About me

I am currently a Ph.D. candidate at the School of Microelectronics, State Key Laboratory of Integrated Chips and System, Fudan University, Shanghai, China, under the supervision of Prof. Xuan Zeng & Prof. Fan Yang. Prior to this, I earned my B.S. and M.S. from Ningbo University in 2019 and 2023, respectively, working with Prof. Zhufei Chu. I have been recognized with several academic honors, including the Best Paper Award at the CCFDAC'21, an Honorable Mention Paper at the ISEDA'24, and the first place in the MLCAD'25 contest. Additionally, I am actively involved in maintaining the logic synthesis framework phyLS. My research interests span various aspects of logic synthesis, its practical applications, and the integration of machine learning techniques in EDA and CAD for emerging technologies.

Tools

phyLS: powerful heightened yielded Logic Synthesis. [GitHub]

phySAT: Semi-Tenser Product based SAT and AllSAT solver, where it can solve CNF and circuit input. [GitHub]
