Design for Reliability: From Devices to Systems

Part-1: Origin, characterization and compact modelling of device aging Speaker: Prof. Montserrat Nafría, UAB, Spain.
Part-2: Reliability-aware design Speaker: Dr. Elisenda Roca, IMSE-CNM, Spain
Part-3: Quantifying and mitigating aging effects at the system level Speaker: Dr. Hussam Amrouch, KIT, Germany

Throughout technology scaling, sustaining reliability has become extraordinary challenging. Key to the design of reliable circuits and systems is to account for the uncertainty introduced in the electrical characteristics of devices by Time Zero Variability (TZV), also known as process variations, and Time Dependent Variability (TDV) phenomena (such as Random Telegraph Noise, Bias Temperature Instabilities and Channel Hot Carriers Injection) and its impact on circuits and systems. This tutorial will present the newest research results in reliability from ground up; starting from physics where reliability degradations do originate all the way up to the system level where their ultimate impact finally takes place.
In the first part of the tutorial, the physics behind TDV phenomena, the characterization challenges in advanced nodes and their compact modeling will be addressed. The second part of the tutorial will use these stochastic compact models to build circuit simulators accounting for this reliability information. They constitute the cornerstone of new reliability-aware design methodologies and tools that help designers to optimize the circuit lifetime. In the last part of the tutorial, we will demonstrate how reliability awareness can be brought to the existing EDA tool flows, which enables designers to proactively build more resilient circuits. This is done through so-called reliability-aware cell libraries. We will show how using these libraries will allow designers to also quantify the ultimate impact of aging at the system level. Finally, we will explain how approximate computing principles can be explored in the context of aging towards maximizing the efficiency.

Prof. Montserrat Nafría received the Ph.D. degree in Physics from the Universitat Autonoma de Barcelona, Spain, in 1993, where she is currently a Full Professor at the Department of Electronic Engineering. Her major research interests include CMOS device and circuit reliability. Currently, she is working on the characterization and modelling of the aging (BTI and channel hot carrier degradations) and variability of advanced MOS devices. This is done from the nanoscale level, by studying the phenomena using Atomic Force Microscope-related techniques, up to circuit level, by developing models for circuit simulators that account for the time-dependent variability of the devices. She is also interested in the characterization and modelling of Resistive RAM and graphene-based devices. She is the author or coauthor of more than 250 research papers in scientific journals and conferences in all these fields.

From Power Management to Energetic Intelligence:
an evolutionary challenge for students, educators and designers

Prof. Nicola Femia, University of Salerno

Power Management Circuits and Systems provide electrical energy to all the objects making our life more comfortable, safer and funnier, like smart phones and watches, aircraft and automobiles, implanted prostheses and magnetic resonance machines, blenders and microwave ovens, robots and drones, digital TV sets and personal computers. The Design of Power Management Circuits and Systems is an exciting intellectual dare for students and educators, as it stimulates insight of interdisciplinary knowledge, understanding of new technologies, exploration of unconventional design solutions, discovery of the power of mathematics, reinforcement of problem solving capability, intelligent use of the energy and ultimately preservation of the environment and of the Earth's resources.
Power Management Circuits and Systems have today to implement much more enhanced energy processing functions than in the past, thus bridging power designers into the era of Energetic Intelligence. University education and industry training has to coherently enhance, to proactively drive this evolution and to guide talented students and designers towards the achievement of powerful professional skills. The presentation intends to overview power management design issues and to propose a vision of the knowledge and tools needed to win the challenges of Energetic Intelligence.
