Abstract
The increasing complexity of circuit design needs to be managed with appropriate optimization algorithms and accurate statistical descriptions of design models in order to reach the design specifics, thus guaranteeing “zero defects”. In theDesign for Yieldopen problems are the design of effective optimization algorithms and statistical analysis for yield design, which require time consuming techniques. New methods have to balance accuracy, robustness and computational effort. Typical analog integrated circuit optimization problems are computationally hard and require the handling ofmultiple, conflicting, and non-commensurate objectives having strong nonlinear interdependence. This paper tackles the problem by evolutionary algorithms to produce tradeoff solutions. In this research work, Integrated Circuit (IC) design has been formulated as a constrained multi-objective optimization problem defined in a mixed integer/ discrete/continuous domain. TheRF Low Noise Amplifier, Leapfrog Filter, and Ultra Wideband LNA real-life circuits were selected as test beds. The proposed algorithm, A-NSGAII, was shown to produce acceptable and robust solutions in the tested applications, where state-ofart algorithms and circuit designers failed. The results show significant improvement in all the chosen IC design problems.
