Efficient extractor for post-layout simulation on memories

摘要

Embodiments of the present invention relate to a computer-controlled method for extracting cell parasitic characteristics for netlist back-annotation in a circuit that comprises a row and column array of repeated cells. The method comprises the steps of generating parasitic and connection data for a row and a column of said cells in the arrayed circuit, duplicating the generated parasitic data for an additional row and an additional column in the arrayed circuit; synthesizing connection data for the additional row from a connected cell in that additional row; synthesizing connection data for the additional column from a connected cell in that additional column, and making the generated parasitic data and the synthesized connection data available for subsequent back-annotation of the netlist.
