1. A method for performing an electronic design automation (EDA) analysis, the method comprising: selecting a cell in a circuit design; determining a value for a first operational parameter associated with the cell; selecting a mathematical model for a performance parameter of the cell from a cell library, the mathematical model being a function of a first input variable; generating a value for the first input variable by applying a first preconditioning function to the value for the first operational parameter, the first preconditioning function being associated with the mathematical model in the cell library; and generating a value for the performance parameter of the cell by substituting the value for the first operational parameter into the mathematical model.
