULATION ANALOGIQUE CLASSIQUE A LA SIMULATION COMPORTEMENTALE ET DE SAVOIR COMMENT TRANSFORMER UN SIMULATEUR ELECTRIQUE (SPICE) EN SIMULATEUR COMPORTEMENTAL. 2. DE MONTRER PAR DES APPLICATIONS AVEC SPICE DANS LE DOMAINE MECATRONIQUE ET PAR EXTENSION MULTI-TECHNOLOGIQUE, CE QUE PEUT APPORTER LE LANGAGE VHDL-AMS. LE MEMOIRE COMPREND DONC DEUX GRANDES PARTIES. DANS LA PREMIERE PARTIE SIMULATION ANALOGIQUE ET COMPORTEMENTALE, NOUS AVONS ETUDIE LE FONCTIONNEMENT ET LA STRUCTURE D'UN SIMULATEUR ELECTRIQUE ANALOGIQUE (SPICE), ET LES GRANDS PRINCIPES (ANALOGIQUES) DU LANGAGE VHDL-AMS EN VUE D'ELABORER UN MODULE TRADUCTEUR-INTERFACE VHDL-AMS/SPICE. LE MODULE, APPELE BVHDLA PERMET DONC A SPICE DE RECONNAITRE DES MODELES ECRITS EN VHDL-AMS ANALOGIQUE. BVHDLA EST EN FAIT PLUS QU'UN SIMPLE COMPILATEUR, CAR IL FOURNIT DE NOUVELLES DONNEES REQUISES PAR SPICE. PAR EXEMPLE IL CONTIENT UN DERIVATEUR SYMBOLIQUE, TRANSPARENT A L'UTILISATEUR, PERMETTANT LE CALCUL AUTOMATIQUE DES CONDUCTANCES ET DES TRANSCONDUCTANCES INDISPENSABLE POUR SPICE. LA SECONDE PARTIE MECATRONIQUE ET MULTI-TECHNOLOGIE, PRESENTE TOUT D'ABORD L'AVANTAGE QUE LA MISE EN PRATIQUE DE L'ANALOGIE PERMET DE TIRER ENTRE LA MECANIQUE ET L'ELECTRICITE/L'ELECTRONIQUE (LA MECATRONIQUE) : AVANTAGE DE POUVOIR UTILISER UN SIMULATEUR ELECTRIQUE POUR RESOUDRE DES PROBLEMES DE MECANIQUE. CECI N'EST CERTES PAS NOUVEAU, MAIS L'ETABLISSEMENT DE L'ANALOGIE AVEC D'AUTRES DOMAINES TECHNOLOGIQUES (THERMIQUE, RADIATIF,) PERMET D'ETENDRE LA NOTION DE MECATRONIQUE A CELLE DE MULTI-TECHNOLOGIE. NOUS MONTRONS ALORS QUE LE LANGAGE VHDL-AMS ARRIVE A POINT. POUR CELA NOUS PRESENTERONS DES APPLICATIONS RENDUES POSSIBLES GRACE A NOTRE OUTIL DE SIMULATION. EN PLUS DES APPLICATIONS S'APPUYANT SUR DES MODELES MULTI-TECHNOLOGIQUES, NOUS PRESENTERONS DES MODELES PUREMENT FONCTIONNELS, ET DES MODELES PHYSIQUES DE TYPE COMPOSANT. CECI EN VUE DE MONTRER CE QUE POTENTIELLEMENT ON PEUT ATTENDRE DE VHDL-AMS.

