Abstract
A method for performing circuit analysis on an integrated-circuit design having design data available in different forms is disclosed. In accordance with the method and system of the present invention, the integrated-circuit design includes multiple networks, and the different forms of design data may appear within one of the networks. For all of the networks within the integrated-circuit design, different forms of design data are categorized into at least three databases. The first of the at least three databases may contain three-dimensional extraction information, the second of the databases may contain wiring information, and the third of the databases may contain pre-wiring information. For each of the networks, a determination is made as to whether or not three-dimensional extraction information is available. In response to a determination that three-dimensional extraction information is available, performing circuit analysis by utilizing the three-dimensional extraction information.
