VLSI Layout: Concept to Realization

Very large-scale integration, commonly referred to as VLSI, means a process in which an integrated chip is made by merging myriads of Metal Oxide Semiconductor transistors. An example of VLSI device is a microprocessor. In India, VLSI and EDA occupy the largest segment of the Indian semiconductor design industry. While VLSI industry is large in Bangalore, Noida is in charge of the largest EDA operations in India. There are various devices and memories which are used to control a system. For example: Random Access Memory, Central Processing Unit, and, Read Only Memory and various other devices. What VLSI does is that it allows us to integrate all these different parts in just one single chip. This paper presents the development of VLSI, its applications, implementation and recent developments in the technology of Very Large-Scale Integration abbreviated as VLSI. The paper is divided into further sections as Introduction of VLSI, History and development of VLSI, VLSI Design/Layout flow, VLSI Layout styles, Current research to make VLSI more effective, Advantages and Disadvantages of VLSI, Uses of VLSI etc.
