Title:

Thermal simulation of 3D integrated circuits

Abstract:

Due to their compact structure, three-dimensional integrated circuits (3D ICs) present thermal dissipation issues. Integrated microchannels are emerging as a viable solution to dissipate the heat flux generated by 3D ICs. Several models have been proposed in literature to study different microchannel designs, but generally with low simulation performance. In this presentation, we present an efficient model to simulate the transient thermal behaviour of 3D ICs using microchannels. This work introduces a novel low-footprint model to deal with the complex geometry of 3D ICs. Additionally, we use advanced numerical methods to compute the transient temperature with linear time in the number of grid cells. Our approach is compared with state-of-the art models and reports a 100x speedup while maintaining the same level of accuracy.

Bio:

Gabriela Nicolescu is professor at École Polytechnique de Montréal. Since 1999, she has been involved in research on heterogeneous parallel systems. She published four books and one other are in production. She is the author of more than eighty articles in journals, international conferences and book chapters. In this field, she has numerous Canadian and international industrial and academic collaborations. Her research work explores long term solutions for STMicroelectronics, Mathworks, Canadian Aerospace. She is the co-founder of the Francophone Workshop on Heterogeneous Systems Design (FETCH) and she is actively involved in the organization of numerous international conferences (e.g. general chair for MPSoC 2011 and 2012. RSP 2010, FECTH 2007, executive committee member for DATE 2007, TPC member for DATE 2004-2013, program chair for RSP 2007 and MPSoC 2009, tutorial chair for NEWCAS 2006-2007 and special session chair for ASAP 2007, workshop chair for ISSS/CODES 2009-2012). She won the 2002 award for the best PhD dissertation at the Institut National Polytechnique de Grenoble, France and was co-author of best paper at ISSS/CODES 2004. In 2008, Prof. Nicolescu was in sabbatical at STMicroelectronics Canada Inc.
