    • A method of testing for power and ground continuity of a semiconductor device having Input and Output (IO) pins and at least a pair of power and ground pins includes identifying the power and ground pins of the device. A victim pin is selected from the IO pins of the device for each pair of the power and ground pins, and an aggressor pin for each victim pin is selected from the remaining IO pins. The aggressor pins are toggled between a high state and a low state. A level of switching noise on each victim pin is measured, and the measured levels of switching noise are compared with predetermined data to determine power and ground continuity of the device.
    • 一种测试具有输入和输出(IO)引脚和至少一对电源和接地引脚的半导体器件的功率和接地连续性的方法,包括识别器件的电源和接地引脚。 从每个电源和接地引脚的器件的IO引脚中选择受害器引脚,并从其余的IO引脚中选择每个受害引脚的引脚。 侵略者引脚在高状态和低状态之间切换。 测量每个受害者引脚上的开关噪声水平,并将测量的开关噪声电平与预定数据进行比较,以确定器件的功率和接地连续性。

    • A load board includes an embedded relay tracker circuit that counts and stores relay clicks to measure relay usage. Having accurate relay usage data reduces maintenance costs. The relay tracker circuit includes a controller with a counter for counting relay clicks of the load board relays and wires or conductive traces connecting the controller to the relays. Each time a relay switches, a signal is transmitted from the relay to the controller and the controller increments the counter. The count information then is stored in a memory connected to the counter.
    • 负载板包括嵌入式继电器跟踪器电路,其计数并存储继电器点击以测量继电器使用。 具有精确的继电器使用数据可以降低维护成本。 继电器跟踪器电路包括具有用于计数负载板继电器的继电器点击的计数器的控制器,以及将控制器连接到继电器的导线或导电迹线。 每次继电器切换时,信号从继电器传输到控制器,控制器递增计数器。 然后将计数信息存储在连接到计数器的存储器中。
