    摘要: In an embodiment, data models are stitched into a stitched data model, where each of the data models has nets and at least one of the nets crosses a package boundary. A subset of the nets from the stitched data model are selected based on a constraint, and the subset is stitched into a common rule. In various embodiments, the constraints may include a wire length, a name of the nets, and maximum numbers of vias or T-connections. If the nets are completely wired, then wire segments between nodes of the nets are connected and nodes that include non-branching vias are moved. If the nets are not completely wired, then for any of the nets that have an open connection, a rule is found with a same number of the nodes as the net with the open connection, and the nets are ordered based on the rule.
