US 2008/0189667 A1 · Model-based design verification

Abstract

An analog design-rule-check tool analyzes a microdevice design, such as an integrated circuit design, to identify occurrences of geometric elements that share a specified relationship. When the tool identifies such an occurrence of these geometric elements, it will associate or “cluster” these geometric elements together into an identifiable unit. For specified “clusters” of geometric elements, the analog design-rule-check tool will then determine the value of a measurement or measurements required by a user. Once the analog design-rule-check tool has determined the necessary measurement values, it will use those values to evaluate the function describing a model.
