25th IEEE International Symposium on On-Line Testing and Robust System Design

Venue: Rhodes Island, GREECE
Date: July 1-3, 2019

finance chair : ANGHEL L., VELAZCO R. general chair : NICOLAIDIS M. local organization : FOURNERET-ITIÉ A.-L., SIMEU E., ZERGAINOH N. - E. publication chair : PAPAVRAMIDOU P. steering committee member : NICOLAIDIS M. technical program committee : ANGHEL L., BARRAGAN M., BENABDENBI M., DI NATALE Giorgio, LEVEUGLE R., MIR S., NICOLAIDIS M., PAPAVRAMIDOU P., SIMEU E., VATAJELU E.I.

Summary: Issues related to On-line testing techniques, and more generally to design for robustness, are increasingly important in modern electronic systems. In particular, the huge complexity of electronic systems has led to growth in reliability needs in several application domains as well as pressure for low cost products. There is a corresponding increasing demand for cost-effective design for robustness techniques. These needs have increased dramatically with the introduction of nanometer technologies, which impact adversely noise margins; process, voltage and temperature variations; aging and wear-out; soft error and EMI sensitivity; power density and heating; and make mandatory the use of design for robustness techniques for extending, yield, reliability, and lifetime of modern SoCs. Design for reliability becomes also mandatory for reducing power dissipation, as voltage reduction, often used to reduce power, strongly affects reliability by reducing noise margins and thus the sensitivity to soft-errors and EMI, and by increasing circuit delays and thus the severity of timing faults. There is also a strong relation between Design for Reliability and Design for Security, as security attacks are often fault-based.

The International Symposium on On-Line Testing and Robust System Design (IOLTS), is an established forum for presenting novel ideas and experimental data on these areas. The Symposium is sponsored by the IEEE Council on Electronic Design Automation (CEDA) and the 2019 edition is organized by the IEEE Computer Society Test Technology Technical Council, the University of Athens, and the TIMA Laboratory.

4th IEEE Federative Event on Design for Robustness

Venue: Rhodes Island, GREECE
Date: July 1-3, 2019

general chair : NICOLAIDIS M.

Summary: The pervasiveness of electronic systems in modern societies raises drastically the requirements to protect them against intentional attacks affecting security.

Nanometric scaling and the related aggressive reduction of device geometries steadily worsens noise margins; process, voltage and temperature variations; aging and wear-out; soft error and EMI sensitivity; power density and heating; which are also worsening by the rapidly increasing complexity of modern SoCs. It is therefore mandatory mitigating these issues, for achieving acceptable levels of yield, reliability, and lifespan. Furthermore, these issues are making increasingly difficult meeting low power and high performance, which are paramount requirements in modern SoCs and numerous applications. Indeed:

- Extra circuitry used in fault mitigation architectures increases power;

- Supply voltage reduction (often used to reduce power), affects yield, reliability, and lifespan, as it reduces noise margins and increases therefore the sensitivity to soft-errors and EMI, and also increases circuit delays that increases the sensitivity to timing faults;

- Furthermore: Reducing supply voltage for reducing power affects performance as it increases circuit delays; Increasing clock frequency for increasing performance, affects yield, reliability, and lifespan, as it increases the sensitivity to timing faults and soft-errors, and it also affects power as it increases dynamic power and may also require increasing supply voltage for reducing circuit delays.

- Design for Timing is also further related with Design for Reliability, as in real time systems timing properties are as important as functional properties in delivering correct operation.

These trends have made mandatory the development of efficient Design for Robustness approaches for mitigating these pluralities of threats. However, as Robustness-related DfX techniques are proliferating (Design for Test, Design for Debug, Design for Yield, Design for Reliability, Design for Low-Power, Design for Timing Performance, Design for Security, Design for Verification, …), and also as these techniques often weaken the goals of each other, it is often very difficult to guarantee that a design meets all its target specifications. Thus, it becomes mandatory to address all these techniques holistically in order to improve their global efficiency: achieve all the robustness requirements of each design, and moderate their cost. There is therefore a major need for a consolidated international forum bringing together specialists from all these domains to enhance interactions and cross-fertilization. The IEEE Federative Event on Design for Robustness (FEDfRo), was initiated to meet this goal by bringing together:

- IOLTS: International Symposium on On-Line Testing and Robust System Design
a well-established IEEE forum on Design for Quality, Design for Yield, Design for Reliability, and Low-Power design based on Design for Reliability approaches, mostly addressing digital systems;

- PATMOS: International Symposium on Power and Timing Modeling, Optimization and Simulation
a well-established IEEE forum on Power and Timing Modeling, Optimization and Simulation.

- IVSW: the International Verification and Security Workshop a new IEEE forum started on 2016 and addressing all Verification and Security issues associated with electronic systems.

These events are holding in the same location and are running in parallel. To encourage interactions, anyone registered in any of them can freely attend sessions of the other three events. All social activities are also done jointly for increasing interactions and technology cross-fertilization among attendees.

Dans le monde des smartcards, le besoin de communications via des dispositifs radio fréquences est de plus en plus courant. Le coût étant un point critique pour ces dispositifs, l’antenne, et la quantité d’énergie récupérée par celle-ci, à tendance à être réduite. Pour suivre cette contrainte, de nombreuses solutions techniques améliorant l’efficacité énergétique des circuits numériques synchrones existent. Néanmoins, les circuits asynchrones, s’adaptant naturellement aux conditions d’opération qui lui sont appliquées, fournissent une solution particulièrement adaptée aux problématiques liées à télé-alimentation. Cependant, le manque de formation des ingénieurs, et d’outils qualifié, pour la conception de circuits asynchrones rend marginale leur utilisation dans un cadre industriel. Pour remédier à ces difficultés, une méthode systématique permettant de traduire une spécification synchrone en un circuit asynchrone micropipeline a été développée. Exploitant des modèles formels, un flot de désynchronisation a été mis en place et exercé sur un module cryptographique pour aboutir à une implémentation sur silicium. La caractérisation de ce circuit nous a montré la pertinence de la désynchronisation mais aussi ses limites. L’efficacité de la désynchronisation dépendant fortement de l’architecture du circuit synchrone initialement considéré, le flot proposé permet de rapidement estimer les performances du circuit désynchronisé, mais aussi d’obtenir un circuit physique fonctionnel.
