Applications of complex frequency hopping method in PCB signal integrity simulation

This paper presents a fast Signal Integrity(SI) simulator using a newly published moment matching technique, Complex Frequency Hopping(CFH), which can efficiently simulate boards containing a large number of interconnects with lossy parameters. For the first level examination of an entire board, this simulator provides an excellent solution to delay, reflection, and cross-talk by using linear component models. For the detailed analysis of an interconnection network with non-linear components, this simulator creates equivalent time domain macro-models to replace the linear subnetwork containing lossy interconnects. Such models can be easily used in any SPICE like simulator to efficiently perform accurate time domain analysis of the network.
