| Abstract: | A new dynamic IR drop analysis method based on global annealing genetic algorithm was presented.This method takes the father-generation into competition,and optimizes the fitness function with annealing,which could optimize vectors and accelerate the speed of analysis.The experimental results show that this method improves the accuracy of IR drop analysis,and accelerates the covergence rate,the reproduction algebra is reduced 35% on average,and the results is increased 10%. |
