<p>Method for evaluating the effects of an interconnection on electrical variables The invention relates to a method for evaluating the effects of a multiconductor interconnection on electrical variables in an electronic circuit or system, which takes into account the frequency dependent couplings between the conductors to obtain an accurate evaluation of effects such as propagation delay, attenuation, linear distortions, echo and crosstalk. The method comprises the steps of: identifying (1) segments having suitable properties; defining (2), for each segment, a per-unit-length external impedance matrix of the segment and a per-unit-length internal impedance matrix of the segment; defining (3), for each segment, a model of the per-unit-length internal impedance matrix of the segment; and simulating (4) the circuit using, for each segment, a multiconductor transmission line model and the model of the per-unit-length internal impedance matrix of the segment defined at the previous step.</p> |
