Very Large Scale Integration Design and Its Applications

Very Large Scale Integration Design and Its Applications: The concept of Very-large-scale integration (VLSI) is the part of semiconductor and communication technologies. It is integrated circuits on a single chip. It is the first semiconductor chips that held one transistor. The microprocessor is a VLSI device. It involves implementation and designing of circuits. It provides computational speed with minimum power dissipation and circuit board area. This paper covered the evolution of VLSI design concepts and methodologies used such as future challenges, fabrication process, limitations, and some applications.

Very Large Scale Integration (VLSI) describes about semiconductor integrated circuits which composed of hundreds of thousands of memory cells logic elements. It is the technique of implementation circuit designing that provides computational speed.

Therefore, this technique provides less area/volume. Hence compactness, less testing requirements, less power consumption, higher reliability due to improved on-chip interconnects, higher speed, due to significantly reduced interconnection length, and significant cost savings.

The design flow begins from the algorithm. This algorithm describes the behavior of the target chip. By floor planning, it is placed onto the chip surface. The design evolution defines Finite State Machines (FSMs) that are implemented with functional modules.

Using CAD tools, these modules are mapped onto the chip surface for automatic module with a goal of minimized interconnects area and signal delays. At the third stage, the chip is mentioned in terms of logic gates by using routing program and a cell placement.

VLSI Design Styles are in the following ways, which are Field Programmable Gate Array (FPGA), Gate Array Design, Standard-Cells Based Design, and Full Custom Design. Applications of this design are Multimedia and VLSI in Communication.


VLSI gives circuit designs with high computational speed and less power dissipation and less circuit board area, with higher speeds and higher reliability at lower costs. VLSI has revolutionized and has a wide range of applications in the electronic industry.
