Nanjing, China – A Chinese chip design research team has garnered international recognition at a leading academic conference. Recently, the LAMDA (Learning and Mining for Data Analysis) Group, led by Professor Qian Chao from the School of Artificial Intelligence at Nanjing University, received the Best Paper Award at DATE 2025 (Design Automation and Test in Europe) for their paper titled Timing-Driven Global Placement by Efficient Critical Path Extraction.
The DATE conference, jointly organized by the prestigious IEEE (Institute of Electrical and Electronics Engineers) and ACM (Association for Computing Machinery), is a premier international academic gathering in the field of Electronic Design Automation (EDA). It attracts researchers and experts from around the globe.
The award-winning paper presents a novel approach to timing-driven global placement, a critical step in the chip design process. The research focuses on efficiently extracting critical paths to optimize the placement of components on a chip, ultimately leading to improved performance and efficiency.
The research was a collaborative effort between Nanjing University and Huawei Noah’s Ark Lab. The first author of the paper is Shi Yunqi, a master’s student at the School of Artificial Intelligence, Nanjing University. Lin Xi, an undergraduate student, and Xue Ke, a doctoral student, also from the same school, are the fourth and fifth authors, respectively. Professor Qian Chao served as the corresponding author.
