Subhasish Mitra, Associate Professor of Electrical Engineering and of Computer Science, has received the Semiconductor Research Corporation (SRC) Technical Excellence Award for his research related to Quick Error Detection (QED) technology.
Electronic systems are an indispensable part of all our lives. Malfunctions in these systems have consequences ranging from annoying computer crashes, loss of data and services, to financial and productivity losses, or even loss of human life. To ensure robust operation of electronic systems, it is essential to minimize the effects of design flaws (bugs) in the hardware. Unfortunately, existing test and validation methods cannot cope with the tremendous complexity of today's integrated circuits and systems. As a result, many critical bugs are detected only after integrated circuits (ICs) are manufactured. During post-silicon validation and debug, manufactured ICs are tested in actual system environments to detect and fix bugs in hardware. Existing post-silicon validation and debug techniques are ad hoc and very expensive, and their cost and complexity are rising faster than design cost.
Quick Error Detection (QED) technology overcomes post-silicon validation and debug challenges by detecting bugs a billion times quicker compared to existing approaches, while simultaneously catching critical bugs that would otherwise go undetected and severely jeopardize robust operation of electronic systems. QED also localizes difficult hardware bugs automatically in only a few hours so that the detected bugs can be fixed efficiently. In contrast, it might take days or weeks (or even months) of manual work (per bug) using existing approaches. QED has been successfully used in industry.
"I am honored by this award from the SRC in recognition of the QED technology," replied Professor Mitra. "QED is key to ensuring robust operation of electronic systems we rely on everyday. My sincere thanks to the SRC for funding my research, and for selecting the QED technology for this prestigious award. I am fortunate to work with an excellent group of highly-motivated undergraduate and graduate students at Stanford, as well as fantastic collaborators from industry and academia. The QED technology would have been impossible without them. Finally, I also thank the NSF since the roots of this QED work started with support by the NSF CAREER award."
- The students that contributed to this QED technology are: David Lin (EE '15), Dr. Yanjing Li (EE '13), Dr. Sung-Boem Park (EE '10), Ted Hong (MS '07), Diana Mui (MS '11), Ziyad Abdel Khaleq (MS '12), Sundaram Ananthanarayanan (MS '14), Eshan Singh (PhD candidate), Christine Cheng (MS), and Dr. Farzan Fallah.
