EDITORIAL

You are cordially invited to participate in the next ReSMiQ Innovation Day on October 12, 2017, at Polytechnique Montréal. This activity, organized by our center, aims to provide visibility to the research work of students from Quebec in the field of microsystems among the members of the scientific community Québec. The call for projects announced across the province of Québec has resulted in the selection of a total of 16 projects, 2 from undergraduate students and 14 from graduate students.

The candidates for the competition will demonstrate their scientific and technical expertise to a panel of judges composed of many experts. The best 3 projects in both categories will receive a cash award. RID 2017 will also be an excellent opportunity to attend keynote presentations by two renowned speakers such as Jose M. de la Rosa from the Universidad de Sevilla and Hao Yu from the Southern University of Science and Technology in Shenzhen in China. We thank all of the students who submitted their project. We invite you to visit our web site (www.resmiqinnove.ca) for more details.

ReSMiQ is a group of researchers in an interuniversity research center that can count on the support of the Fonds de recherche du Québec – Nature et technologies (FRQNT) and nine (9) Quebec universities involved in microsystems research.

Transient Thermal Simulation of Liquid-Cooled 3-D Circuits

The 3-D integrated circuits (3-D ICs) are emerging as a viable solution to enhance the performance of many-core platforms. These architectures generate a high and rapidly changing thermal flux that makes conventional air-cooled devices more susceptible to overheating. Liquid cooling is an alternative that can improve dissipation and reduce thermal issues. Fast and accurate thermal models are needed to appropriately dimension the cooling system at design time. Several models have been proposed to study different designs, but generally with low simulation performance. In this paper, we present an efficient model of the transient thermal behavior of liquid-cooled 3-D ICs. This paper presents an approach with extremely low memory usage and advanced numerical methods to efficiently compute the transient temperature of 3-D ICs. Our experiments show the 100x speedup versus the state-of-the-art models, while maintaining the same level of accuracy, and demonstrate the efficiency of liquid cooling to remove the heat from 3-D many-core platforms.
