<p>A device extractor (120) for extracting devices from a hierarchical cell design (206). The device extractor (120) selects a cell from the lowest level of the hierarchy and searches the cell for the device components. The device extractor (120) searches each cell in the lowest level and then selects a 'parent' cell in the penultimate level. The parent cell, and all of the children cells of the parent cell, are searched. The selection and search process continues until all of the components of the device (208) are identified in a cell or the children cell of the cell and a proper relationship between the components is determined. The components of the identified device (208) are masked so that they are not identified and associated with another device during subsequent searches.</p> |
