Low-Power Design of Digital VLSI Circuits around the Point of First Failure

As an increase of intelligent and self-powered devices is forecasted for our future everyday life, the implementation of energy-autonomous devices that can wirelessly communicate data from sensors is crucial. Even though techniques such as voltage scaling ...

End-to-End Industrial Study of Retiming

Giovanni De Micheli, Cunxi Yu, Maciej Jerzy Ciesielski

Sequential circuits are combinational circuits that are separated by registers. Retiming is considered as the most promising technique for optimizing sequential circuits, that involves moving the edge-triggered registers across the combinational logic with ...

MEMS Generator Study for an Embedded Energy Harvesting System

Jasha Poliakine

This work has been triggered by an industrial project targeting the development of a novel regulation system for a mechanical watch. Mechanical watches have been known for over a century as one of the finest example of energy autonomous devices, embodying ...

Signaling in 3-D integrated circuits, benefits and challenges

Somayyeh Rahimian Omam

Three-dimensional (3-D) or vertical integration is a design and packaging paradigm that can mitigate many of the increasing challenges related to the design of modern integrated systems. 3-D circuits have recently been at the spotlight, since these circuit ...

A fully modular tool for small-signal stability analysis of hydroelectric systems

Philippe Allenbach, Pedro Camilo de Oliveira e Silva, Basile Kawkabani, Sébastien Alligné

In electrical systems, the small-signal stability analysis method is usually applied to synchronous machines by using the Park representation (d, q-components). This paper presents the generalization of a different approach for this method, based on a, b, ...

An Enhanced Design Methodology for Resonant Clock Trees

Giovanni De Micheli, Xifan Tang, Vasileios Pavlidis, Somayyeh Rahimian Omam

Clock distribution networks consume a considerable portion of the power dissipated by synchronous circuits. In conventional clock distribution networks, clock buffers are inserted to retain signal integrity along the long interconnects, which, in turn, sig ...

Consensus in the presence of mortal Byzantine faulty processes

Martin Biely

We consider the problem of reaching agreement in distributed systems in which some processes may deviate from their prescribed behavior before they eventually crash. We call this failure model "mortal Byzantine". After discussing some application examples ...

Of Choices, Failures and Asynchrony: The Many Faces of Set Agreement

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

Set agreement is a fundamental problem in distributed computing in which processes collectively choose a small subset of values from a larger set of proposals. The impossibility of fault-tolerant set agreement in asynchronous networks is one of the seminal ...

A statistical method for draft tube pressure pulsation analysis

Nicolas Ruchonnet

Draft tube pressure pulsation (DTPP) in Francis turbines is composed of various components originating from different physical phenomena. These components may be separated because they differ by their spatial relationships and by their propagation mechanis ...
