  • Patent number: 6223334
    Abstract: The present invention includes a net topology strategy, referred to as a J-tree model, that meets monotonicity and ring back constraints for nets with bi-directional drivers without much degradation in delay. The present invention includes a method that can be used to automatically construct a J-tree for a given net. A J-tree is generated by identifying at least two clusters of nodes and interconnecting the nodes so that each node has a sibling node that is the same distance from a parent node. Each cluster comprises at least a minimum geometric number of nodes. The nodes are interconnected by first locating a star point for each cluster so that the nodes in each cluster are equidistant from the star point. Then, the star point for each cluster is interconnected forming the topology.
