EDA Standards Roadmap: Si2 View

• Sets direction for all of industry

– Identifies what is needed and when

– Defines stakeholders/adopters

– Adoption choices

• Identifies potentially disruptive (or radically new)

technologies

– Analyzes impact to standards

– Recommends course of action

• Provides sufficient detail on requirements

– Not too high, not too low

ABK’s Preparatory Questions

• Does Si2 read / pay attention to any of the (ITRS, CATRENE, STRJ) ) roadmaps –

why or why not

– Yes, ITRS regularly

– 1996 EDA Standards Roadmap & 2002 Si2-Dataquest COO Study

• What would make an EDA roadmap more useful to Si2 (R&D, product marketing,

…)

(what would the ‘ideal’ look like)

– Prioritized grouping of requirements

– Key drivers/stakeholders by group willing to lead/adopt

• What are EDA technology areas where the existing road-mapping efforts are most

insufficient or incorrect (multi-core EDA algorithms, ESW verification, analog

test, …)

– Overarching need: Parallel programming paradigm

– ESL: Make it real

– Verification: Still too dependent on CPU cycles

– Analog synthesis / DFT / TPG / test,…

• What are areas where the EDA industry has fallen behind the curve e (and,

roadmap goals need to be instituted or revised)

– Ask the users

Drivers for Current Si2 Projects

• 1996 EDA Standards Roadmap: Top-5

recommendations:

– Chip data representation (CHDStd(

CHDStd)

– Synthesizable subsets

– Delay project (DCS/DCL)

– Software licensing policy

– Open modeling forum (OMF)

• 2002 Si2-Dataquest COO Study:

– Interoperability,…

• ITRS (multiple versions):

– Modeling interface

– Low power

– DFM,…

Silicon Integration Initiative

Example Si2 Project: OpenAccess

• Charter:


Develop open, industry standard API and reference

implementation for EDA tool interoperability

– Currently in use by all 4 major vendors and many small vendors

– Adopted by IDM’s and end-user companies

• Original Driver:


1996 EDA Standards Roadmap

• Current Drivers – User Requirements:



Semiconductor technology requirements

User-driven chip design challenges – TTM, performance,

design closure, interoperable design flows…

Silicon Integration Initiative

Example Si2 Project: Low Power

• Charter:



Define/enhance standard format (CPF) for low power design

constraints ( focus on syntax & semantics)

Develop flows and enablers to enable ESL2GDS chip design

• Original Driver:



User/member request

2005 ITRS

• Current Drivers – User Requirements:




Continue CPF enhancements to address industry needs

– Address interoperability with 1801-2009

Define modeling requirements for ESL2GDS flows

Define OpenPower API standard and OA extensions to serve

as agnostic container for power constraints

Silicon Integration Initiative

3D Design

• Charter:



New project - hot off the presses!

Develop standards to support 3D chip design

• Original Driver:



User/member request

2007 ITRS

• Next Steps:




Sponsor workshop to scope out problem / requirements

Recruit potential stakeholders / adopters

Form TAB to define / implement goals and objectives

– Near term:

4 – 6 months

– Longer term: 12 – 24 months
