Th e cost per f uncti on d ecreases two f old • But... – How can we design a chip with more functions? – Engineering population doesn‘t double every 2 years • So: we need better and efficient design techniques: – Take advantage of abstraction levels 19 Design Abstraction Levels SYSTEM MODULE + GATE CIRCUIT DEVICE G S D n+ n+ 20 Cost per Transistor cost: ¢-per-transistor 1 0.1 Cost of fabrication per transistor (Moore’s Law) 0.01 0.001 0.0001 0.00001 0.000001 0.0000001 1982 1985 1988 1991 1994 1997 2000 2003 2006 2009 2012 21 Some examples (1994) Xip Metal Line Wafer Defects Area Dies/ Yield Die 2 Layers width Cost / cm mm2 wafer cost 386DX 2 0.90 $900 1.0 43 360 71% $4 486 DX2 3 0800.80 $1200 101.0 81 181 54% $12 Power PC 4 0.80 $1700 1.3 121 115 28% $53 601 HP PA 7100 3 0.80 $1300 1.0 196 66 27% $73 DEC Alpha 3 0700.70 $1500 121.2 234 53 19% $149 Super 3 0.70 $1700 1.6 256 48 13% $272 Sparc Pentium 3 0.80 $1500 1.5 296 40 9% $417 22 Design tools • VLSI system design is a complex process which requires automatization of the synthesis cycle. That’s why we need design tools. • There are three families of tools: – Synthesis tools • They allow a physical representation of circuits expressde in HDL (Hardware Definition Languages). – Analysis and Verification • They guarantee the specifications and the correctness of the design – Testing tools • They verify that there have been no errors on the fabrication process. 23 Historical Perspective Ramon Canal CTD – Master CANS CTD – Master CANS 24.
