Introduction to Low Power Design in VLSI M.tech ECE Presentation:

The electronics industry has achieved a consistent growth over two decades mostly to the advances in integration technologies and large-scale systems design – i.e. due to the advent of VLSI. The number of applications based on integrated circuits resulted in high-performance computing, telecommunications, and consumer electronics has been increasing. In this paper we discuss about VLSI, its design styles and its design cycle.

One of the most important characteristics of for today’s services focuses on the higher bandwidth and also high processing power. The other characteristic which is focused more is the personalized services to the user depending on the user requirement which includes the flexibility also the mobility feature.

When we consider VLSI design styles, several design styles can be considered for chip implementation of specified algorithms. Each design style has its own advantages as well as disadvantages and thus an appropriate choice has to be made by designers in order to provide the functionality at low cost. It includes Field Programmable Gate Array an array of logic cells connected via routing channels. These cells include Special I/O cells and logic cells. When we consider that other design style which comes after FPGA is Gate Array, which is capable of processing fast. The implementation includes with the metal mask design and also processing.

The GA chip utilization factor is higher when compared to that of FPGA and in terms of speed also it is higher. One of the most custom design styles is Semi-Custom design style. All the used logic cells are developed and characterized and stored in cell library. When we consider the full custom design, the mask design implemented without the usage of the library.
