ABSTRACT:
An embodiment of the invention involves: providing a database that includes layout information representing a layout within an integrated circuit of an electrical circuit; identifying from the information in the database each conductive path of a selected type in the electrical circuit; extracting layout information from the database for each conductive path of the selected type; and calculating an electrical parameter for each conductive path of the selected type, as a function of the layout information obtained for that conductive path during the extracting. In addition, in a different configuration of the embodiment, a report can be generated containing information based on the electrical parameter calculated during the calculating for at least one of the conductive paths of the selected type.
