System and method for creating hybrid resistance and capacitance (RC) netlist using three-dimensional RC extraction and 2.5 dimensional RC extraction

摘要

One or more systems and methods for a cell based hybrid resistance and capacitance (RC) extraction are provided. The method includes generating a layout for a semiconductor arrangement, performing a three-dimensional (3D) RC extraction on a target unit cell to obtain a 3D RC result including a coupling capacitance between unit cells, generating a 3D RC netlist based upon the 3D RC result, performing a 2.5 dimensional (2.5D) RC extraction on a peripheral cell to obtain a 2.5D RC netlist, and combining the 3D RC netlist with the 2.5D RC netlist to create a hybrid RC netlist for the layout. In some embodiments, the hybrid RC netlist is generated by stitching the coupling capacitance for at least one of the target unit cell, a repeating unit cell, or the peripheral cell together. In some embodiments, the 3D RC result for the target unit cell is stitched to the repeating unit cell.
