PKU undergraduate just won the first place (undergraduate group) in the finals of the annual student scientific research competition of the international society of computers (ACM) by virtue of their contributions in the field of chips, and also received praise from the people's daily. The young man, named guozizheng, is a senior student of Turing class of Peking University. He has now directly entered the school of integrated circuits of Peking University.
It is not the first time in his research / competition resume that he won the prize in this competition. Previously, as a member of the supercomputing team of Peking University, he won the first prize of ASC in the world university supercomputing competition. He also published 8 papers on international conferences in the field of chip design automation (EDA), such as DAC, ICCAD, date, etc.

Under the official wechat, many netizens praised and congratulated it one after another.
Published 8 top conference papers as a writer
The Turing class of Peking University is a class specially established by Peking University to cultivate top-notch talents in the field of computer science. Each student is selected from thousands of freshmen. As a member of the Turing class, senior minister Guo had the opportunity to enter various research groups to experience scientific research life in his sophomore year.
According to the official wechat of Peking University, his fate with EDA began with the scientific research rotation activity held by the cutting-edge computing center.
As a sophomore at that time, he was the first to choose the research group of researcher linyibo of the Institute of integrated circuits. Lin Yibo's research direction is EDA and GPU / FPGA acceleration of EDA algorithm.
There is no need to repeat the importance of EDA, which is also called chip design automation, and is one of the key technologies of "bottleneck" in China. Many media commented that "Whoever has mastered EDA will have the dominant power in the chip field."
Guozizheng's main research direction is the field of static time series analysis in EDA. As an important step in chip design, it is a workflow to calculate and predict the timing of digital circuits. Simulation is not required in the workflow.
According to his homepage, the undergraduate has published a total of 11 papers from 2020 to 2022, including 8 as one work, which have been accepted by international top academic conferences and journals DAC, ICCAD, TCAD, etc. in the EDA field.
This includes the proposed algorithm of using GPU to accelerate static timing analysis, and the first path analysis algorithm with linear space-time complexity and efficiency improvement of 100 times.
This award-winning paper, called heterogeneous timing estimation, optimization, and verification for VLSI circuit design automation, is included in ICCAD 2021.
In addition, he also integrated artificial intelligence.
For example, the graph neural network and timing analysis engine are combined to propose a modeling technology that spans multiple links of the chip design process.
Also, inspired by deep neural network, a layout optimization algorithm based on differentiable timing engine is proposed, which is said to be the first time in the academic circle.
The optimized layout framework can achieve up to 32.7% and 59.1% improvement on WNS and TNS respectively, and achieve 1.80 times acceleration when running on GPU.
Based on this academic performance, he won the 13th May 4th student medal, the highest honor of Peking University.
After graduation, he will continue to stay in the University and study for a doctor's degree in the Institute of integrated circuits.
Talking about the choice of EDA direction, senior minister Guo said that on the one hand, it is the need of the country. Respond to the call of the state and solve the technical problems required by the national development. On the other hand, it is also interest driven, which has something to do with the previous competition experience.
First of all, it fits the experience of some algorithm competitions before. Secondly, the process of getting started is also relatively smooth.
In fact, in his middle school days, senior minister Guo had already participated in the information science competition, and thus obtained the admission qualification of Peking University.
His bzoj submitted records in this way.
After entering Peking University, he and his teammates won the champion of ICPC regional competition in 2019 International College Students' programming competition, the first prize of ASC in the world college students' supercomputing competition, and ACM SRC@ICCAD The student won the first place in the undergraduate group of the student scientific research competition, and won the gold award of ICPC / CCPC undergraduate program design competition and other honors for many times.
Five of the six winners are Chinese
It is worth mentioning that in addition to senior minister Guo, four of the six winners of this year's SRC global finals are also Chinese faces.
include:
Laiziliang, a doctoral student of the Chinese University of Hong Kong, won an award for his research on deterministic concurrency control of blockchain.
Haotian Zhang, Ph.D. candidate of the University of Texas at Arlington, won the award for research on MIPs.
Zhang Yihong is currently studying for a master's degree at the University of Washington. Her research interests are mainly in the theory and application of programming languages and database systems.
Chen Yang, an undergraduate of Tianjin University, is entitled accelerating redundancy based program repair via code representation learning and adaptive patch filtering.
In addition, senior minister Guo won the first place last year SRC@ICCAD In the student research competition, Chinese universities have also gained a lot.
For example, Yu Qian, an undergraduate of Zhejiang University, won the third place in the undergraduate group by virtue of his research on content addressed memory.
Xiaofan Zhang, the first in the graduate group, graduated from the University of Electronic Science and technology with a master's degree and is currently studying for a doctor at the University of Illinois at Urbana Champaign.
Qi sun, the third in the graduate group, is from the Chinese University of Hong Kong. He graduated from Xi'an University of Electronic Science and technology.
It can be said that this is also an epitome of the frequent emergence of Chinese universities and Chinese students in the world EDA competition in recent years.
Last year, Huazhong University of science and technology won the first prize in the ICCAD competition of the international summit conference in the field of EDA. The topic of china team winning the EDA global champion .
From 2017 to 2019, Fuzhou University won three consecutive titles in this event.
Among the 30 winners of the ICCAD algorithm competition, 11 went to the Chinese University of Hong Kong.
It should be acknowledged that in the EDA field, China is still facing the dilemma of "bottleneck". However, on the academic military training ground, the light of reserve forces is also becoming more and more shining.
