System Level Design & SOFTWARE Hardware design productivity is growing appropriately
– Requirements correspond roughly with solutions– Innovations pacing properly (transistors / designer / year)
Large gap in software productivity possibly opening up– If hardware accelerators are heavily leveraged, problem mitigated– Otherwise, possibly 100X gap can affect memory size, other
Adding new parameters to requirements/solutions tables– Hardware design productivity - requirement– Software design productivity - requirement– Software design productivity (assuming only software implementation)– System design productivity innovations – solutions (Fig. 1 in chapter)

Impact of Design on “Sigma” (Variability)
Manufacturing
Device
Circuit
Logic / function
System / SW
Use variability model
Goal Quantify “how many sigmas” can design “reduce”
Approach Inventory of design techniques / toolsMatch inventory to parameters or correlations in modelUse variability model to capture “delta” in sigmas
Inputs (manufacturing)
Check overall variation
ITRS Design ITWG 2008 5
Technology Pacing (Design) Impact of 3 year shift on Design
– Largely insignificant – number of functions basically unchanged
– Possible impact on selected requirements (e.g., DFM)
Updated Design requirements (DFM)(% variability model, etc.)
PIDS / FEP / Litho 3-year shift
ITRS Design ITWG 2008 6
More Than Moore (Design) More than Moore brings new set of requirements/solutions
– Will create additional inventory of parameters
Existing requirements Existing solutions
Additional requirements Additional solutions
E.g.– System-level (packaging) – Circuit (inter-chip parasitics modeling/simulation)– Layout (SiP global layout)– DFM (package-chip, SiP DFM)

Design and System Drivers
Worldwide Design ITWG
Key messages:1.- Key system drivers constantly updated (2008, 2009,…)2.- Design pacing unabated despite manufacturing slowdown3.- MtM will bring a new set of System Drivers’ parameters (09)4.- Will continue to broaden System Drivers based on markets 5.- Frequency-power trade-off will continue its adjustment 6.- Design/SD ITWG deeply engaged in cross-TWG initiatives

Key System Drivers Constantly Updated Consumer Driver Model 2008: Updated power model with realistic dynamic power
– Memory dynamic power 10X less than modeled previously
Will identify key driver requirements, explore coloring– E.g., excessive power beyond portable limit (1 W)
Will explore RF/A/MS for future portable consumer drivers– Extends existing driver (or, future “wireless” driver is possible)
Also ongoing: additional parameters per Test requests– Upon provision of rationale/definition: Clocks, I/Os, currents, etc.
