With technology and business in a state of flux, speed of thought and competitiveness are the criteria, which separates the best from the rest. In order to equip our students with the most current in this ephemeral technological field we have set up a state-of-the-art laboratory, which is upgraded periodically. We have also added latest topics like VLSI design and Embedded Technology to keep students aware of the recent changes. Students are offered VLSI design as an elective in the sixth semester. This helps them a lot when they attend their placement interviews.
