Frequent Statements About the Slowing of Technology Adoption “The problem is that Moore's Law has collapsed," he says. Coburn asserts that there has been a slowdown in the previously steady move to smaller geometries and larger wafer sizes. Pip Coburn, Coburn Ventures December 15th, 2008 Source: Barron’s “Why it’s going to get a lot worse,” Eric J. Savitz. Dec. 15, 2008 http://online.barrons.com/article/SB122912495865802961.html?mod=gartner “The slowdown in process technology transitions will mean that the semiconductor industry will be driven more by economics than technology …” “You are not seeing these geometries rise and fall off the way they did before. Rather, they are living on.” Len Jelinek, Director and chief analyst, Semiconductor Manufacturing, for iSuppli Source: EE Times,“ISuppli: Gear costs to derail Moore's Law in 2014," Dylan McGrath, June 16, 2009 http://www.eetimes.com/news/latest/showArticle.jhtml?articleID=217900102 “And, the customers have slowed down or delayed their technology transitions either by leveraging their existing installed base or just by delaying their new product introduction for later.” Eric Meurice, Chairman, President and CEO ASML Holding N.V.

Myth vs. Reality?Verification Is Keeping Up With Moore’s Law
Size (# transistors) Time (years) An Optimistic View of the Productivity Gap • Let’s assume… • Number of transistor doubles every 18 months (58% / yr) • Amount of logic we can design doubles every 2 years (41% / yr) • Amount of logic we can verify doubles every 2.5 years (25% per year)
DesignGap VerificationGap Ability to Fabricate Ability to Design Design Size in Millions of Gates Ability to Verify Productivity Gap • The Verification Gap • Many companies still using 1990’s verification technologies • Traditional verification techniques can’t keep up * Based on data from the 2003 ITRS, Collett International 2004 FV Survey, and customer surveys 27
The Verification GapDirected TestState-of-the-Art Verification Circa 1990 • Imagine verifying a car using a directed-test approach • Requirement: Fuse will not blow under any normal operation • Scenario 1: accelerate to 37 mph, pop in the new Lady GaGa CD, and turn on the windshield wipers
A Few Weeks Later. . . . . The Verification GapDirected TestState-of-the-Art Verification Circa 1990 • Imagine verifying a car using a directed-test approach • Requirement: Fuse will not blow under any normal operation • Scenario 1: accelerate to 37 mph, pop in the new John Mayer CD, and turn on the windshield wipers
The Verification GapDirected TestState-of-the-Art Verification Circa 1990 • Imagine verifying a car using a directed-test approach • Requirement: Fuse will not blow under any normal operation • Scenario 714: accelerate to 48 mph, roll down the window, and turn on the left-turn signal
Concurrency Challenge • A purely directed-test methodology does not scale • Imagine writing a directed test for this scenario! • Truly heroic effort—but not practical
