Tutorial I

Title:

Beyond DFT: The Convergence of DFM, Variability, Yield, Test, Diagnosis and Reliability

Presenters:

Dr. Srikanth Venkataraman
Principal Engineer at Intel Corporation

 

Dr. Robert C. Aitken
IEEE Fellow, ARM Inc

Abstract:
The tutorial goal is to show how design for yield (DFY) and design for manufacturability (DFM) are tightly coupled into what we conventionally think of as test. As process geometries shrink, the line between defects and process variation blurs to the point where it is essentially non-existent. As feature sizes reduced, systematic mechanism-limited yield loss began to appear as a substantial component in yield loss due to the interaction between design and manufacturing. The basics of yield and what fabs do to improve defectivity and manage yield are described. DFM techniques to analyze the design content, flag areas of design that could limit yield, and make changes to improve yield are discussed. In DFM/DFY circles, it is common to speak of defect limited yield, but it is less common to think of test-limited yield, yet this concept is common in DFT (e.g. IDDQ testing, delay testing). Test techniques to close the loop by crafting test patterns to expose the defect prone feature and circuit marginality through ATPG, and by analyzing silicon failures through diagnosis to determine the features that are actually causing yield loss and their relative impact are covered. This tutorial will provide background needed for DFT practitioners to understand DFM and DFY, and see how their work relates to it. The ultimate goal is to spur attendees to conducting their own research in the area, and to apply these concepts in their jobs.

 Tutorial II

Title:

Power-Aware Testing in the Era of IoT

Presenters:

Dr. Patrick Girard,
CNRS Research Director in the Microelectronics Department of LIRMM

 

Prof. Nicola Nicolici
Dept. of Electrical and Computer Engineering, McMaster University

 

Prof. Xiaoqing Wen

Abstract:
Managing power consumption of circuits and systems is one of the most important challenges for the semiconductor industry in the era of IoT. Power management techniques are used today to control the power dissipation during 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. Its first part gives the background and discusses power issues during test. The second part provides comprehensive information on structural and algorithmic solutions for alleviating test-power-related problems. The third part outlines low-power design techniques and shows how low-power devices can be tested safely without affecting yield and reliability.
