Semiconductor Design Automation Lab.

The Semiconductor Design Automation (SeDA) lab. is in the Dept. of Electrical Engineering at Ulsan National Institute of Science and Technology (UNIST).

SeDA lab. focuses on researching and developing computer-aided design (CAD) solutions for SoC & VLSI. Our goal is to build electronic design automation (EDA) frameworks for cutting-edge digital IPs/chips with short time-to-market (TTM) and optimized power, performance, area, and cost (PPAC). We are extending our research coverage in the direction of (1) next-generation integrated chip (IC) structures, such as 3D ICs, chiplet-based 2.5D ICs, and under advanced technology nodes; and (2) EDA with AI in both directions: AI for EDA (AI/ML application to EDA) and EDA for AI (EDA framework for AI chip design)

We welcome good-natured and self-motivated students to join us as Post-doctoral researchers, graduate students, and undergraduate interns, and enjoy a fun graduate school life with interesting research topics! (Click here.)
