Design and Implementation of VLSI Systems Lecture 01 Thuan Nguyen Faculty of Electronics and Telecommunications, University of Science, VNU HCMUS Spring 2011 1 LECTURE 01: THE BIG PICTURE 2 Introduction 1 Overview of VLSI Design Flow 2 Class logistics 3 LECTURE 01: THE BIG PICTURE 3 Introduction 1 Overview of VLSI Design Flow 2 Class logistics 3 INTRODUCTION  A VLSI (Very Large Scale Integration) system integrates millions of “electronic components” in a small area (few mm 2  few cm 2 ).  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? pMOS nMOS 1.Transistors CMOS logic gates + 2. Wires = Circuits design 5 HOW DOES AN IC LOOK LIKE FROM THE INSIDE? transistors wires R. Noyce J. Kilby 6 TECHNOLOGY SCALING Moore’s Law. The number of transistors in an integrated circuit doubles every 2 years. Quad core from Intel: ~600 million transistors in 286 mm 2 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? 7 FEATURE SIZES Human Hair ~75 m 0.18 m 180 nm feature . . ~40,000 (65-nm node) transistors could fit on cross-section [C. Keast] 8 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 BIGGEST SEMICONDUCTOR COMPANIES 10 [...]...LECTURE 01: THE BIG PICTURE 1 Introduction 2 Overview of VLSI Design Flow 3 Class logistics 11 OVERVIEW OF VLSI DESIGN FLOW Video 1  Video 2  12 VLSI DESIGN FLOW 13 BOTTOM-UP (FULL CUSTOM) DESIGN METHOLOGY 14 TOP-DOWN (STANDARD CELL) DESIGN METHOLOGY 15 FROM MASK LAYOUT TO FABRICATED CHIP 16 SIMPLIFIED VLSI DESIGN FLOW 17 SIMPLIFIED VLSI DESIGN FLOW 18 SIMPLIFIED VLSI DESIGN FLOW 19 SIMPLIFIED VLSI. ..
