“…Over the past years, advances in optimization techniques and design methodologies based on interactive computing have been made (see for instance [3][4][5][6][7][8][9][10][11][12]). However these methodologies place the algorithm control in the hands of the user and hence, may pose problems.…”

We present a novel heuristic for optimizing analog circuit performances. It deals with generating the Pareto front using the topological properties of the feasible solution space. This heuristic allows us generating optimal values of circuit parameters in reduced computation time and memory consumption. Unlike basic metaheuristics, it does not need optimization background from the user in order to be easily adapted to different applications. It can thus be smoothly integrated into an automated design flow. This novel approach enables us to further improve (good) performances that were already reached using other optimizing techniques. Robustness of the algorithm was proved using specific difficult test problems.
