  • Patent number: 8863058
    Abstract: A method for timing optimization of an integrated circuit design using a timing optimization system comprising loading an original delay value and an original gate configuration net-list for an original gate from a results database. A near optimum gate configuration is identified using near optimum gate configuration information stored in a delay characterization database for the original gate. A near optimum delay value and a near optimum gate configuration net-list of a near optimum gate configuration are loaded. A timing optimized gate configuration is provided from running an incremental static timing analysis of the near optimum gate configuration.

  • Publication number: 20140298281
    Abstract: System-on-chip (SoC) designs include large amounts of interconnected intellectual property blocks and standard-cell logic using complex bus fabrics. Today SoC design-closure that validates design targets of area, timing, congestion and power constraints is accomplished post routing as over 80% of validation problems are due to global-interconnect. A method is disclosed that allows the designers to achieve global design-closure and physical topology constraints, early in the design cycle, at much higher levels of abstraction. In particular, logic hierarchy of the design is converted into a physical hierarchy of functional-related clusters of locally-connected logic. The clusters and inter-cluster global connections can be refined to meet design constraints in order to generate a top-level floor-plan in the form of library and constraint files.
