摘要： A data extraction tool is provided to extract filtered connectivity and geometrical data for specified layout cell hierarchies of an integrated circuit (IC) design, e.g. a deep sub-micron IC design. The connectivity and geometrical data for each layout cell hierarchy are extracted at least in part in accordance with specified parasitic effect windows. In one embodiment, the data extraction tool includes a filtered extraction function that operates to extract connectivity and geometrical data for layout nets of each layout cell hierarchy of the IC design, one or more layout nets at a time. Additionally, one or more filtered databases are provided to store the filtered connectivity and geometrical data of the layout cell hierarchies.

摘要： A parasitic extraction tool (PEX) is provided to generate electrical modeling data for an integrated circuit (IC) design, e.g. a deep sub-micron IC design. The PEX includes a read function for reading extracted connectivity and geometrical data of various layout cell hierarchies of the IC design, that are organized and indexed by layout nets. The PEX also includes a write function for writing generated electrical modeling data into a parasitic database (PDB), which is physically organized to accommodate physical storage of the electrical modeling data in multiple physical media, and concurrent usage of the electrical data by multiple client applications, e.g. post layout analysis tool. In one embodiment, the PDB further includes an application interface that shields the physical organization of the PDB, and a logical abstraction of the physical organization to facilitate implementation of the application interface.

摘要： An improved method and system for performing extraction on an integrated circuit design is disclosed. Extraction may be performed at granularities much smaller than the entire IC design, in which a halo is used to identify a geometric volume surrounding an object of interest to identify neighboring objects and generate an electrical model. The extraction approach can be taken for Islands, Nets, as well as other granularities within the design. Re-extraction of a design can occur at granularities smaller than a net. Some approaches utilize Island-stitching to replace an island within a net. An approach is also described for improving cross-references for cross-coupled objects.

摘要： An improved method and system for stitching one or more islands of an integrated circuit design is disclosed. Multiple connected island objects in the IC design are first identified. At least one of the multiple identified connected island objects is then modified to form a modified island object. The modified island object may then be stitched into the multiple identified connected island objects. In some embodiments, stitching a modified island object may be implemented by tracking the endpoint(s), port(s), or node(s) of the connected island object being modified and stitched.
