VLSI, an acronym for Very Large Scale Integration is a technology to place thousands (even more) of electronic components onto a single chip. Currently VLSI architecture is employed everywhere in electronic devices such that TV, computer, laptop and mobile phones.
VLSI design comprises of Front End Design and Back End design. While front end design includes digital design using HDL, design verification through simulation and other verification techniques, the design from gates and design for testability, backend design comprises of CMOS library design and its characterization. It also covers the physical design and fault simulation.
