Abstract: A computerized method for designing a layout of a driver includes analyzing a schematic circuit. PMOSFETs coupled between first common nodes are grouped into one or more first classes. NMOSFETs coupled between second common nodes are grouped into one or more second classes. The method further includes generating the layout for each MOSFET at each location in a layout area of the driver by generating a super parameterized cell (PCELL) layout block comprising a master MOSFET PCELL and a master guard ring PCELL for each of the first class and the second class. The master MOSFET PCELL includes a first set of parameters for the MOSFET and the master guard ring PCELL includes a second set of parameters for the guard ring around the MOSFET. A child PCELL of the master MOSFET PCELL and the master guard ring PCELL are instantiated at each location in the layout area.
