Electro Optical Techniques, composed of Electro Optical Frequency Mapping (EOFM) and Probing (EOP), are dynamic optical analysis techniques. Most EOP/EOFM applications have focused on design debug or design characterization of integrated circuits (ICs), but these techniques are seldom used for global functional failure isolation.

The paper describes as integrated technique of Electro Optical Frequency Mapping (EOFM) and Electro Optical Probing (EOP) to localize open failure mode with traditional FA analysis approach. The technique was performed in analog devices on advanced SOI-based circuits.

Abstract: In this paper, a novel signal toggling technique in Electrical Optical Frequency Mapping/ Phase Mapping (EOFM/EOPM) and Electrical Optical probing (EOF) are performed to successfully localized the fault location and identify the physical defect promptly. A function square wave is asserted into the pin of interest, i.e. leakage pin or ...
