Asymptotic waveform evaluation for transient analysis of 3-D interconnect structures

An approach to computing the time response of an arbitrary 3-D interconnect structure based on asymptotic waveform evaluation (AWE) is introduced. It has been implemented in a software tool called 3DAWE. To facilitate the application of AWE to a 3D RC mesh network model, the AWE formulation is rederived based on a nodal analysis approach. The ICCG matrix solver has been successfully applied in 3DAWE. It is shown that the typical transient response of a reasonably large 3D RC network can be obtained within a few minutes on a 15-MIPS computer using this program.<