Available in PDF, EPUB and Kindle. Book excerpt: CETTE THESE PROPOSE UNE METHODOLOGIE DE CONCEPTION POUR LES CIRCUITS SPECIFIQUES ASIC MIXTES COMPLEXES. APRES UNE REVUE DES AVANCEES REALISEES DANS LE DOMAINE DE LA CONCEPTION D'ASIC MIXTES, UNE TECHNIQUE DE CONCEPTION EST PROPOSEE. ELLE EST BASEE SUR L'UTILISATION D'UN CO-SIMULATEUR ANALOGIQUE/NUMERIQUE ET DE LA MACROMODELISATION SPICE. DANS UN PREMIER TEMPS, NOUS PRESENTONS LA TECHNIQUE DE MACROMODELISATION SPICE PERMETTANT D'AMELIORER CONSIDERABLEMENT LES PERFORMANCES DE VITESSE ET DE PRECISION DE LA SIMULATION ELECTRIQUE. CETTE TECHNIQUE NE DEMANDE PAS UN TEMPS DE MODELISATION IMPORTANT ET PERMET DE CREER DES MODELES APTES A LA CO-SIMULATION. DANS UN DEUXIEME TEMPS, LES MACROMODELES SPICE SONT UTILISES POUR LA VERIFICATION D'UN ASIC MIXTE COMPLEXE PENDANT TOUTES LES PHASES DE LA CONCEPTION. EN EFFET, LE CO-SIMULATEUR PERMETTANT D'ANALYSER DES CIRCUITS NUMERIQUES DECRITS EN LANGAGE VHDL ET DES PARTIES ANALOGIQUES EN LANGAGE SPICE, IL EST POSSIBLE D'ELIMINER LES DEFAUTS DE FONCTIONNEMENT D'UN CIRCUIT AVANT DE LE PRODUIRE. DE PLUS, COMPTE TENU DES AMELIORATIONS INTRODUITES PAR LA MACROMODELISATION SPICE, LA VITESSE DE LA SIMULATION EST ADAPTEE AUX SYSTEMES DE GRANDE COMPLEXITE ET PAR LA, LE TEMPS DE CONCEPTION N'EST PAS DEGRADE DE MANIERE IMPORTANTE. LES VALIDATIONS REALISEES ONT ETE BASEES SUR DIVERSES IMPLANTATIONS D'ASIC DEDIES AU SYSTEME DE TELECOMMUNICATION DECT. DANS CE MANUSCRIT, NOUS PRESENTONS LES MESURES EFFECTUEES SUR DEUX DE CES ASIC POUR METTRE EN EVIDENCE LA PRECISION DE LA METHODE DE VERIFICATION. L'APPROCHE DEVELOPPEE PERMET AINSI DE REDUIRE CONSIDERABLEMENT LES COUTS ASSOCIES A LA CONCEPTION D'ASIC MIXTES : D'UNE PART LA MODELISATION ET LA SIMULATION RAPIDE DE SYSTEMES COMPLEXES REDUIT LE TEMPS DE DEVELOPPEMENT, ET D'AUTRE PART LA PRECISION DE LA TECHNIQUE EVITE LA FABRICATION DE PROTOTYPES, CAR IL EST POSSIBLE DE CORRIGER TOUS LES DEFAUTS DU CIRCUIT PENDANT LES DIVERSES PHASES DE SIMULATION.

