Yoshimura Lab 〜 Welcome to the world of optimization

NI Jianmo, 2nd Grade of Master’s program

Optimization technologies are widely studied in many fields. To researchers, the glamour of science is how to apply wonderful algorithms to solve the complicated problems in real world. Moreover, the development of creative algorithms is one of the most important driving forces for the social society. In Yoshimura lab, we have focused on the research of optimization technologies which are applied in the design automation of IC systems. Generally, IC system design includes Functional design, Logic design and Layout design. Because each of these design has difficult problems to solve and the scale of IC system is increasing year after year, IC system design becomes very difficult. Our target is to apply optimization technologies to design the highest performance IC system with the lowest cost within the shortest design time from both of theoretical and pratical points of view. Specifically, the reserches include the floorplan problem in physical level which focuses on how to decrease the chip size, the port assignment in high level design and the multiple voltage scheduling problem for power minimization, etc.

Every week, seminar is held within lab members and joint seminar with other labs is held as well. In seminar, students give a report on their recent research progress and result. Besides, the newest researches in corelated research field are introduced and discussed. After the report, professor always give us useful comment, the students make a heat discussion of the problem and exchanging questions with each other. During communications, it is possible for students to develop deep knowledge about the fundemental theories. Moreover, there might be creatice ideas come out.

Professor Yoshimura is very kind and always provide a strong support to students in a silent way. There are some cases if students have to contract him due to emergency, he will soon make a respondence even though it is late in mid night. Target at challenging the limit of performance by using optimization algorithms, all of the lab menmbers are trying their best in the world of optimization. If you have interest in the optimization technologies in the IC system design automation field, please go to our Yoshimura lab and have fun!
