Abstract:
1. An apparatus comprising: a plurality of differential signal channel pairs (“differential pairs”) of a computing system, wherein a first differential pair and a second differential pair of the plurality of differential pairs experience crosstalk; and logic to manipulate polarity relating to at least one of first transmission links of the first differential pair and second transmission links of the second differential pair such that the polarity is switched to cancel out the crosstalk between the first differential pair and the second differential pair, wherein switching includes re-routing one or more of the first and second transmission links based on designs of the first and second differential pairs, wherein re-routing is performed via a parallel pattern re-routing scheme such that a first far-end crosstalk polarity of a vertical connection is determined by at least one of locations of the first and second differential pairs and pin polarity assignments of the first and second differential pairs, and a second far-end crosstalk polarity of a horizontal routing is determined by at least one of design rules and line polarity rules associated with the first and second differential pairs.
