Curriculum Vitae

Sybille Hellebrand received her Diploma in Mathematics from the University of Regensburg in 1986. In the same year she joined the Institute of Computer Design and Fault Tolerance at the University of Karlsruhe, where she finished her Ph.D. in Computer Science in 1991. From 1991 to 1992 she received a post-doctoral fellowship from the French government and continued her research work at the TIM3/IMAG Laboratory in Grenoble, France. In 1992 she joined the University of Siegen as a post-doctoral research and teaching assistant. For her habilitation project she received a Lise- Meitner Fellowship from the NRW government in 1995. Before she completed her habilitation in 1997 she spent several months as a guest researcher at Mentor Graphics Corporation in Portland, OR, USA. After her stay in the USA, Sybille Hellebrand moved to the University of Stuttgart as a permanent research and teaching assistant. In 1999 she was appointed full professor in Computer Science at the University of Innsbruck, Austria.

Since December 2004 she holds the chair for Computer Engineering at the Institute of Electrical Engineering and Information Technology at the University of Paderborn. Sybille Hellebrand is a member of the Institute of Electrical and Electronics Engineers (IEEE) and the IEEE Test Technology Technical Council (TTTC). She has served on the program committees of many international conferences, and she was the General Chair of the IEEE European Test Symposium in 2014. She is an associate editor of the Journal of Electronic Testing – Theory and Applications (JETTA). From 2002 to 2009 she was a member of the editorial board of IEEE Transactions on Computer-Aided Design of Circuits and Systems. Her main research interests are in test, diagnosis, and fault tolerance of integrated circuits and systems.

Stress-Aware Periodic Test of Interconnects

S. Sadeghi-Kohan, S. Hellebrand, H. Wunderlich, Journal of Electronic Testing (2022)

Abstract

DOI

Safety-critical systems have to follow extremely high dependability requirements as specified in the standards for automotive, air, and space applications. The required high fault coverage at runtime is usually obtained by a combination of concurrent error detection or correction and periodic tests within rather short time intervals. The concurrent scheme ensures the integrity of computed results while the periodic test has to identify potential aging problems and to prevent any fault accumulation which may invalidate the concurrent error detection mechanism. Such periodic built-in self-test (BIST) schemes are already commercialized for memories and for random logic. The paper at hand extends this approach to interconnect structures. A BIST scheme is presented which targets interconnect defects before they will actually affect the system functionality at nominal speed. A BIST schedule is developed which significantly reduces aging caused by electromigration during the lifetime application of the periodic test.

Abstract

Marginal hardware introduces severe reliability threats throughout the life cycle of a system. Although marginalities may not affect the functionality of a circuit immediately after manufacturing, they can degrade into hard failures and must be screened out during manufacturing test to prevent early life failures. Furthermore, their evolution in the field must be proactively monitored by periodic tests before actual failures occur. In recent years small delay faults have gained increasing attention as possible indicators of marginal hardware. However, small delay faults on short paths may be undetectable even with advanced timing aware ATPG. Faster-than-at-speed test (FAST) can detect such hidden delay faults, but so far FAST has mainly been restricted to manufacturing test.

A Hybrid Space Compactor for Adaptive X-Handling

M.U. Maaz, A. Sprenger, S. Hellebrand, in: 50th IEEE International Test Conference (ITC), IEEE, 2019, pp. 1-8

Abstract

The test for small delay faults is of major importance for predicting potential early life failures or wearout problems. Typically, a faster-than-at-speed test (FAST) with sev¬eral different frequencies is used to detect also hidden small delays, which can only be propagated over short paths. But then the outputs at the end of long paths may no longer reach their stable values at the nominal observation time and must be considered as unknown (X-values). Thus, test response compaction for FAST must be extremely flexible to cope with high X-rates, which also vary with the test frequencies. Stochastic compaction introduced by Mitra et al. is controlled by weighted pseudo-random signals allowing for easy adaptation to varying conditions. As demonstrated in previous work, the pseudo-random control can be optimized for high fault efficiency or X-reduction, but a given target in fault efficiency cannot be guaranteed. To close this gap, a hybrid space compactor is introduced in this paper. It is based on the observation that many faults are lost in the compaction of relatively few critical test patterns. For these critical patterns a deterministic compaction phase is added to the test, where the existing compactor structure is re-used, but controlled by specifically determined control vectors.
