Abstract

A technique is described whereby the physical layout of electronic circuitry is examined, and crosstalk-zone maps are maintained in the analysis of potential crosstalk problems. The crosstalk-zone maps contain the data needed to provide the required routing of wires and connections to avoid and solve electrical crosstalk problems. Crosstalk typically refers to an electrical phenomena which occurs as a result of wires or connections which are in close proximity to one another, whereby signals of one circuit affect the signals of other circuits. Crosstalk must be taken into account in the layout of a circuit chip, card, board or other packaging, so as to prevent erroneous functioning of the circuit.
