  • Statistical on-chip variation timing analysis
    Patent number: 8307317
    Abstract: A statistical on-chip variation approach to timing analysis permits the automated or semi-automated selection of design-specific margins without requiring complex statistical libraries. By separately addressing the impact of random and systematic variations on timing, a design-specific margin can be obtained and used in downstream OCV analysis. In addition, where statistical libraries are available for some portions of a design, these can be incrementally included in the timing analysis to obtain more accurate results.
    Type: Grant
    Filed: August 1, 2011
    Date of Patent: November 6, 2012
    Assignee: Synopsys, Inc.
