To solve the re-design problem caused by manually choosing the number of decoupling capacitors,an automatic selection method based on adapted genetic algorithms for selecting the number of decoupling capacitors is proposed.This method mimics the process of natural selection presented by Darwin.By this method the scheme of using the smallest number of decoupling capacitors is selected and at the same time the target impedance constraint is satisfied so that the automatic selection can be achieved.A comparison between the simulation results and the result given by a full-wave simulation software for PCB demonstrates that this method can meet the requirement of engineering and has been adopted by a large IT company recently.
