INTRODUCTION 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 4
WHAT ARE VLSI SYSTEMS COMPOSED OF? 1.Transistors 2. Wires nMOS + = design pMOS Circuits 5 CMOS logic gates
HOW DOES AN IC LOOK LIKE FROM THE INSIDE? wires transistors 6 J. Kilby R. Noyce
TECHNOLOGY SCALING 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? Moore’s Law. The number of transistors in an integrated circuit doubles every 2 years. Quad core from Intel: ~600 million transistors in 7 286 mm2
FEATURE SIZES Human Hair ~75 m . 0.18 m 180 nm feature . ~40,000 (65-nm node) transistors could fit on cross-section 8 [C. Keast]
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! 9
