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

IOLTS
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

FEDfRo
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
http://tima.univ-grenoble-alpes.fr/conferences/iolts/iolts19/
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
http://patmos2019.die.upm.es
a well-established IEEE forum on Power and Timing Modeling, Optimization and Simulation.

- IVSW: the International Verification and Security Workshop
http://tima.univ-grenoble-alpes.fr/conferences/ivsw/ivsw19/ 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.

PhD thesis defenses

« Design flow and formal models for desynchronization of synchronous circuits ».

Candidate: Fra. Bertrand

Advisor: L. Fesquet

President of jury: P. Pannier

PhD: These de Doctorat, Université Grenoble Alpes

Speciality: Microélectronique

Defense: July 2nd, 2019 - 10:00, GRENOBLE INP (Viallet) - Amphi Gosse

Abstract

In the smart-cards market, contactless communication becomes more and more common. In order to reduce the cost of the systems, the power budget available reduces along with the size reduction of the antenna. Many design techniques are available to improve the efficiency of digital design. However, asynchronous designs, because of their adaptability to variable operating conditions, offer a natural solution for the contactless power supply problematics. Nevertheless, the lack of engineers trained, and proven tools, to design asynchronous circuits brakes the adoption of asynchronous designs in the industry. To address theses issues, a systematic method allowing to turn already existing synchronous designs into asynchronous micropipelines had been developed. Using a formal model, a desynchronization process was established and used on a cryptographic module which was implemented on silicon. The characterization allowed us to evaluate the relevance of the desynchronization flow but also its limitations. The efficiency of desynchronized systems depending largely on the architecture of the initial synchronous circuit, the proposed method allows a quick estimation of the performances of the desynchronized circuit, and results in functional circuits.

 

« Built-In Self-Test solutions for high-performance and reliable analog, mixed-signal, and RF integrated circuits ».

Candidate: M. Barragan

Advisor: S. Mir

PhD: HDR, Université Grenoble Alpes

Speciality: Micro et Nano Electronique

Defense: July 9th, 2019 - 10:30, GRENOBLE INP (Viallet) - Amphi Gosse

Abstract

The integration capabilities offered by current nanoscale CMOS technologies enable the fabrication of complete and very complex mixed-signal systems. However, manufacturing processes are prone to imperfections that may degrade –sometimes catastrophically– the intended functionality of the fabricated circuits. Extensive production tests are then needed in order to separate these defective or unreliable parts from functionally correct devices. Unfortunately, the co-integration of blocks of very distinct nature (analog, mixed-signal, digital, RF, ...) as well as the limited access to internal nodes in an integrated system make the test of these devices a very challenging and costly task.

BIST techniques have been proposed as a way to overcome these issues. These techniques aim at including some of the ATE functionality into the Device Under Test, in such a way that each fabricated system becomes self-testable. Applying BIST to the digital part of a complex integrated system is a common and standardized practice. Many test alternatives broadly proven in practice are available, all of them based on defect test and fault models. On the other hand, AMS-RF BIST techniques are still lagging behind due to the strict requirements imposed by the analog circuitry. Since AMS-RF circuits are usually tested by measuring their functional specifications, this means that each measurement has to comply with strict accuracy constraints to match the performance of the circuits under test.

A promising solution to these issues is the combination of BIST strategies and machine learning-based tests. Machine learning test strategies replace costly analog, mixed-signal and RF performance measurements by a set of simpler measurements that can be performed on-chip by low-cost built-in test circuitry. The core idea is to build a mapping model from a set of simple measurements to the set of functional specifications. However, this test strategy is not free of shortcomings either.

My research has been focused on overcoming the limitations of current BIST and machine learning-based test for complex AMS-RF circuits, with the final goal of providing innovative state-of-the-art test solutions for these complex systems
