Abstract
The present invention provides a system and computer implemented method for generating a layout of a cell defining a circuit component, the layout providing a layout pattern for a target process technology. In accordance with the method, a process technology independent layout representation associated with the circuit component is input, the process technology independent layout representation being defined within a grid array providing a plurality of grid locations. A mapping database is provided having a priority ordered list of mapping entries, each mapping entry storing a process technology independent layout section and an associated layout pattern section for the target process technology. For selected grid locations within the grid array, a lookup operation is performed in the mapping database to determine a matching mapping entry, the matching mapping entry being a highest priority mapping entry within the priority ordered list whose process technology independent layout section matches a portion of the process technology independent layout representation at that selected grid location. The layout of the cell is then generated by incorporating, at each of the selected grid locations, the layout pattern section for the target process technology stored in the matching mapping entry. This provides an automated mechanism for generating cells whose layouts conform to a target process technology.
