1. A computerized system comprising: a semiconductor structure; a basic atom; a hierarchy of abstractions ordered from highest to lowest, each abstraction relating a plurality of instances of an immediately lower abstraction, the highest abstraction corresponding to the structure, and the lowest abstraction corresponding to the basic atom; and, a plurality of sets of parameters, each set of parameters corresponding to an instance of an abstraction, such that changing one of the set of parameters for an instance changes at least one of the set of parameters for an instance of an immediately lower abstraction.
