L ECTURE 01: THE BIG PICTURE

L ECTURE 01: THE BIG PICTURE

 A VLSI (Very Large Scale Integration) system integrates millions

of “electronic components” in a small area (few mm2  few

cm2)

 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

WHAT ARE VLSI SYSTEMS COMPOSED OF?

HOW DOES AN IC LOOK LIKE FROM THE INSIDE?

transistors wires

TECHNOLOGY SCALING

Moore’s Law The number of transistors in an integrated

circuit doubles every 2 years

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!
