Abstract: A system and method is provided for that allows the introduction of small sections of idealized conductive elements to be placed along a transmission line. The output is a partitioned transmission line whose segments between the idealized conductive elements are analyzed via circuit simulators as a distributed parasitic network, as opposed to the widely used lumped parasitic elements approach for the entire line. The distributed parasitic network system and method provides circuit designers with a parasitic extraction tool which allows the designer to define a transmission line segment for analysis, and create sub-networks of parasitic elements across the transmission line. These elements can then be passed to existing vendor circuit simulators for parasitic analysis, the result of which are more accurate than that derived using existing extraction tools whose output is limited to only a lumped parasitic parameter along the line.
