Classification: G06F,H05K

Abstract:
Apparatus for use with a router operable for placement of a set of conduction paths to interconnect circuit components, comprising:a processor for determining whether a level of crosstalk in the conduction paths in the set exceeds a predetermined crosstalk limit;a controller for generating a signal to operate said router, said signal representing at least information indicative of a determination by said processor; anda redesign provider for providing a reconfiguration of the set of conduction paths when the level of crosstalk exceeds the predetermined crosstalk limit, the processor re-determining whether the level of crosstalk in the conduction paths in the set corresponding to the reconfiguration exceeds the predetermined crosstalk limit, the at least information including information concerning the reconfiguration when the level of crosstalk in the conduction paths in the set corresponding to the reconfiguration does not exceed the predetermined crosstalk limit, the controller causing the router to effect placement of the set of conduction paths currently determined to have a level of crosstalk not greater than the predetermined crosstalk limit, the reconfiguration including a selected reconfiguration of at least one subset of the conduction paths including a pair of balanced transmission lines and an unbalanced transmission line, the balanced transmission line pair exchanging crosstalk with said unbalanced transmission line, the level of crosstalk being a function of a position of said unbalanced transmission line relative to the balanced transmission line pair, the selected reconfiguration involving a change in said position.
