A quick spice simulation of cascaded lossless coupled interconnections: Topic 10: Computer aided design and modelling

An application of modal method to simulate the lossless interconnections having many successive coupled or non-coupled sections is presented. A modal transformation must be made at each common point between two successive sections. Time-domain simulations on SPICE software are performed using a modal equivalent circuit including linear or non-linear sources or loads. A typical example of spurious commutations of logic gates due to coupling effect is presented.
