ProgressMoving very well, making good progressSample design submittedMilestones agreed onFinalize plug-in design for simple delay calculationSelect implementation platformMatch data structure needs between OA and 1481 => no data translation stepsEnhance delay calculation for instance based IR drop/xtalk/parasitic reduction etcAdd power calculation design/implementationAdd functional modeling/implementationSSTA + other OMC/OA WG changes to OMC

RoadmapFinalize plug-in design for simple delay calculation– Tentative milestone completion: Nov-Dec 2006

Select implementation platform– Timing engine to be used in the reference flow and in proof of concept implementation – Tentative milestone completion: Jan-Feb 2006

Match data structure needs between OA and 1481– Develop API and information model definition for timing arcs and nodes data structures to be used by the plug-in in

working with 1481 library– Tentative milestone completion: Apr-May 2007

Statistical Timing Working Group

Request for Technology issued

Si2, on behalf of the Statistical Working Group (SWG) within the Open Modeling Coalition, is seeking proposals for providing extensions to current formats and languages to support statistical timing, as described below: – A Liberty-based static format extension that provides a way to communicate

statistical parameters used to do timing sign-off for designs. Preference will be given to formats compatible with existing Si2 licensed formats.

– A dynamic IEEE1481-based format that provides a way to extend the current timing API to include statistical parameters as part of the requested calculation.

– Any other contributions in the areas of statistical analysis (e.g. characterization, simulation) that apply to the OMC architecture will be entertained.

Biography

Name: Timothy J. EhrlerCompany: Advanced Micro DevicesPosition: Principal Member Technical Staff

Manager Global CAD InfrastructureEducation: BS Computer & Information Science

College of EngineeringThe Ohio State University

Timothy received his BS in Computer and Information Science from The Ohio State University, College of Engineering, joining Industrial Nucleonics as Test Systems Analyst, followed by 14 years with Honeywell Information Systems / Groupe Bull developing and managing their proprietary HDL-based Design Language System for large mainframe computer system design.

Timothy joined VLSI Technology, Inc., in 1993 as a staff software engineer for the development of the integrated ASIC design environment from library view generation to tool development, acquiring 2 patents for IC library timing & analysis. He managed the ASIC tools development group and, after the acquisition by Philips Semiconductors, managed ASIC Technical Programs. He architected the Chip Physical Architecture design area of the Philips SoC Design Environment and led the efforts within Philips in migrating towards OpenAccess based/compliant design environments.

Timothy joined AMD (Advanced Micro Devices) in June 2006 as a Principal Member of the Technical Staff, and is manager of Global CAD Infrastructure. He serves as the AMD representative on the OpenAccess Change Team and the Open Modeling Coalition Technical Steering Group. He also currently chairs the OMC and is a member of the IEEE 1481 standard committee.

~~~~~

Timothy has contributed to the Advanced Library Format (ALF), now IEEE 1603, and led the migration effort within VLSI/Philips from a proprietary environment to ALF. He led efforts toward adoption of OLA libraries and EDA tools within Philips as a member of the Open Library Architecture (OLA) / IEEE-1481v2 working group.

Timothy participates in the OpenAccess Coalition as a Change Team member, was a member of the Golden Gate working group, chaired the Timing Working Group, and developed the source-core timing constraints now undergoing beta-test. He also served as chairman of the Open Modeling Coalition and is now AMD’s representative & Technical Steering Group member, chaired its Joint Data Model Working Group to define/develop an OpenAccess plug-in for OMC library architecture access, and is a member of the related IEEE 1481 standards group for version 2 balloting in 2006.
