About Me
I'm a Senior Physical Design Engineer at Samsung Semiconductor India Research (SSIR), where I work on the physical implementation of complex ASIC designs. Starting from a synthesized gate-level netlist, I take designs through the complete implementation flow to GDSII, focusing on building high-performance, power-efficient, and manufacturable chips.
My work involves quality netlist generation, floorplanning, placement, clock tree synthesis (CTS), routing, timing closure, physical verification, and design optimization across multiple PVT corners while ensuring timing, power, area, and DRC requirements are met.
I completed my M.Tech in Electronics and Communication Engineering from the International Institute of Information Technology Bangalore (IIIT Bangalore). During my master's, I built a strong foundation in VLSI design through academic projects, research, and extensive hands-on experience with industry-standard EDA tools and digital IC design methodologies.
I'm passionate about semiconductor technology and enjoy solving challenging implementation problems that improve chip performance, power efficiency, and design quality. I believe there's always something new to learn in VLSI, and I continuously work on strengthening my understanding of advanced physical design methodologies and the latest semiconductor technologies.
