Developing complex electronic systems can be a great challenge for design engineers especially regarding electromagnetic compatibility aspects of the cables connecting the separate components. The new standard in development is the 42V system, which will allow for smaller cables, but many more EMC problems will occur. The ongoing trend towards higher complexity, functionality and flexibility of harness systems together with the growing need to reduce their space consumption and weight typically result in non-ideal cable shielding. Additional measurement efforts would be necessary to cope with the problems arising when one has to investigate signal integrity and EMC behavior of such electronic interconnects. CableMod provides the user an efficient software tool for modeling and simulation of complex cable structures to overcome this bottleneck. CableMod includes powerful two-dimensional field solvers (Static2D - see below) for the determination of transmission line characteristics and a Spice-equivalent network simulator for calculating the currents and voltages in the excited conductor systems. Even though CableMod has it's own built-in CAD tool for design, CableMod also accepts Nastran file outputs from Catia or UniGraphics and can produce outputs for frequency/time domain analysis (I/V, s-parameter, distributed or lumped spice, distributed or lumped Saber, T model) and radiation calculations with SimLab's RadiaSim. The statistical bundling algorithm can be fixed, parameter, or Monte-Carlo, with variations in material dielectric losses, ohmic losses, cable, bundling, analysis, etc. CableMod can also handle no ground, non-ideal ground, or partial area ground planes, together with statistical material variations in conductivities.
