VLSI Design

VLSI (Very Large Scale Integration) Design is a cornerstone of computer engineering that involves the process of creating integrated circuits (ICs), or microchips, by combining millions to billions of transistors onto a single silicon chip. This highly complex engineering discipline encompasses the entire workflow from system-level specification and logic design to the physical layout, verification, and testing of the final hardware. Utilizing sophisticated computer-aided design (CAD) tools, VLSI designers create the foundational components of all modern electronics, including microprocessors, memory chips, and application-specific integrated circuits (ASICs) that power everything from smartphones to supercomputers.
