  • Method for adaptively utilizing programmable logic devices
    Patent number: 11385287
    Abstract: Examples described herein provide a method for evaluating a programmable logic device (PLD) for compatibility with user designs. The method includes using a processor-based system: obtaining an indication of one or more failure bits of configuration memory of a programmable logic device (PLD); determining whether each of the one or more failure bits corresponds to a configuration memory bit to be used by a first PLD user design; if any of the one or more failure bits corresponds to a configuration memory bit to be used by the first PLD user design, classifying the PLD as unusable for the first PLD user design; and if none of the one or more failure bits corresponds to a configuration memory bit to be used by the first PLD user design, classifying the PLD as usable for the first PLD user design.

  • Internal voltage level shifting for screening cold or hot temperature defects using room temperature testing
    Patent number: 8030954
    Abstract: Operation of an internal voltage supply level (Vgg) of an IC is characterized over operating temperature or at a selected temperature to determine a temperature-equivalent internal voltage level. The internal voltage supply of the IC is set to the temperature-equivalent level, and the IC is tested at room temperature to screen for low-temperature defects or high-temperature defects.
