Acknowledgments
Authors would like to thank our colleagues and friends at McGill University, Agere
Systems/LSI Corporation and Texas Instruments for providing a good environ-
ment to conduct this research and finish the book. We especially thank Dr. Yi Cai
at LSI for providing longstanding and wise technical advice and co-authoring two
papers, Professor Gordon Roberts at McGill for giving research guidelines, Bill
Kempler and Sam Yingsheng Tung at Texas Instruments for reviewing the manu-
script. A part of the work leading to this book was undertaken while Yongquan
Fan was pursuing first his M. Eng. and then Ph. D. degree at McGill University.
Our thanks also go to Liming Fang, Anant Verma, Bill Burchanowski, and San-
deep Kumar for collaborating on a work that led to co-authoring one paper. We
also appreciate the technical support and help from the whole PHY and Storage
team at Agere/LSI, especially from Angshu Bhattacharyya, Joe Martone, John
Janney, Suri Basharapandiyan, Bernhard Laschinsky, Kevin Richter,P aulH ua,T om
Gibson, Kahn Neguen, Bo b Hain and Ken Paist.
In addition, we thank the many people who have given valuable advice, feed-
back and help at conferences and various other occasions. Special thanks are ex-
tended to Mohamed Hafed at DFT Microsystems, Takahiro J. Yamaguchi at Ad-
vantest Corporation, Yang Liang at Maxim, Steve Sunter at Logic Vision, Mike Li
at Wavecrest (now at Altera), Xu Fang at Teradyne, Joe Venable, Shu Xia and
Wai Lee at Texas Instruments, Jwo Cheng and Carlo DiGiovanni from GigOptix,
Minh Tran from Teledyne, Mani Soma at University of Washington, Luo He at
Concordia University, Warren Gross, Kasia Radecka, Atanu Chattopadhyay,
Man-Wah Chiang, Rong Zhang, Milos Prokic and Jean-Samuel Chenard at McGill
University
Altera Corporation has provided also a great support throughout the years, from
their devices and intellectual property, to the encouragement and research funding.
Special thanks go to Steve Brown, Fort Blair, Tomasz Czajkowski and David
Mendel.
At Springer Science+Business Media, Mark de Jongh and Cindy Zitter were
always there for us, providing encouragement and cheering the race to the finish
line.
As with the recent book (Generating Hardware Assertion Checkers, Springer
2008) co-written by Marc Boulé and Zeljko Zilic, the cover page art was drawn by
the second author’s children. This time, Maria Zilic took artistic leadership, with

Ivan and Pauline Zilic doing their share to together depict the effects of the jittery
clock in an appealing and a surprisingly lucid way.
Last but not least, we would like to thank our whole families for their love and
support over the years. Without their support, it would be impossible to undertake
all the work and finally write the book.
