What is System on Chip (SoC) in VLSI?

A System on Chip (SoC) is a type of integrated circuit (IC) that integrates all the components of a computer or other electronic system into a single chip. In the field of Very Large Scale Integration (VLSI), SoCs are used to design and manufacture complex electronic systems with a high degree of integration and functionality.

SoCs are a key component of modern electronics and are found in a wide range of devices, including smartphones, laptops, tablets, and many other types of electronic devices. They are used to integrate a variety of functions, including processing, memory, communication, and input/output (I/O) onto a single chip, which reduces the size, cost, and power consumption of the system.

In VLSI design, SoCs are typically designed using a combination of hardware and software components, including processors, memory, I/O interfaces, and other peripherals. These components are integrated onto a single chip using a combination of standard cell-based design and custom layout techniques.

By integrating all the components of a system onto a single chip, SoCs can significantly reduce the size of electronic devices.

Low power consumption

SoCs can operate at lower power levels due to their high degree of integration and efficient design.


SoCs can be more cost-effective than traditional ICs due to their high degree of integration and the use of standard cell-based design techniques.

Improved performance

SoCs can offer improved performance due to their efficient design and the use of high-performance components.


SoCs can be customized to meet the specific requirements of different electronic systems, making them highly flexible and adaptable.


SoCs can offer improved reliability due to their high level of integration and the use of advanced testing and validation techniques during the design process.

Integration of advanced features

SoCs can enable the integration of advanced features such as artificial intelligence (AI) and machine learning capabilities, enabling the development of intelligent electronic systems.

Reuse of design elements: SoCs can allow for the reuse of design elements and Intellectual Property (IP) blocks, which can help to reduce design costs and time-to-market.

Design tools and methodologies

Specialized design tools and methodologies have been developed specifically for the design and manufacture of SoCs, which can help to streamline the design process and improve design efficiency.
