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.
