Abstract
A data processing system and method are disclosed for efficiently determining a total return current spread at an evaluation point in a reference plane in a printed circuit board. A plurality of critical ones of a plurality of traces included within the printed circuit board are identified. For each one of the plurality of critical ones of the plurality of traces, a return current function is determined including a return current value produced by only each one of the plurality of critical ones of the plurality of traces at each point in the reference plane. A total return current spread is determined at the evaluation point utilizing the return current function associated with each one of the plurality of critical ones of the plurality of traces.
