SANTA CLARA, Calif. — (BUSINESS WIRE) — May 16, 2011 — Extreme DA™, the leader in new-generation timing analysis software, announced it has been issued a patent by the United States Patent and Trademark Office for its method of “Statistical delay and noise calculation considering cell and interconnect variations.” The patent, #7,890,915, covers technology used for improvement of design performance and reduction in power consumption and die-size of digital IC designs produced in nanometer silicon processes. Extreme’s GoldTime software takes full advantage of this technology in its POCV and SSTA analyses to deliver a dramatic breakthrough in calculation speed and accuracy of results.
As IC technologies are scaled to finer feature sizes, it becomes increasingly difficult to control process and environmental variations. The increasing fluctuations in manufacturing processes cause uncertainties in circuit behavior, and significantly impact the circuit performance and product yield. The problem is made worse by the growing sensitivity of current designs to environmental fluctuations, such as variations in temperature and voltage supply.
This new electrical circuit timing method calculates statistical delay, noise and cross-talk with respect to different circuit elements including cells and interconnect wiring, and variations from the silicon process and the operating environment. All the sensitivity computations are based on closed-form equations. As a consequence, Extreme’s new method delivers a dramatic breakthrough in speed and accuracy of analysis for integrated circuits manufactured in the latest nanometer silicon technologies.
"This patent is an innovative new approach to performing delay calculation and signal-integrity analysis taking into account statistical effects," said Mustafa Celik, CEO. "It describes the next-generation capability needed by leading-edge digital designers for complex nanometer designs. Layering statistical analysis on top of traditional timing engines does not have the speed and capacity that is required. We believe the innovations in GoldTime’s POCV and SSTA analysis delivers a breakthrough that eliminates over-design and optimizes IC performance and yield in the most complex designs."
About GoldTime — The New Standard in Sign-off Timing
GoldTime by Extreme DA, is the new-generation timing analysis technology that delivers 5X better speed and capacity. With its new from-the-ground-up architecture, designers can sign-off with certainty and achieve faster timing closure. Whether verifying a current generation design across corners or doing a statistical analysis to optimize the performance, power and yield for 40nm ICs, GoldTime delivers the answers while the competition is still figuring out the results.
