    Abstract: The present invention relates to an Operational Life Test (OLT) or "burn-in" technique for testing microprocessors. In accordance with the present invention, an OLT chamber is provided wherein many Evaluation Boards are mounted within racks in a frame in the chamber, each Board being designed for separately exercising its associated microprocessor integrated circuit (IC). During the OLT or burn-in procedure, each Evaluation Boards runs its own internally stored diagnostics, simultaneously with other Boards, to exercise the associated microprocessor ICs while the power to the Boards and the environment within the chamber is appropriately cycled to simulate system testing, installation or normal customer use. During the OLT procedure, each Board periodically reports the status of the associated microprocessor IC to circuitry such as a computer outside the chamber in order to provide a means for determining and recording any failure of a Board.

    Abstract: A device for dynamic signal generation and analysis, which combines an arbitrary waveform generator AWG (3) with a digital signal analysis unit DSAU (23). The two units are interfaced by means of a synchronization unit SU (30), which enables a flexible scheme for controlling how the playback of the waveforms is started as well as synchronizing the recording of the results of the digital signal analysis unit synchronously to specific generated waveforms. The various units of the device are synchronous circuits clocked by a common system clock signal. At least one common numerically controlled oscillator NCO (40) is provided for the arbitrary waveform generator AWG (3) and the digital signal analysis unit DSAU (23).

    Abstract: A test-and-measurement instrument is described. The test-and-measurement instrument can store a state machine. As the state machine is used to analyze a bit stream, breadcrumbs can be saved from states in a memory of the state machine. The breadcrumbs can then be used to analyze the operation of the state machine.

    Abstract: A method for using shared pins in a concurrent test execution environment is disclosed. The method relates to scheduling tests in concurrently executing test flows for automated test equipment (ATE) in a way so that resources can be shared between the test flows. The method comprises determining if any of a plurality of splits used by a first test contains at least one resource that is shared, wherein the first test and a second test are sequenced for execution in two separate concurrently executing test flows. The method further comprises determining if the first test should execute before the second test if the split is associated with resources required by both the second and first tests. Finally the method comprises reserving the split containing the at least one shared resource for access by the first test before beginning execution of the first test.
