Multi-Rate Latency insertion Method for the Fast Transient Simulation of Large Networks with Nonlinear Termination

In this paper, the authors propose a fast transient simulation technique using multirate LIM (latency insertion method). In this work, the time step size is selected according to the LC value of each part in the given network. Then, this method can reduce the calculation costs without violating the stability condition. Finally, some circuit simulations of the example networks including linear and nonlinear elements are performed by the proposed method. From the simulation results, the validity and the efficiency of this technique is verified
