SIA technology roadmap prediction of Gordon Moore: chip compute power *2 per 1,5 year Final presentation ESA-ESTEC 7/3/2001 Georges Gielen 8
! reduction of cost : What is driving integration? " technology used " number of components and passives! higher performance, lower power B De Muer ~ cm 2 ~ mm 2 Final presentation ESA-ESTEC 7/3/2001 Georges Gielen 9
What about space?! integration reduces 3-D volume, weight! increased performance and lower power consumption! cheaper standard technologies Final presentation ESA-ESTEC 7/3/2001 Georges Gielen 10
Need for analog CAD tools! analog is typically small fraction of chip area! but requires disproportionally large part of design effort and is often responsible for design errors! # analog is big problem for mixed-signal systems! # need analog CAD tools to solve this problem!