Available in PDF, EPUB and Kindle. Book excerpt: LA DEMARCHE HIERARCHIQUE DESCENDANTE (TOP-DOWN) A REVOLUTIONNE LA METHODOLOGIE DE CONCEPTION DE CIRCUITS D'ASIC NUMERIQUES. LA NOUVELLE NORME VHDL-AMS, RECEMMENT ADOPTEE, DEVRAIT PERMETTRE L'EXTENSION DE CE MEME CONCEPT AUX CIRCUITS ANALOGIQUES ET MIXTES. CEPENDANT, L'ABSENCE DE L'OUTIL DE SYNTHESE ANALOGIQUE NE PERMET PAS UNE IMITATION EXACTE DE LA CONCEPTION DES CIRCUITS NUMERIQUES. DANS LE DOMAINE ANALOGIQUE, LE NIVEAU TRANSISTOR PREDOMINE LA PHASE DE CONCEPTION. DESORMAIS CES BLOCS DE CIRCUITS PEUVENT ETRE AUSSI REPRESENTES PAR DES MODELES COMPORTEMENTAUX. C'EST UNE DEMARCHE ASCENDANTE (BOTTOM-UP). L'ELEVATION DE NIVEAU D'ABSTRACTION DES BLOCS ANALOGIQUES APPORTE UN GAIN RADICAL EN TEMPS DE SIMULATION. LA COMBINAISON DES DEMARCHES TOP-DOWN ET BOTTOM-UP OUVRE LA PORTE A LA CONCEPTION DE SYSTEME MIXTE. DESORMAIS IL EST POSSIBLE DE REPRESENTER TOUT BLOC ANALOGIQUE ET NUMERIQUE A DES NIVEAUX D'ABSTRACTION DIFFERENTS ET DANS UN ENVIRONNEMENT DE SIMULATION UNIFIE. LE CONCEPTEUR PEUT, SELON DES OBJECTIFS DE CONCEPTION OU DE VERIFICATION RECHERCHES, CHOISIR LES COMBINAISONS DES NIVEAUX D'ABSTRACTION POUR UN COMPROMIS OPTIMAL ENTRE LA PRECISION ET LE TEMPS DE CPU. LA SIMULATION DU SYSTEME MIXTE COMPLET AU NIVEAU TOP EST DESORMAIS UNE REALITE.

Available in PDF, EPUB and Kindle. Book excerpt: At the age of twenty-eight, Marty Ellis is still a bachelor who graduated with a major in journalism and a minor in photojournalism. He enjoys his life with various girlfriends while knocking back drinks in bars, going out to dinner, and rolling in the sheets. Yet inevitably, he grows tired of these surface-level-only feelings, shells out his standard goodbye speech, and moves on. However, using only his body and saying sayonara to his love lifeaEUR(tm)s revolving door is not how he wants to live for the rest of his life. How will he ever know what true love feels like if he doesnaEUR(tm)t ascertain how to actually give it? In what way will he begin to be able to discover the whole package that runs beneath the surface of a woman? Unexpectedly, Marty is blindsided when his best friend invites him to leave New Jersey for a weekend trip. Lauren Morris is a beautiful thirty-two-year-old woman who, after graduating at the age of twenty-one with a masteraEUR(tm)s degree in business, took a huge leap of faith and purchased an old farmhouse in Vermont. After ten years of hard work and sweat equity, she has transformed it into a beautiful inn that has become extremely lucrative. But winter is fast approaching, and she is dreading that feeling of loneliness that is connected to darkened afternoons and long, empty nights. Will a man ever enter her life? One that she could love and perhaps be with until death due them part? After meeting Marty, Lauren begins to consider if this man might be the one she has been waiting for her whole life. But then again, she is older than he is; long distance relationships hardly ever work out; and sudden heartbreaking unforeseen events rock both of their worlds. And if they do fall in love, which one of them will have to make the ultimate sacrifice and give up what theyaEUR(tm)ve worked so hard to achieve in order to be together? With so many changes causing so many challenges, will they get through them together, or will one push the other away?

Download or read book Inconsistency Robustness written by Carl Hewitt and published by . This book was released on 2015-05-20 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inconsistency robustness is information system performance in the face of continually pervasive inconsistencies---a shift from the previously dominant paradigms of inconsistency denial and inconsistency elimination attempting to sweep them under the rug. Inconsistency robustness is a both an observed phenomenon and a desired feature: Inconsistency Robustness is an observed phenomenon because large information-systems are required to operate in an environment of pervasive inconsistency. Inconsistency Robustness is a desired feature because we need to improve the performance of large information system. This volume has revised versions of refereed articles and panel summaries from the first two International Symposia on Inconsistency Robustness conducted under the auspices of the International Society for Inconsistency Robustness (iRobust http: //irobust.org). The articles are broadly based on theory and practice, addressing fundamental issues in inconsistency robustness. The field of Inconsistency Robustness aims to provide practical rigorous foundations for computer information systems dealing with pervasively inconsistent information."
