VLSI stands for Very Large Scale Integrated circuits that consists of millions of transistors and its main purpose is to reduce the area, improve the speed of the chip, and reduce power losses. In each and every electronic device, Integrated Circuits are used. So, the demand for VLSI engineers is increasing day by day. The VLSI sector is a highly technical field that is completely based on electronics and electrical engineering. One needs to be strong enough in the engineering subjects like circuit analysis ,digital electronics,Verilog etc. Also one must be familiar with the EDA tools that are used in chip design.
