Presentation
of the 2001 Phil Kaufman Award to
Professor Alberto Sangiovanni-Vincentelli
A. Richard Newton
But where do you start to describe his career, his impact
on EDA and on the lives of so many of us in academia and in industry, on his
many students, and business leaders throughout the world? Everyone I have spoken
to about Alberto believes they know him well, and yet they only really know a
fraction of this man who works so tirelessly in all of these areas of endeavor
and many more. Tonight I will take a few moments to describe to you the Alberto
I know, and will share the insights of a few key people who have had the chance
to walk beside Alberto for a part of this amazing journey.
Ill begin at the Politecnico di Milano, one of
the most distinguished universities in Italy, where Alberto graduated as a Dottore in Ingegneria (summa
cum laude) (Doctor of Engineering) in 1971 and served as Professore
Incaricato of Electrical Engineering from 1974-1976. At 27 years of age, he
was already making his mark as the youngest Associate Professor in the
University. I first met Alberto in 1975 when he and his young family came to
But Alberto was a system guy back then. Sparse matricies,
numerical analysis, linear placement for printed wiring boards, were his areas
of emphasis. He traveled in the circles of researchers like Ernie Kuh, Leon
Chua, and Charlie Desoer and knew very little about real circuits, let alone
integrated circuits, back then. It was in the late 1970s that he Alberto
caught Don Pedersons eye.
I first
became acquainted with Alberto when he was a young Assistant Professor in EECS,
says Professor Don Pederson, himself a Kaufmann winner. Alberto was eligible
for a permanent position in Circuit and Systems Theory Groups in this county, as
well as in his home country,

academic career is unparalled. With over 500 technical publications to his name
and fourteen booksspanning the areas of EDA, control theory, systems theory,
and applied mathematics just to name a fewAlberto has educated and mentored a
generation of distinguished university faculty and industry leaders. Among his
many awards, he includes the Distinguished Teaching Award of the

students and now a distinguished faculty member at MIT was working on the new
Waveform Relaxation (WR) method while Professor Res Saleh, one of my own
students, was working on what we called Iterated Timing Analysis (ITA)two
accurate but fast methods for simulating large digital circuits. Alberto had
been giving talks about WR in which he claimed that WR had guaranteed
convergence properties while ITA did not. As Jacob says, I tried to convince
Alberto that once you discretized the differential equations, WR had the same
convergence properties as ITA. Alberto was very patient with meat the time I
was not doing very well as a studentand he had every reason to believe that I
was simply confused. However, the very second that my argument was clear to him,
Alberto changed from being a patient listener to an enthusiastic one. The fact
that I was suggesting that what he had been presenting was wrong did not concern
him at all. He was interested in only two things: getting the right answer and
expressing his pleasure that one of his students had figured out something that
he had missed.
Of
course, Jacob continues, this incident demonstrated to me that being the
one who is right is unimportant, while getting to the right answer is important.
But for me, the idea that my advisor would be pleased that I had uncovered an
error really helped me understand what it means to be an academic. The job is
not about leading your students, the
job is about having students stand on your shoulders and see further than you
did. That is one of the most important lessons I learned from Alberto.
This is just
one of many such experiences I could quote from any one of the more than 50
Ph.D. students Alberto has guided to graduation over the past quarter
centuryanother amazing achievement.
As Gerry
Sullivan once shared with me as we walked along a stretch of beach near
No
matter what Alberto tackles, he succeeds in making an impressive set of
contributions, says Professor Bob Brayton of IBM Research and now Berkeley.
Our logic synthesis collaboration was marked by lots of excitement,
enthusiasm and fun. It was fun, since we shared the common conviction that a
firm mathematical foundation and proven results leads to better understanding
and to better algorithms. At DAC in '82, I remember sitting on a couch in the
lobby of the Las Vegas Hilton, working with Alberto on the remaining algorithmic
piece of the two-level logic optimizer ESPRESSO. When we finally got it, we were
so excitedit was far better than winning at the casino!
In 1981,
Alberto joined Jim Solomon, then at National Semiconductor, and me as we sought
for ways to get some of our early Berkeley CAD tools and ideas supported by
industry. After six months of talking with companies like Daisy Systems, Mentor
Graphics, Comsat General, Valid Logic Systems, and even the Microelectronics and
Computer Consortium (MCC) in Austin Texas, and finding no takers, Jim decided to
start a company to support and develop our ideas for commercial use as SDA
Systems and eventually Cadence Design Systems.
Ill leave it to Joe Costello, former CEO of Cadence to
describe Albertos influence on that company from the very beginning:
Alberto helped to shape Cadence (then SDA Systems) long before I was there.
He sent his students, worked the strategy, and guided the product. He agonized
when the company struggled to get off the ground. He talked to customers to get
them to work with us. He criticized, counseled, consoled. He tried to get us to
think big when we were small. He tried to get us to work with an even smaller
company, Synopsys, as it was born, but we didn't understand. He supported our
moves to merge with ECAD, Tangent, Gateway when others didn't agree. He was a
scientific advisor and a consultant. He worked with our engineering team year
after year, inspiring them, challenging them, spurring them on. He provided
insights into where we should go and who could best take us there. He pushed and
pushed and pushed to make us great. He personally created Cadence Berkeley Labs
with Patrick Scaglia. He established it in the
As I re-read these words, they look so pathetic when I
stand them up against reality. Words are such a weak tool to encapsulate what
Alberto has meant to me personally and to Cadence. I wish that I could share
with you a video kaleidoscope of the times that we have spent together. It would
better capture some of the energy, passion, and emotion. You would better
understand the highs, the lows and the ultimate victory. But still when I run
the video in my mind and stand it up against reality, it is also too narrow, too
thin, if you weren't there to see it as it unfolded.
