 Something in the following paper had me thinking Ignite/Inflame. Comments welcome.  Could Toshiba be Partnering with PTSC in the future?

Couldn't sleep so I thought I'd hang out here.  lol

NEW TECHNICAL PAPER FROM TOSHIBA ADDRESSES POWER-SAVING CLOCK-GATED DESIGN FOR HIGHER PERFORMING CUSTOM SOCS


SAN JOSE , Calif., July 23, 2007Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the publication of a new Pointers & Pitfalls technical paper entitled “Power-Saving Clock-Gating Technique is an Inseparable Part of SoC Design.” The new technical paper explains that strict chip power requirements have led to clock gating increasingly becoming an inseparable part of custom system-on-chip (SoC) design. Compared to similar non-clock-gated designs, clock-gated designs theoretically can achieve both lower power consumption and improved timing performance. The biggest power-savings of clock-gating are manifest in dataflow-intensive designs. In portable electronics systems, the system-level benefits of clock gating can include longer battery life, improved reliability and less costs associated with heat reduction.

The document shows a general implementation flow for clock-gated designs and culminates with a comprehensive list of pointers and pitfalls. For example, at the RTL phase, it is important to perform power simulation to confirm the power savings before incorporating clock gating into the design. Also, designers should remember to provide extra timing margins for the clock signals to the clock gates. The paper cautions that soft clock gates should be avoided as they require specialized layout work; instead, integrated clock-gate cells from the ASIC library should be used. Toshiba offers a suite of design tools and methodologies to support the entire process of clock gating, including static timing analysis, clock tree synthesis, design-for-testability and dynamic power analysis.

The Pointers & Pitfalls series of technical papers provide engineering and design insights to help engineers understand evolving custom SoC design issues and support their product planning decisions. The company invites designers to tap into this deep system-level expertise to enable higher productivity and greater success.
