This paper presents a modular approach to the high-frequency simulation of large networks. By utilizing the latency insertion method (LIM) and by studying the stability criteria of partitions of different latencies in the circuit, a robust method is formulated that is able to perform transient simulations significantly faster than the conventional LIM method. The LIM method is also extended to handle dependent sources, and a general stability criterion for selecting the time step, independent of the topology of the circuit, is proposed. The new method is verified with existing commercial tools for circuit simulations, and the improvement in run time is also depicted.
