Title: Power-Aware Testing in the Era of IoT
Speaker 1: Prof. Xiaoqing Wen, Kyushu Institute of Technology, Department of CSE
Speaker 2: Dr. Patrick Girard, LIRMM / CNRS
Date: Monday, 27 Nov., 2017
Managing the power consumption of circuits and systems has become one of the most important challenges for the semiconductor industry, especially in the era of IoT. Sophisticated power management techniques, such as voltage scaling, clock gating, power gating, etc., are widely used today to control the power dissipation during the functional operation. Since the application of these techniques has profound implications on manufacturing test, power-aware testing has become indispensable for low-power LSIs and IoT devices. This tutorial provides a comprehensive and practical coverage of power-aware testing, with the following three parts. The first part gives the background and discusses various problems arising from excessive power dissipation during scan testing. The second part provides comprehensive information on structural and algorithmic solutions for alleviating the test-power-related problems. The third part outlines low power design techniques and shows how these low power devices can be tested safely without affecting yield and reliability. Biography:

Title: Data-Driven Resiliency Solutions for Integrated Circuits and Systems
Speaker: Prof. Krishnendu Chakrabarty, Department of Electrical and Computer Engineering, Duke University
Date: Monday, 27 Nov., 2017
Design-time solutions and guard-bands for resilience are no longer sufficient for integrated circuits and electronic systems. This tutorial will describe how data analytics and real-time monitoring can be used to ensure that integrated circuits, board, and systems operate as intended. The speaker will first present a representative critical path (RCP) selection method based on machine learning and linear algebra that allows us to measure the delay of a small set of paths and infer the delay of a much larger pool of paths. In the second part of the talk, the speaker will focus on the resilience problem for boards and systems; we are seeing a significant gap today between working silicon and a working board/system, which is reflected in failures at the board and system level that cannot be duplicated at the component level. The speaker will describe how machine learning, statistical techniques, and information-theoretic analysis can be used to close the gap between working silicon and a working system. Finally, the presenter will describe how time-series analysis can be used to detect anomalies in complex core router systems. Biography:
