10/5/2009 1 Overview of Design Methodologies Lecture 1 ECE 156A 1 My engineering triangle Implementation skills (programming) Self- drive Theoretical sense Application domain knowledge A feel of the market Knowing the limits ECE 156A 2 • A good CE (ECE) engineer should have these three aspects of knowledge and skills – Don’t have implementation skills -> marketing – Don’t have domain knowledge -> solving a wrong problem – Don’t have theoretical sense -> cannot be a true R&D

10/5/2009 2 Lectures • Concern “application domain knowledge” • Less on implementation skills or building a strong theoretical sense • I am more interested in teaching things that are difficult to learn by self-study – Market trends –E x p e r i e n c e – Vision and philosophy – Complex algorithms • And I assume you will study those that can be ECE 156A 3 And I assume you will study those that can be learned by self-study – Use the Internet – Practice your Verilog skills – Read papers and other books Design • Chip design is a very complex process • You need to worry about two main things – Functionality – Properties or characteristics – How to ensure those before making the chips? • To start, you need some sort of “formal model”

10/5/2009 3 How Complex? • Over the years, the design industry follows this so-called “Moore’s Law” • By advancing the technologies so fast, we are making chips today that are so complex • The complexity of making chips is so high today that it can go beyond control very soon if we don’t do something about it ECE 156A 5 Moore’s law? • Gordon Moore , Intel co-founder (1968) – Visit http://www.pbs.org/transistor/album1/moore/index.html • Moore’s Law – rule of thumb in semiconductor industry (a reference for competition) – He said that the number of “components” on a single silicon chip would double every 1.X year – Somebody says double every 1 year – Somebody says double every 1.5 years – Most recently, we say “double every 2 years • Some people also say the “ performance double every 1.x year • In short, “industry should move fast!”

10/5/2009 4 Power Wall Power Wal Power Wall Need to turn! • While manufacturing guys are busy improving their process, ECE people are developing new designs and design methods In Summary • In the past 20 years, manufacturing technology improved so fast – That we were busy building more and more complex designs • We didn’t actually have time to really think hard to optimize our design to better utilize the resource such as Power • In the next few years, we will be working on optimizing our designs – Continue to push for better performance – But not utilizing more power
