Transient Response of Multi Chip Modules Interconnection

A derivative algorithm ofasym ptotic w aveform evaluation(AWE) w as putforw ard to study the transient response ofm ulti chip m odules(MCM). Based on the features ofthe Telegrapher's equations, Maclaurin series ofits m atrix exponentwere obtained. The series were putinto the overallcircuitm atrix as a stam p. Then the im pulse response w as gained. Finally, the arbitrary input's response w as gained by the m ethod ofrecursive convolution(RC). The results ofnum ericalsim ulation show thatthis algorithm is abouttw o orders ofm agnitude fasterthan the traditionalsim ulatorSPICEto certain degree ofaccuracy.
