Method and apparatus for hierarchically restructuring portions of a hierarchical database based on selected attributes

摘要

A method and apparatus for hierarchically restructuring at least a portion of a hierarchical database based on selected attributes. In one embodiment, a virtual cell (140) may use a virtual cell mapping function (130) to create a hierarchical netlist. Some embodiments may programmatically create a corresponding generated template to include in the netlist for each virtual cell. Some embodiments may generate multiple templates from the same cell. Some embodiments may generate multiple instances of different templates from the same instance in the database. One application of the present invention is for use in circuit simulation.
