Methods and apparatus for designing electronic circuits, including analog and mixed signal (AMS) circuits, based on an evolutionary optimization approach. In one exemplary embodiment, the optimization approach is implemented using a computer program running on one or more computers. The optimization program receives inputs from the designer regarding (i) optimization objectives for the design process, and (ii) the constraint mechanisms to be applied. Both constrained and unconstrained optimization formulations can be addressed by the program. Various objective function evaluation mechanisms are implemented. The program also advantageously allows for continuously encoded variables, which are particularly useful for solving AMS design problems.

L'invention concerne des procédés et un dispositif pour la conception de circuits électroniques, y compris circuits analogiques et à signaux mixtes (AMS), reposant sur une technique d'optimisation évolutive. Dans une forme de réalisation exemplaire, la technique d'optimisation est mise en oeuvre au moyen d'un programme informatique exécuté sur un ou plusieurs ordinateurs. Le programme d'optimisation reçoit des entrées provenant du concepteur relatives (1) aux objectifs d'optimisation du procédé de conception, et (2) aux systèmes de contraintes à appliquer. Le programme peut traiter des formulations d'optimisation avec ou sans contraintes. Divers systèmes d'évaluation de fonction d'objectif sont mis en oeuvre. De plus, le programme accepte avantageusement les variables codées en continu, qui sont particulièrement utiles pour résoudre des problèmes de conception de circuits AMS.
