European Design and Automation
EDAA Lifetime Achievement Award Recipient of 2006
EDAA Lifetime Achievement Award 2006
for Professor Robert K. Brayton,
University of California at Berkeley
Every year, the European Design Automation Association, EDAA, main sponsor of the DATE event (www.edaa.com), honors an individual who made outstanding contributions to the state of the art in electronic design, electronic design automation and test of electronic systems in his or her career.
This time, the jury has selected Robert
Brayton received a BSEE degree from
In his work at IBM he made fundamental contributions to three key areas of design automation, circuit modeling, simulation, and synthesis. His paper describing the Brayton-Moser function to model non-linear circuits published in 1964 is still considered a centennial paper in that area. With his profound mathematical background, he was instrumental in the development of circuit simulation as it is today. As Jochen Jess, professor at the TU Eindhoven, The Netherlands, and last year’s laureate, states: “He was the main inspirer of the IBM group (comprising Hachtel, Liniger, Willoughby and Gustavson) that pioneered all essential features of modern circuit simulation: modeling of nonlinear circuits, sparse matrix handling (only preceded by Tinney and Walker in the late 50's), variability analysis of the Jacobian, dynamic step size control under discrete integration - all essential to handle large strongly nonlinear circuits. Almost all other work in that area owes to those results although SPICE is so much more popular.” At IBM, he also developed methods for the efficient calculation of partial derivatives and sensitivities that are still in use for optimization in modeling.
Even more impact
had his groundbreaking work in logic synthesis. Again Jochen Jess: “The
scripts of ESPRESSO were developed at IBM under his guidance. Also,
logic synthesis was first effectively mechanized as the "YLE", the
"Yorktown Logic Editor" written in APL, then later transferred to
With Robert Brayton, the EDAA honors one of the main pioneers and intellectual fathers of design automation both as a science and as an industry.
