HIERARCHIAL SEMICONDUCTOR DESIGN

Hierarchical semiconductor structure design is disclosed. One aspect of the invention is a computerized system that includes a semiconductor structure (such as a semiconductor test structure) and a basic atom. The system also includes a hierarchy of abstractions ordered from highest to lowest. Each abstraction relates a plurality of instances of an immediately lower abstraction; the highest abstraction corresponds to the structure, and the lowest abstraction corresponds to the basic atom. A plurality of sets of parameters also is included within the system, where each set of parameters corresponds to an instance of an abstraction. 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.
