Open Modeling Coalition Approves Statistical Extensions in Si2's ECSM Standard

AUSTIN, Texas—(BUSINESS WIRE)—November 5, 2007— The Silicon Integration Initiative's Open Modeling Coalition has voted to approve the Effective Current Source Modeling (ECSM) Statistical Extensions as an Si2 standard. The statistical version of ECSM is available to the broad electronics industry, both users and EDA vendors alike, regardless of Si2 membership.

The ECSM statistical extensions accurately and efficiently model the impact of process and environmental variation - a potentially performance depriving problem - which can negate many of the advantages of moving to process nodes at or below 65nm. Using a statistical approach to timing analysis allows designers to unlock the true potential of smaller process technologies by reducing the pessimism that can rob chip performance in traditional design methodologies. The key to this new statistical standard is that it uses sensitivities to process and environmental device parameters to holistically model variations around nominal operating points. The statistical format accurately accounts for global, within-the-die, and random variations. The net result - fewer analysis corners, increased chip performance, and better silicon.

"Statistical analysis allows designers to understand how variation impacts their timing performance, removing the need to use overly pessimistic guard bands," said Jim McCanny, CEO of Altos Design Automation, Inc. "Using an industry standard statistical library format will enable all the key components of the design flow to adopt and benefit from statistical analysis. Indeed, Altos already supports Si2's S-ECSM format with its latest Variety 1.4 product release."

"Open standards provide an equal opportunity for EDA vendors, IDMs, fabless IC companies, and foundries to integrate into mainstream design flows and deliver innovative technology directly to end-markets," says Sumit DasGupta, sr. vice president of Si2. "We applaud the OMC for approving this important new standard for the benefit of the entire industry"
