ASYMPTOTIC WAVE-FORM EVALUATION FOR TRANSIENT ANALYSIS OF 3-D INTERCONNECT STRUCTURES

This paper describes a new approach to time response computation of an arbitrary 3-D interconnect structure. This technique is based on Asymptotic Waveform Evaluation (AWE) and has been implemented in a software tool called 3DAWE. To facilitate the application of AWE to a 3-D RC mesh network model, the AWE formulation is rederived based upon a nodal analysis approach. The ICCG matrix solver has been successfully applied in 3DAWE. It is shown that a typical transient response of a reasonably large 3-D RC network can be obtained within a few minutes on a 15 MIPS computer by using this program.
