In recent days, ,2022 International Computer Society of the year （ACM） Student research competition (SRC) The winners of the global finals were officially announced ！ among , come from Guozizheng of the Turing class of Peking University （EDA） Contributions in the field , Won the first place in the undergraduate group in the world （First Place）.

After the official wechat of Peking University announced the good news , The xinhua news agency 、 People's daily and other state-owned media have praised and forwarded , At that time , The name "senior minister Guo" has attracted a lot of attention .

A coincidence , Confirmed by guozizheng EDA Research direction

According to the official wechat of Peking University , Guozizheng is a senior student in Turing class of information science and Technology College of Peking University . Turing class as a Peking University in 2017 The experimental class established in , It has gathered the best computer undergraduates in China , We are committed to training top-notch talents in the field of computer science .

Back in high school , Senior Minister Guo won the gold medal in the national informatics competition , This also made him qualified for admission to Peking University . 

With great enthusiasm for scientific research , The scientific research rotation activity held by the cutting-edge Computing Center opened the scientific research road of senior minister Guo . At that time, senior minister Guo, a sophomore, could choose to enter the research groups of three different teachers to experience scientific research life , He was the first one to join the research group of Professor linyibo of the Institute of integrated circuits .

Coincidentally , Teacher linyibo's research direction at that time was the automation of chip design based on machine learning （EDA） Algorithm and GPU/FPGA Speed up . 

In recent years , Yes “ The mother of chips ” It's called. EDA It has always been a domestic chip “ thetime ” The key link .“ Who knows EDA, Who has the leading power in the chip field ”, It has almost become the consensus in the industry .

When it comes to why we choose scientific research , Why choose EDA Direction , Senior Minister Guo gave two reasons ：

• One is right EDA More interested in the direction ,“ First of all, it fits the experience of some algorithm competitions before , Secondly, the process of getting started by oneself is also relatively smooth .”;

• The second is to respond to the call of the state , Solve the technical problems required by National Development .

A publication 8 Top papers , Committed to tackling key problems “ thetime ” technology

In scientific research , Guozizheng's main research direction is EDA In the field of static timing analysis . As a key step in chip design , It aims to determine the design correctness and maximum operating speed of the chip , It requires high accuracy 、 Time consuming 、 Features that span the entire design process .

According to guozizheng's personal homepage , Its presence 2020 - 2022 During the year, a total of 11 Papers , Among them, those published in the capacity of one work are 8 piece , All EDA International top academic conferences and journals in the field DAC、ICCAD、TCAD Waiting to receive .

The paper that won the first place in the final , be known as ：Heterogeneous Timing Estimation,Optimization,and Verification for VLSI Circuit Design Automation（ be used for VLSI Heterogeneous timing estimation for circuit design automation 、 Optimization and validation ）, Also included in ICCAD 2021 in .

In the above paper , Including the use of... First proposed by senior minister Guo GPU An algorithm for accelerating static timing analysis , And the first realization of linear spatiotemporal complexity 、 Path analysis algorithm with 100 times efficiency improvement .

In addition to the field of chip static timing analysis , Senior Minister Guo is still EDA Artificial intelligence is introduced in . He combines graph neural network with timing analysis engine , This paper presents a modeling technique that spans many aspects of the chip design process , The custom graph learning method simulates the parsing process of time series analysis . At the same time, he also explored the analogy between time series analysis process and neural network training , The first layout optimization algorithm based on differentiable timing engine is proposed , Compared with the most advanced layout algorithm, the performance is improved 28% above .

Guozizheng pays attention to the combination of scientific research process and production practice , Besides publishing papers , He also applied for five patents for his invention , Some of these patents have been authorized .

During the undergraduate period , As a member of Peking University supercomputing team , Senior Minister Guo has participated in competitions with the team for many times , And won the world university supercomputing competition （ASC） The first prize , International Undergraduate Program Design Competition （ICPC） Regional champion , Get... Many times ICPC/CCPC Gold medal in college students' program design competition, etc . Based on his excellent academic performance , Senior Minister Guo also won the highest honor of Peking University Students at the 13th “ Student five · Four medals ”

Senior Minister Guo will stay at Peking University after graduation , Enter the Institute of integrated circuits to study for a doctor's degree , Continue his study and research in this field .

Last , Once again, I congratulate senior minister Guo on winning this honor , I also wish him to be able to tackle key problems EDA“ thetime ” Make more achievements in technology ！
