Abstract
A system and method are provided for reducing processing time in characterizing a programmably implemented cell. The cell is decomposed into a plurality of channel connected component portions (CCC's), each including a local output node and at least one switching device establishing a conduction channel within a channel path extending from the local output node to a power plane of the cell. A component characteristic function is generated for each CCC, which logically sums a locus of vectors for nodes electrically connected to the local output node. Each CCC's component characteristic function is expanded to form a local characteristic function relative to one or more other upstream CCC. Each local characteristic function is thereby formed exclusive of any upstream local output node electrically disconnected from its local output node. At least one feasible vector is selectively generated from the local characteristic functions according to requirements predefined for a parametric measurement.
