The Open Modeling Coalition (OMC) is made up of three levels. At the top is the OMC itself. Reporting to the OMC is an elected Technical Steering Group. Reporting to the TSG are domain specific Working Groups. The current active working groups are: ECSM-CMG, Statistical, JDM, and Characterization. The OMC architecture is available on the Si2 website and is well worth perusing. (Also see diagram below)

The OMC is making good progress. The Statistical Static Timing model: Statistical ECSM was approved by the OMC TSG and has now exited the 60 day exclusion period. Si2 is recommending approval of the S-ECSM specification as an Si2 standard by the OMC. A two-week window set for e-vote by OMC members started on 09/12.

The OMC has a defined architecture (see diagram below). A partial reference flow 1.0 of this architecture was demonstrated at DAC 2007. Attendees were excited with the demonstration and interested in the future of the project. The Joint Data Modeling working group took the feedback from the demonstration and has turned the proof-of-concept into a formal OpenAccess extension prototype, which will be demonstrated at the OpenAccess Conference in November.

There has long been an open question about ECSM and CCS non-convergence. Is it a real issue or hype? To that end, Si2 has sent out a survey to over 2,000 recipients to understand the costs of non-convergence. These results will be used to drive the next steps on this issue.
