Abstract
Automated routing of signal nets for interposer designs. Signal nets are defined by their endpoints (bumps). The nets and their corresponding bumps are assigned to bump groups, based on the relative locations of the bumps and also based on length-matching constraints for the nets. Some of the bump groups may be “clones,” where the routing for one bump group may also be applied to its clone. In order for two bump groups to be clones, the bumps in the two bump groups must have a same relative position (i.e., same bump pattern), and the nets in the two bump groups must be subject to the same length-matching constraint. The routing through the interposer for one of the clones is determined, and that routing is then replicated for the other clones.
