11:00 – 12:20 – KEYNOTE – Green Technologies for Intelligent and Connected Circuits & Systems Powered by Renewable Energy Sources
Massimo Alioto (NUS, Singapore)
Location: SBCCI Synopsys Auditorium
Chair: Nuno Roma (IST, Portugal)

ABSTRACT: The growth in the number of connected devices towards the trillion scale will be fundamentally impeded by batteries as a conventional source of energy, as their deployment in the trillions poses clear economic, logistical and environmental sustainability challenges.
This keynote introduces the key ideas and their silicon demonstrations to enable a new breed of always-on silicon systems from sensing, to computing and wireless communications with no battery inside (or any other energy storage). Sensor interfaces, processors and wireless transceivers fitting existing infrastructure (e.g., WiFi) with power reductions by orders of magnitude are discussed and exemplified by recent silicon demonstrations, and their system integration.
Ultimately, the technological pathway discussed in this keynote supports sustainable growth of applications leveraging large-scale deployments of silicon systems, making our planet smarter. And greener too.

11:00 – 12:20 – KEYNOTE – Reliability of VLSI technologies: impediment and opportunity
Ben Kaczer (IMEC, Belgium)
Location: SBMicro Cadence Auditorium
Chair: Gilson Wirth (UFRGS, Brazil)

ABSTRACT: Presence of non-idealities and defects in VLSI technologies is an immutable reality, which, however, is often overlooked by device engineers, researchers, technologists, and designers alike. We argue that in fact VLSI reliability “makes or breaks” any new technology. Superficial device reliability optimization is possible using phenomenological observations only, but we argue that solid physical foundations and thorough understanding of the underlying degradation mechanisms are essential both for truly dependable lifetime projections and for novel device pathfinding. Based on the detailed investigation of gate oxide defects, our “defect engineering” approach enables, among other things, optimization paths for SiGe channel devices and new oxidation techniques for advanced gate-all-around architectures, such as nanosheets and forksheets. In deeply scaled devices, degradation mechanisms can be decomposed down to individual defects, with each defect measured separately and its properties described down to single Kelvin temperatures using quantum mechanics. Such knowledge then allows us e.g. to model the degradation statistics of deeply-scaled devices and to predict the likelihoods of their failure. Robust degradation models enable us to project wider safe operating areas, which in turn allow to design better-performing circuitry at a given technology node and thus limited costs. Moreover, the ubiquitous presence of defects can be in fact embraced and the in-depth knowledge of defect properties can be used to our advantage to design new devices and applications, ranging from memory to physically unclonable functions and tamper-aware aging monitors.

Alan Mishchenko (University of California, Berkeley, USA)
Location: SBMicro Cadence Auditorium
Chair: André Reis (UFRGS, Brazil)

ABSTRACT: Given the progress achieved over the last fifty years in logic synthesis and verification, it is tempting to believe that most of the research discoveries have already been made, and the role of future researchers and engineers is just to maintain the CAD tools and occasionally make small changes, such as adding concurrency or employing machine learning to generate better scripts. Nothing could be farther from the truth. In this talk, we explore several orthogonal innovations in the fundamental research used to build synthesis tools targeting FPGAs and ASICs. These innovations include using novel data structures, leveraging synergistic optimization engines, and simultaneously exploring previously-unrelated search spaces. Most of these improvements are work-in-progress with early results demonstrating better quality and faster runtimes.

BIO: Alan graduated with M.S. from Moscow Institute of Physics and Technology (Moscow, Russia) in 1993 and received his Ph.D. from Glushkov Institute of Cybernetics (Kiev, Ukraine) in 1997. In 2002, Alan joined the EECS Department at University of California, Berkeley, where he is currently a full researcher. His research is in computationally efficient logic synthesis, formal verification, and machine learning.
