Spice model bin inheritance mechanism

A system, method, and computer program product for facilitating model binning in circuit simulators. Embodiments enable specification of models spanning binning dimensions, such as device width and length, in a model group via inheritable model bins. New simulator modeling syntax and semantics eliminate much of the redundancy and parsing overhead from model parameter specifications in foundry process design kits. Indirect and optional inheritance is also enabled, allowing for fine grain and coarse grain grids in the same model group.
