ITRS Design ITWG 2008 1
Design and System Drivers
Worldwide Design ITWG
Key messages:1.- Software is now part of semiconductor technology roadmap 2.- Design technology has become key to technology control 3.- Design pacing unabated despite manufacturing slowdown4.- MtM will bring a new set of Design requirements/solutions (09)
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)
(alternative Scenario)

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

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)
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
Trend: Memory Static Power Trend: Logic Static Power
Trend: Memory Dynamic Power Trend: Logic Dynamic Power
Requirement: Dynamic plus Static Power

Design Pacing Unabated Despite Manufacturing Slowdown Impact of 3-year shift on System Drivers
– 2008: MPU frequency model intact– 2008: Consumer driver model power updates to reflect 3-year GL shift– 2009: Incorporate impact of FINAL parameters from 3-year shift
Updated Consumer portable (power)
Updated MPU model (power)
PIDS / FEP / Litho 3-year shift

More Than Moore Brings Alternative Set of Parameters (2009-10) Will create additional inventory of parameters
New System Drivers? Not So Fast…• New FPGA driver suspended (until resource identified)• Others (defense) eliminated to synchronize with latest iNEMI• Others might be assessed in 2009 (medical, automotive)

Design & Key ITRS Cross-TWG Initiatives
With Interconnect (A&P): 3D / TSV roadmapping survey
With PIDS, FEP, IRC: Modeling and requirements support for CV/I RO-based transistor metric
With CSTNSG: Updated frequency, SRAM area, active area (yield) projects
With More Than Moore Study Group: Definition of SIP-scenario System Driver roadmaps to complement existing SOC-scenario Driver roadmaps
