Abstract: | This paper presents a built-in self-test (BIST) scheme for detecting all robustly testable multiple stuck-open faults confined
to any single complex cell of a CMOS circuit. The test pattern generator (TPG) generates alln·2
n
single-input-change (SIC) ordered test pairs for ann-input circuit-under-test (CUT) contained in a sequence of length 2n·2
n
. The proposed design is universal, i.e., independent of the structure and functionality of the CUT. A counter that counts
the number of alternate transitions at the output of the CUT, is used as a signature analyzer (SA). The design of TPG and
SA is simple and no special design-or synthesis-for-testability techniques and/or additional control lines are needed.
Hafizur Rahman received his Bachelor degree in electrical engineering from the University of Calcutta, India in 1986, Master degree in electrical
engineering from the Jadavpur University, India in 1988. He is at present on the faculty of the Indian Institute of Information
Technology, Calcutta, India. His research interests include VLSI testing and logic synthesis.
Debesh K. Das received his Bachelor and Master degrees in, electronics and telecommunication engineering and the Ph.D. degree in computer
science and engineering from the Jadavpur University, India in 1982, 1984, and 1997 respectively. His research interests include
VLSI testing and logic synthesis.
Bhargab B. Bhattacharya received the B.Sc. degree in physics from the Presidency College, Calcutta, India, in 1971, the B.Tech. and M.Tech. degrees
in radiophysics and electronics, and the Ph.D. degree in computer science all from the University of Calcutta in 1974, 1976,
and 1986 respectively. Since 1982, he has been on the faculty of the Indian Statistical Institute, Calcutta, where he became
full professor in 1991. As a visiting professor, he had been with the Department of Computer Science and Engineering, University
of Nebraska-Lincoln, USA, during 1985–1987, and 2001–2002. In the summers of 1998, 1999, and 2000, he visited the Fault-Tolerant
Computing Group, Institute of Informatics at the University of Potsdam, Germany. His research interests include logic synthesis
and testing of VLSI circuits, graph algorithms, and image processing. He has published more than 100 papers in archival journals
and refereed conference proceedings. Currently, he is collaborating with Intel Corporation, USA and IRISA, France, for development
of image processing hardware, and reconfigurable parallel computing tools. Dr. Bhattacharya is a Fellow of the Indian National
Academy of Engineering. He served on the conference committees of the International Test Conference (ITC), the Asian Test
Symposium (ATS), the VLSI Design and Test Workshop (VDAT), the International Conference on Advanced Computing (ADCOMP), and
the International Conference on High-Performance Computing (HiPC). For the International Conference on VLSI Design, he served
as Tutorial Co-Chair in 1994, as Program Co-Chair in 1997, and as General Co-Chair in 2000. |
