Synthèse de composants analogiques intégrès VLSI réutilisables

Les concepteurs des circuits intégrés VLSI ont inventé des méthodes permettant d'exploiter la complexité croissante des circuits intégrés à haute densité d'intégration. L'une d'elles consiste à concevoir des systèmes embarqués sur puce (SoC) à l'aide de blocs pré-existants et déjà validés (appelés IP, comme Intellectual Property), qu'ils aient été élaborés en interne à l'entreprise réalisant le SoC ou issus d'une tierce partie. S'il existe un flot descendant bien établi pour concevoir les blocs intégrés numériques, la conception de circuits analogiques reste toujours une opération sur mesure. Dans cette thèse, nous proposons une méthode pour automatiser le dimensionnement et la polarisation d'un circuit analogique dans le cas général, conduisant ainsi à une définition possible d'un IP analogique. Cette méthode permet de générer automatiquement une procédure pour calculer les dimensions d'une topologie électrique connue et son point de fonctionnement en se fondant sur l'expression de la connaissance du concepteur.
