INTRODUCTION
 A VLSI (Very Large Scale Integration) system integrates millions
of “electronic components” in a small area (few mm
2
 few
cm

).
 Class objective: Learn how to design “efficient” VLSI systems
that implement required functionalities.
 What are the design metrics?
• Circuit Speed / Performance
• Power consumption
• Design Area
• Yield

If a pond lily doubles everyday and it takes 30 days to completely
cover a pond, on what day will the pond be 1/2 covered?

WHY SHOULD YOU LEARN ABOUT VLSI
SYSTEMS?
 They are ubiquitous in our daily lives
(computers/iPods/TVs/Cars/…/etc).
 This course can help you understand the devices you use.
• The market for VLSI systems (and semiconductors) is
worth $350 billion dollars.
 This course can help you get a decent job after graduation (or
you can even start your own company).
• VLSI design and analysis is fun!
