He has been working on modeling and measurement of on-chip power supply noise and signal coupling noise. Professor Hashimoto's research interests include timing, power, and signal integrity analysis, ultra-low power design, design for reliability, performance optimization in physical design, and on-chip high-speed signaling. He has co-authored several journal articles. Raj Nair, a consultant in IC power delivery and power integrity, is co-founder of Anasim Corporation, which commercializes power integrity and energy aware SoC (System on Chip) design tools.
