technology nodes at 32 nm and below, power supply noise is a major contributor to the degradation of circuit performance. This article presents an overview of low-power testing and delay test techniques; in addition, the article surveys ongoing research activities in academia and industry for analyzing power supply noise and dealing with its effects during delay test and timing analysis.
A special perspectives article on the past, present, and future of electronic design automation (EDA) is also included in this issue. This article is in the form of a reportÀ À''NSF Workshop on EDA: Past, Present, and Future (Part 1)''À Àwhich is based on a National Science Foundation workshop on this topic held in July 2009. The document is both restrospective and forward-looking, and it should especially appeal to the Design & Test readership. Jason Cong and Robert Brayton have prepared the report in two parts, and the first part is being published in this issue. You can look forward to Part 2 of this report in the May/June issue.
Elsewhere in this issue, we have included a onepage report summary of highlights from both HLDVT 2009 and part 2 of the ITC 2009 panel summaries. For the full versions of reports and panel summaries, see http://www.computer.org/dt/conf_reports and http://www.computer.org/dt/panel_summaries. Readers will also find our regular Book Reviews and The Last Byte departments. Grant Martin reviews the recently published Embedded System Design: Modeling, Synthesis and Verification by Daniel D. Gajski, Samar Abdi, Andreas Gerstlauer, and Gunar Schirner. This book is a timely introduction to embeddedsystems design methodologies and tools. In The Last Byte, Sani Nassif takes a swipe at the complexity of today's models for ICs and makes an eloquent case for simplicity in modeling and analysis.
In forthcoming issues, D&T will publish columns by Andrew Kahng ( The Road Ahead), and an update from Jeff Rearick on IEEE standards activities in design and test. We have also started a new Tutorials department, under the leadership of Dimitris Gizopoulos, and we plan to publish two tutorial articles in 2010.