How can I help you to understand Alberto's contribution?
Perhaps, since you weren't there, a symbol would be best. When you think of
Cadence, remember that the a in Cadence stands for Albertowithout the
"a", without Alberto, the company would just not be the same.
Ray Bingham
summarizes Albertos ongoing contributions to Cadence as follows: Alberto
has had a profound and lasting influence on Cadence as a company and on me
personally as an individual. As Cadences Chief Technology Advisory, Alberto
provides boundless intellectual capacity and bandwidth, which I leverage when
considering various business, technology, strategic, and political issues. In
other words, he's my ultimate reality check.
Now one of
those companies that Joe mentioned was Tangent, and Aki Fujimura, now President
and COO of Simplex Solutions was a founder of Tangent. Aki recalls that:
Steve Teig and I both benefited tremendously from Alberto's insights and
guidance while we were rolling out Tangate fourteen years ago. Alberto was
instrumental in evangelizing the shift from a channels-and-rows based
semi-custom architecture to the sea-of-gates/sea-of-cells architecture that the
whole world uses today. Alberto's greatest strength is his unique blend of
technical breadth and depth, his intuition for people, and his business
savvy.
Just a few
years later, Alberto was also a key contributor to the founding team of Synopsys
and was the founding chair of the Synopsys Technical Advisory Board. As Aart De
Geus says, "Alberto has the amazing talent and drive to simultaneously
recognize break-through technology, talented people, and a business opportunity.
So often he has acted as a powerful catalyst in amplifying the work of the
people around him. I will always be grateful for his contribution in starting
the most exciting EDA company of all timewhichever one you happen to think it
is..."
Albertos
Ph. D. students, in particular Rick Rudell and Albert Wang, formed a core part
of the product team for Design Compiler, the most successful single product in
the history of the EDA industry to date, and Design Compiler was influenced very
strongly by the Berkeley work of Bob Brayton, Alberto, and their students in the
area of multi-level logic synthesis.
In 1991,
Cadence and Synopsys had grown to the point where they were beginning to compete
in the marketplace and Alberto was forced to make a choice. I can personally
attest to the fact that this was one of the most difficult choices Alberto has
ever had to make. He agonized long and hard on it and, frankly, at the time he
could have gone either way. My third insight into the man: over the years I have
learned that Alberto likes to be involved in just about everything. For two
reasons: first he, like many of us, has a very hard time saying no to
people he likes and respects. Second, when Alberto makes a commitment, you can
always count on him to see it through, no matter what it takes, and he found
himself in a situation where he had personally committed his energy to both
teamsteams that were now in an irreconcilable conflict for him. I know those
were some of the toughest days for Alberto as he worked through that situation.
To this day, I know he has a strong love for both companies.
Of all the
contributions Alberto has made to our industry, the two that he is personally
most proud of are his work in guided analog synthesisdefining a new approach
to the automated design of analog IC blocks, through the Red Book as he
likes to call itand his work on system-level design. While Alberto has
collaborated closely with many of the leading researchers in EDA and control
systems over the years, in these two areas he has truly paved the way for us
all. He really began by advocating system-level design research in earnest back
in 1988, stressing the importance of a comprehensive view of systemsnot just
the chips, the importance of software and hardware, that the methodology was key
to finding a common ground for effective system design, and that one had to
study embedded systems and their application in the real world if one was to
find a rigorous, well-founded and yet practical approach to the design and
verification of complex embedded systems. Who among us had not heard of
communication-based design, or the importance of orthogonalization of
concerns, or function-architecture decomposition? These are just a few
of the concepts Alberto has developed and evangelized for years now, and all are
finding their rightful place in our modern design systems.
But like all
of our Kaufman awardees, and like Phil himself, in the end it is as much the
person as it is about any specific technical contribution or new business
ideait is how they have inspired people throughout their careers, through
their own personal example. As Aki Fujimura said,
What makes
Alberto great is that whether you're meeting him for business or for academic
advice, the first thing he wants to talk about with you is... you. We all know
that he genuinely cares about us as individuals and that this comes first before
anything else for him. Ray Bingham told me earlier this week that,
Albertos deep humanity as a person...as a man...exudes itself in
everything he does. That humanity gives him license to inspire and touch people
in many ways. He certainly has played an inspiring role in my own life. And our
industry is extremely fortunate to call him one of our own. I would also like
to take this opportunity to thank Alberto for his steadfast friendship and
support over these many years, through the mostly good times and the occasional
tough passage. On behalf of your many, many friends throughout the world, thank
you, Alberto.
On behalf of Mrs. Kaufman, EDAC, and all present here
tonight, I am honored to be able to present the Phil Kaufman Award to Professor
Alberto Sangiovanni-Vincentelli, a colleague, a mentor, and a friend to many of
us here tonight and around the world. As I wrote this speech, I tried to
conclude by summarizing what makes Alberto specialwhat are those essential
characteristics of this man that make him so important to us allbut I found
that I just couldnt do it. I share Joe Costellos perspective when he says
that words are such a weak tool to encapsulate what Alberto has meant to us all.
So I leave you with these few anecdotes and testimonials of the many we could
all share about this founder of our industry and leave it to you to build your
own picture of Alberto and his many contributions. But I know you all agree with
me when I say it is clear that Alberto stands as a very worthy recipient of this
prestigious award.
So please raise your glasses as we toast Alberto tonight. Professor Kurt Keutzer speaks for all of us when he says, Through his technical efforts Alberto has done much to define what EDA is today, but much more than that, Alberto has set the highest standard for what it means to be a researcher in this field.
To Alberto!
