VLSI design introduces students to fabrication and layout techniques necessary to design large scale systems. Specific topics include: CMOS logic, MOSFET theory, layout design rules including all the factors required for an effective circuit design. VLSI means "enormous scope combination" which decides incorporation levels. Device of semiconductor was the driving element of development in the VLSI Technology. VLSI is a Technology by which 10000-1 Million Transistors can be amassed on a solitary chip. VLSI means "extremely huge scope coordination" which decides mix levels.
