This paper presents a novel flexible concurrent testing scheme for non-feedback and feedback bridging faults in integrated circuits. All the existing concurrent testing schemes for non-feedback and feedback bridging faults available in the literature are designed with very straightforward manner and these schemes do not provide any idea regarding flexibility in design of the tester circuit. However, providing flexibility in design of the tester circuit is one of the important criteria to be included in concurrent testing of modern integrated circuits. To the best of my knowledge, the proposed scheme will be treated as first concurrent testing scheme that provides flexibility in design of the tester circuit for both non-feedback and feedback bridging faults. This work aims to provide flexibility in tester circuit design by dropping some of wires that are tapped from Circuit Under Test (CUT) to the tester circuit. Dropping some of tap wires from CUT to the tester circuit reduces load on CUT and this helps in reducing the area overhead of the tester circuit. Thus, flexibility in concurrent testing is achieved by dropping some of tap wires during design of tester circuit. Further, dropping some of tap wires (flexibility) in tester circuit design provides a trades-off analysis between area overhead, fault coverage and fault detection latency. The proposed scheme is verified using different ISCAS89 benchmark circuits and results illustrate that flexibility in design of tester circuit is achieved through dropping some of tap wires from CUT to the tester circuit. Further, it reduces area overhead greatly with minimal compromise in fault coverage. [ABSTRACT FROM AUTHOR] |
