Abstract

The purpose of this paper is to present a methodology for circuit and realistic fault extraction, and its implementation in a new tool, lobs, to be included in a virtual test environment, DOTLab. Digital, analog and mixed signal ICs, implemented in CMOS, bipolar or BiCMOS technologies are handled, both in Manhattan and 45 degrees geometries. Higher level design data, obtained in the top-down design flow, is used for realistic fault characterization. A sliding window algorithm is extended for fault extraction of non-orthogonal geometries. An accurate critical area evaluation algorithm is proposed, to compute the probability of occurrence of the defects. Over 100,000 transistor ICs are analyzed for bridging defects.
