What is VLSI?

What is VLSI?

Part 1 – VLSI Basics VLSI – Digital System Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device.

What are the current trends in VLSI?

The current cutting-edge technologies such as high resolution and low bit-rate video and cellular communications provide the end-users a marvelous amount of applications, processing power and portability. This trend is expected to grow rapidly, with very important implications on VLSI design and systems design.

How many transistors does a VLSI designer design per day?

Practically, the designer does the full custom layout, i. e. the geometry, orientation, and placement of every transistor. The design productivity is usually very low; typically a few tens of transistors per day, per designer. In digital CMOS VLSI, full-custom design is hardly used due to the high labor cost.

Why silicon CMOS for VLSI?

Over the past several years, Silicon CMOS technology has become the dominant fabrication process for relatively high performance and cost effective VLSI circuits. The revolutionary nature of these developments is understood by the rapid growth in which the number of transistors integrated on circuit on single chip.
