Project: New Asynchronous Protocols for Enhancing Area and Throughput in Bundled-Data Pipelines

Authors: Jean SIMATIC (TIMA, CDSI), Abdelkarim CHERKAOUI (TIMA, CDSI), Rodrigo POSSAMAI-BASTOS (TIMA, CDSI) and Laurent FESQUET (TIMA, CDSI)

Abstract: This paper presents two new area-reduced controllers for bundled-data asynchronous pipelines in which the stages have long critical paths. The proposed protocols allow to reduce the number of required delay elements by using the falling edge of the asynchronous request to indicate data validity. For critical path lengths of 25 gates, the first presented scheme decreases the controller area by 48% and slightly increases the maximum throughput (2%) in comparison to a standard micropipeline implementation. The other more-concurrent scheme proposition leads to a 25% area reduction and a 40% improvement of the maximum pipeline throughput.

Title: "Modeling and operating temperature tuning of a thermally activated piezoelectric generator"

Authors: Adrian RENDON-HERNANDEZ and Skandar BASROUR

Abstract: This paper deals with the finite element model of a thermally activated piezoelectric generator. Furthermore, it presents an experimentally validated temperature tuning technique based on the gap distance of the triggering system. The working principle of proposed generator relies on the multi step thermal-to-mechanical-to-electrical energy conversion, overcoming inconveniences related to fast temporal temperatura variations and large temperature differences for efficient operating of classical direct thermal energy conversion. Performance optimization can be done in the form of temperature span tuning by changing the gap distance. By increasing this parameter, it is possible to maximize the Energy up to 10 times. Experimental data suggests that output energy up to 67 μW is possible when optimal gap distance is set. This corresponds to a power density of 103 μWcm-3

Title: On-the-fly and sub-gate-delay resolution TDC based on self-timed ring: A proof of concept.

Authors: Assia EL-HADBI (TIMA, CDSI), Abdelkarim CHERKAOUI (TIMA, CDSI), Oussama ELISSATI (INPT, STRS), Jean SIMATIC (TIMA, CDSI) and Laurent FESQUET (TIMA, CDSI)

Abstract: A new fully digital high resolution time-to-digital converter (TDC) based on a self-timed ring oscillator (STR) is presented. The proposed TDC can virtually achieve as fine as desired time resolution by simply increasing its number of stages thanks to the STR unique features. Moreover, the proposed technique allows on-the-fly time measurement on fast non-periodic signals. The TDC has been implemented using 28 nm FDSOI technology to provide a proof of concept of the proposed method. Simulation results point out

Project: Importance of IR Drops on the Modeling of Laser-Induced Transient Faults

Authors: Raphael ANDREONI CAMPONOGARA VIERA (TIMA, CDSI), Philippe MAURINE (LIRMM, SYSMIC), Jean-Max DUTERTRE (ENSMSE, CMP), Rodrigo POSSAMAI-BASTOS (TIMA, CDSI)

Abstract: Laser fault injection attacks induce transient faults by locally generating transient currents capable of temporarily flip the outputs of several gates. Many models used to simulate transient faults induced by laser consider several elements to better represent the effects of the laser on ICs. However, a laser-induced current between VDD and GND, which provokes significant IR drops, has been neglected. This paper highlights the importance of the induced IR drops on the modeling of laserinduced transient faults by using IR drop CAD tools. It also shows that laser-induced IR drops can be sufficiently strong to produce alone transient faults. As a result, the number of faults on a case-study circuit is accentuated whether IR drop effects are taken into account.
