Method and system for automated schematic diagram conversion to support semiconductor body bias designs
View Patent ↗A computer implemented method and system for converting schematic diagrams. The method includes accessing a first set of schematic diagrams, wherein the schematic diagrams represent an integrated circuit design to be realized in physical form. A plurality of a first type of circuit elements in the first set are converted into a second type of circuit elements. The conversion is implemented in accordance with a set of conversion rules. A second set of schematic diagrams representing the integrated circuit design and including the second type of circuit elements are then output.
