    摘要: In one embodiment, a test system tests a device under test (DUT). The DUT includes an internal test controller that executes built-in self-test (BIST programs. Built-in self-test programs include array-based automatic built-in self-test programs, discrete and combinational logic built-in self-test programs, and functional architecture verification programs (AVPs). An external manufacturing system test controller manages the internal test controller within the DUT and determines minimum operating voltage levels for a power supply input voltage that supplies the DUT. A logic simulator provides a modeling capability to further enhance the development of minimum voltage power supply input operational values for the DUT.

    摘要: A system and method for determining a guard band for an operating voltage of an integrated circuit device are provided. The system and method provide a mechanism for calculating the guard band based on a comparison of simulated noise obtained from a simulation of the integrated circuit device using a worst case waveform stimuli with simulated or measured power supply noise of a workload/test pattern that may be achieved using testing equipment. A scaling factor for the guard band is determined by comparing results of a simulation of a workload/test pattern with measured results of the workload/test pattern as applied to a hardware implementation of the integrated circuit device. This scaling factor is applied to a difference between the noise generated through simulation of the workload/test pattern and the noise generated through simulation of the worst case current waveform to generate a guard band value.

    摘要: A system and method for generating a worst case current waveform for testing of integrated circuit devices are provided. Architectural analysis of an integrated circuit device is first performed to determine an initial worst case power workload to be applied to the integrated circuit device. Thereafter, the derived worst case power workload is applied to a model and is simulated to generate a worst case current waveform that is input to an electrical model of the integrated circuit device to generate a worst case noise budget value. The worst case noise budget value is then compared to measured noise from application of the worst case power workload to a hardware implemented integrated circuit device. The worst case current waveform may be selected for future testing of integrated circuit devices or modifications to the simulation models may be performed and the process repeated based on the results of the comparison.

    摘要: Systems and methods for positioning thermal sensors within an integrated circuit in a manner that provides useful thermal measurements corresponding to different parts of the integrated circuit. In one embodiment, an integrated circuit includes multiple, duplicate functional blocks. A separate thermal sensor is coupled to each of the duplicate functional blocks, preferably in the same relative location on each of the duplicate functional blocks, and preferably at a hotspot. One embodiment also includes thermal sensors on one or more functional blocks of other types in the integrated circuit. One embodiment includes a thermal sensor positioned at a cool spot, such as at the edge of the integrated circuit chip. Each of the thermal sensors may have ports to enable power and ground connections or data connections between the sensors and external components or devices.
