  • Patent number: 8843874
    Abstract: A method of optimizing power and timing for an integrated circuit (IC) chip, which uses an IC technology that exhibits temperature inversion, by modifying a voltage supplied to the IC chip, while meeting power consumption and timing delay performances across lower and higher temperature ranges. A high voltage is selected that meets a closed timing analysis across a full temperature range to meet a timing performance and a low voltage is selected to meet the timing performance and the power performance across a lower temperature range to a temperature cut point in the higher temperature range. The IC chip is turned on at the high voltage and the high voltage is lowered to the low voltage when the temperature cut point is exceeded to meet the power performance while maintaining the timing performance.

  • Patent number: 8839177
    Abstract: Disclosed are integrated circuit design systems and methods, wherein selected functional library elements are placed in a layout to meet product specifications and selected hybrid fill-placeable library elements are placed in that same layout to meet at least one feature density rule. Each hybrid fill-placeable library element comprises fill shapes corresponding to specific features subject to a density rule and a marker shape that provides an instruction to ignore any density rule violations within that element for purposes of design rule checking. Placement of the hybrid fill-placeable library elements is performed to balance out density rule violations in functional library elements elsewhere in the layout, thereby avoiding the need for post-processing of the completed IC design to add fill shapes.

  • Patent number: 8839170
    Abstract: A method of optimizing power and timing for an integrated circuit (IC) chip, identifies a plurality of valid temperature and voltage combinations that allow integrated circuit chips produced according to the integrated circuit chip design to operate within average power consumption goals and timing delay goals. Such a method selects temperature cut points from the valid temperature and voltage combinations for each of the integrated circuit chips, calculates a power consumption amount of each of the temperature cut points, and adjusts the temperature cut points based on the power consumption amount until the temperature cut points achieve the average power consumption goals. Next, this method tests each of the integrated circuit chips, and records the temperature cut points in the memory of the integrated circuit chips.

  • Publication number: 20140074422
    Abstract: A plurality of digital circuits are manufactured from an identical circuit design. A power controller is operatively connected to the digital circuits, and a non-transitory storage medium is operatively connected to the power controller. The digital circuits are classified into different voltage bins, and each of the voltage bins has a current leakage limit. Each of the digital circuits has been previously tested to operate within a corresponding current leakage limit of a corresponding voltage bin into which each of the digital circuits has been classified. The non-transitory storage medium stores boundaries of the voltage bins as speed-binning test data. The power controller controls power-supply signals applied differently for each of the digital circuits based on which bin each of the digital circuit has been classified and the speed-binning test data.

  • Publication number: 20140046466
    Abstract: Disclosed are embodiments of a method, system and computer program product for optimizing integrated circuit product yield by re-centering the manufacturing line and, optionally, adjusting wafer-level chip dispositioning rules based on the results of post-manufacture (e.g., wafer-level or module-level) performance path testing. In the embodiments, a correlation is made between in-line parameter measurements and performance measurements acquired during the post-manufacture performance path testing. Then, based on this correlation, the manufacturing line can be re-centered. Optionally, an additional correlation is made between performance measurements acquired during wafer-level performance testing and performance measurements acquired particularly during module-level performance path testing and, based on this additional correlation, adjustments can be made to the wafer-level chip dispositioning rules to further minimize yield loss.

  • Publication number: 20140039664
    Abstract: Methods and systems optimize power usage in an integrated circuit design by sorting the integrated circuit devices after manufacture into relatively slow integrated circuit devices and relatively fast integrated circuit devices to classify the integrated circuit devices into different voltage bins. The methods and systems establish a bin-specific reliability testing processes for each of the voltage bins and test the integrated circuit devices using a tester. This allows the methods and systems to identify as defective ones of the integrated circuit devices that fail the bin-specific integrated circuit reliability testing processes of a corresponding voltage bin. The methods and systems remove the defective ones of the integrated circuit devices to allow only non-defective integrated circuit devices to remain and supply the non-defective integrated circuit devices to a customer.
