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.

Generating rules for nets that cross package boundaries

A method, apparatus and program product oversee and coordinate the automatic generation, monitoring and submission of package files and other modeling processes to enable focused, flexible and efficient modeling of design performance characteristics.

Simulation management system

A method, apparatus and program product generate package files that are separately stored and selectively combined to generate a net file suited for system simulation and analysis. Selective combination of the package files using respective reference connections of each package enables focused and efficient modeling of design performance characteristics.
