The idea behind VDAT or the VLSI Design And Test Symposium is to promote Research and Development on all aspects of VLSI in India. VDAT began in 1998 as a workshop with about 30 participants at Chennai. With the participation growing steadily each year, from the year 2005, VDAT has acquired the status of a Symposium. The aim of this symposium is to bring academics, researchers, startups, and industrial practitioners together to exchange their ideas in the area of VLSI design, test, and system design. The VLSI Industry in India and academic community working in the area of VLSI have provided immense support to the symposium. The symposium is conducted during July each year, with participation from across the world. VDAT is supported by the VLSI Society of India, with support and sponsorship from leading institutes and the industry.
