Prof. S. Ramprasath
Assistant Professor, Electrical Engineering, IIT Madras

He is an Assistant Professor in the Integrated Circuits and Systems Group of the Department of Electrical Engineering, IIT Madras. His primary research interests are in Electronic Design Automation (EDA) Algorithms, with a specific focus on automating the Back End of Line (BEOL) flow for custom digital and analog/mixed-signal (AMS) designs.

...  more

He was involved in the development of the AMS placer and router in ALIGN, an open-source layout generator. During his stint at Synopsys after completing his PhD, he developed various tools for BEOL automation that are now state-of-the-art and are part of the Custom Compiler platform.

His recent research interests include mapping NP-hard/complete problems to Ising machines and exploring techniques such as Satisfiability Modulo Theory (SMT) for solving layout generation problems.
