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. Ehrler
Company: Advanced Micro Devices
Position: Principal Member Technical Staff
Manager Global CAD Infrastructure
Education: BS Computer & Information Science
College of Engineering
The 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.
