A configuration-oriented SPICE model for multiple coupled lines in an inhom
ogeneous medium is presented in this paper. The circuit model consists of a
network of uncoupled transmission lines and is readily modeled with simula
tion tools like LIBRA and SPICE, and provides an equivalent-circuit represe
ntation which is simple and topologically meaningful as compared to the mod
el based on modal decomposition. This configuration oriented model is deriv
ed by decomposing the immittance matrices associated with an n coupled-line
2n-port system. Time- and frequency-domain simulations of typical coupled-
line multiports are included to exemplify the utility of the model. The mod
el is useful for the simulation and design of general single and multilayer
coupled-line components such as filters and couplers and investigation of
signal integrity issues, including crosstalk in interconnects associated wi
th highspeed digital- and mixed-signal electronic modules and packages.
