摘要： A binning process uses curve fitting to create and assign one or more bins based on testing data of operating voltage versus leakage current for test integrated circuits. Each bin is created by assigning an initial operating voltage to the bin and fitting a curve to the testing data population. An equation is generated describing the fitted curve. Integrated circuits are binned by measuring the leakage current at a selected operating voltage and testing the integrated circuit at one or more operating voltages determined based on the fitted curves. The integrated circuits are assigned a maximum operating voltage that corresponds to the lowest tested operating voltage at which the integrated circuit passes the test.

摘要： A device includes an integrated circuit programmed with an operating surface equation. The operating surface equation may define an operating point as a function of operating voltage, operating frequency, and leakage current. The operating surface equation may be generated by fitting a surface equation to data for operating voltage and operating frequency versus leakage current for a plurality of test integrated circuits. An operating voltage of the integrated circuit at a given operating frequency may be determined by the operating surface equation and a leakage current value fused into the device.

摘要： In an embodiment, the amount of supply voltage guardband to prevent incorrect operation due to aging effects may be modeled using an IC-specific age model generated early in the product life cycle of the IC. For example, high temperature operating life (HTOL) testing may be performed at multiple temperatures and/or voltages to develop the IC-specific age model. The IC-specific age model may be more accurate then the calculations used to develop guardband voltage as discussed previously, which rely on the aging of a single transistor. The IC-specific age model may be used along with monitoring of the aging effects during operation of the IC to predict an amount of increased guardband voltage that is currently desirable to apply to the IC. The predicted amount may vary from about zero when the IC is new to the full amount of guardband voltage when the IC is nearing end of life.
