    • A method includes providing an integrated circuit device comprising a plurality of input parameters and an electrical parameter. A simulation is performed using a simulation model to simulate a plurality of data of the electrical parameter, wherein the plurality of data are generated through simulation from a first plurality of input parameter sets reflecting values of the plurality of input parameters, and wherein the plurality of data is distributed in a range. A first sub-range among the range is selected. All of the plurality of data falling into the first sub-range are selected, and are fitted with corresponding ones of the first input parameter sets to generate a first function, wherein the electrical parameter is expressed as the first function of the plurality of input parameters. The first function is different from functions in the simulation model.
