1 Introduction The rapid development of large-scale integrated systems (VLSI) puts great demands on the speed and stability of circuit simulation. It is an important research topic to study new circuit simulation algorithms. The traditional time matching method can not effectively deal with the frequent High-speed circuits appear singularity, and the uniform approximation ability is poor, and the shortcoming of the frequency matching method is that it can not be processed in real time to control the circuit simulation accuracy.Recently, the rapid wavelet configuration algorithm can not only overcome the shortcomings of the above two methods, and The convergence rate of the calculation can reach O (h ~ 4) (the general solution of the equation can only reach O (h ~ 2)), h is the step.
