IEEE DASC Co-Sponsorshipof UPF Working Group

Proposal prepared by:Stephen Bailey

Chair, Accellera UPF Technical Subcommittee

Agenda

• Request for DASC co-sponsorship of WG

• Background of UPF-TSC

• UPF from start to finish

• IEEE and Accellera relationship

• Working group

• IEEE Timeline

Background for UPF-TSC

4

Industry Need

• Power has become the dominate factor in the design of today’s electronic systems– Explosion in battery operated systems– Many (most) non-portable designs are also constrained by

power consumption requirements• Heat generation and dissipation• Practical power supply & management

• Current state is a hodge-podge of commercial and ad hoc solutions– SAIF, GAF, etc.– Specification of power aware design characteristics

• Often done late at gate-level and ad hoc

– Need to verify correctness of power-aware functionality– Done sooner and with higher correlation to design intent

5

Demonstrated Need• DAC 2006:

– TI and Nokia organized a meeting on the topic of an open standard for low power design flows

– The 4 top EDA vendors attended• Plus Atrenta

– Broad, significant user representation including• TI• Nokia• ARM• ST• Philips• Sun

– Shrenik Mehta represented Accellera• Demand for Open, Fast, Inclusive standard

6

Mission of Accellera Low Power Flow TSC• The accelerated development of an open,

comprehensive standard for the specification of power-aware requirements, design intent and implementation, verification and analysis across all design abstraction levels.

Highlights

• Openness demonstrated throughout– Everyone invited and allowed to participate in TSC

• Accellera membership not required to join

– Documents available to all TSC members

• Fast – Merely 5 months from start to finish

• Inclusive– Unprecedented donations from 8 companies– EDA suppliers and users donated– Members and non-members of Accellera

IEEE and Accellera Relationship

13

Accellera and IEEE

• Accellera has long-standing relationship with IEEE• Accellera Technical Committee Policies, Procedures, &

Guidelines:– All established Accellera standards are eventually planned for

IEEE standardization to speed worldwide acceptance of such standards.

– Specification format, strawman donation and any other ownership documents follow or exceed IEEE rules and guidelines.

• Plan of record is to transfer UPF to IEEE when complete• Since inception of IEEE Corporate Standards Program,

Accellera Board recommends all standards be entity-based– SystemVerilog, PSL, OCI, UPF

CAG/DASC UPF Working Group

15

UPF Working Group

– Submit draft PAR to DASC Chair for SC review and comment NLT 31 Jan 07

– Sponsor PAR jointly with CAG• Draft PAR presented to CAG ~6 Feb 07

– Entity-based– Open to everyone– Initial WG chair: Stephen Bailey

• Conduct elections within DASC required 6 month period for all WG officers

– Follow prior precedent of operating procedures for jointly sponsored WGs

On Convergence

• The UPF WG is willing:– To accept more than one technology donation– Provide the forum for converging multiple

industry formats into a single standard– Change the name of the resulting standard

• Conditions:– Only one: All donations for consideration

must be submitted quickly
