1. A method for modeling microelectromechanical devices, the method comprising: separating a MEMS design into an electrode module, a mass module, and a spring module, wherein the electrode module, the mass module, and the spring module are each structural regions capable of being stored within a two-dimensional mask database, at least one of the electrode module, the mass module, and the spring module being in a separate dummy layer than another one of the electrode module, the mass module, and the spring module; developing a first model for the electrode module, a second model for the mass module, and a third model for the spring module, wherein the first model comprises the following equation: F e = ∈ o ⁢ LH 2 ⁢ ⁢ D 2 ⁢ ( V m - V s ) 2 where F e is an electrostatic force, ε o is a permittivity of free space, L is a length of the electrodes, H is a height of the electrodes, D is a distance between the electrodes, V m is a main electrode voltage, and V s is a secondary electrode voltage; and entering the first model, the second model, and the third model into a MEMS model on a processing system.
