Abstract
The present invention includes a method for modeling devices having different geometries, in which a range of interest for device geometrical variations is divided into a plurality of subregions each corresponding to a subrange of device geometrical variations. The plurality of subregions include a first type of subregions and a second type of subregions. The first or second type of subregions include one or more subregions. A regional global model is generated for each of the first type of subregions and a binning model is generated for each of the second type of subregions. The regional global model for a subregion uses one set of model parameters to comprehend the subrange of device geometrical variations corresponding to the G-type subregion. The binning model for a subregion includes binning parameters to provide continuity of the model parameters when device geometry varies across two different subregions.
