  • Method and apparatus for performing incremental delay annotation
    Patent number: 8286109
    Abstract: A method for designing a system on a target device includes identifying components and routing connections impacted by incremental design changes made to a system design. New information is computed to annotate delays for the components and routing connections identified. Delays previously computed for components and routing connections are utilized to annotate delays for components and routing connections that have not been impacted by the changes made to the system design.
