Quick Answer

What is VLSI?

VLSI (Very Large Scale Integration) is the design of integrated circuits that combine millions of transistors on a single chip.

Definition

VLSI stands for Very Large Scale Integration — the design and fabrication of integrated circuits containing millions to billions of transistors. It underpins modern processors, memory, mobile chipsets and specialised hardware.

In technical terms

VLSI design covers RTL design, functional verification, synthesis, placement, routing, timing closure and physical verification (DRC/LVS).

Real-world examples

The CPU in a laptop.
Mobile SoCs like Apple's A-series and Qualcomm Snapdragon.
GPUs used to train AI models.
