Introduction
What is VLSI chip design?
VLSI chip design is the process of creating integrated circuits (ICs) that contain millions or billions of transistors on a single chip. These chips can perform complex functions such as microprocessors, memory, graphics, communication, etc. VLSI chip design involves various stages such as specification, architecture, logic design, physical design, verification, testing, fabrication, etc.
Why use Cadence and Synopsys CAD tools?
Cadence and Synopsys are two of the most popular and widely used CAD tool vendors in the semiconductor industry. They offer a comprehensive suite of tools that cover all aspects of VLSI chip design from concept to silicon. Some of their flagship products include:
