Device modeling by radial basis functions

An alternative modeling technique that works directly from data and provides a straightforward and relatively automatic method of interpolating smoothly from measurements is presented. Since the results are nonexplicit (that is, the models are algorithmic rather than analytic), the approach is likely to be most appropriate in situations where it is difficult to derive an explicit functional form analogous to the Ebers-Moll equation for bipolar transistors. A good example is in the modeling of submicron devices in VLSI circuits, where the relevant device physics are currently poorly understood.<
