Abstract
Methods and systems for interconnecting circuit components with track patterns are disclosed. The method identifies a source pin on a first track and a destination pin on a second track and determines a third track in a different routing direction based on design rules governing track patterns. The method further determines a transition pattern for the interconnection between the source pin and the destination pin by using at least the third track. The method may use one or more dummy pins or ordering of pin connections in implementing the interconnection to satisfy certain design rules. The lengths of some wire segments of the interconnection may be further adjusted to satisfy certain design rules. Compaction may be performed to have two wire segments share the same track while the lengths or widths of one or both wire segments may be further modified to ensure design rule compliance.
