Intrinsity deploys Altos’ Liberate to create libraries for signal integrity analysis


Liberate used to characterize 65nm libraries for use at 3Ghz and beyond


San Diego, California --  May 7, 2007 - Altos Design Automation Inc. today announced that Intrinsity Inc.,  an Austin based design technology company, has adopted its library characterization product Liberatetm.


Intrinsity, which provides tools, technologies, and expertise that enable customers to produce high performance, low-power and cost-effective products, is using Liberate to characterize a 65nm standard cell library that includes CCS (Compact Current Source) noise models.


Michael Becker, VP of Engineering said, "Our focus is on designing at and beyond 3 Ghz. At these high frequencies signal integrity (SI) is a major concern. Consequently our libraries need to support the latest current based noise models to ensure accurate SI sign-off analysis and repair."  


Becker continued, "We selected Altos Liberate for library characterization because of its accuracy, ease of use and impressive performance. We also obtained excellent path correlation from static timing analysis when comparing Liberate’s results to using our existing library.”

"Current based noise models are much better than the previous generation of signal integrity models because they enable more accurate modeling of noise rejection, glitch propagation and driver weakening" said Jim McCanny, Altos CEO, "Intrinsity was able to leverage Liberate’s inside view technology that automatically determines the first and last logic stages for each cell along with the appropriate internal probe points required to accurately model noise immunity”.
