    • Method and device for determining the absence of voltage in electrical equipment. An installed device is electrically connected to a power source. The installed device has circuitry capable of detecting voltage, performing self-diagnostics, and testing for connectivity to the power source. In one embodiment, the device can also check to see if the voltage is at a deenergized level, recheck for continuity and repeat the self-diagnostics. In another embodiment, the installed device can be electrically connected to the line and load side of a disconnect and have circuitry configured to check the status of the disconnect. In another embodiment, the device can be configured to communicate with a portable reader in order to transfer information to the portable reader. In yet another embodiment, the device can be configured to interact with a controller that controls access to the panel in which the device is installed.

    • This disclosure describes an integrated circuit with self-test features for validating functionality of external interfaces. Example external interfaces include memory interfaces and bus interfaces, such as a peripheral component interconnect (PCI) bus, an advanced high-performance bus (AHB), an advanced extensible interface (AXI) bus, and other external interfaces that operate a high frequency, e.g., 200 MHz or greater. Test logic may be embedded on the integrated circuit and configured to validate functionality of external interfaces while receiving power and non-test signals from external test equipment. Thus, external test equipment may not supply high frequency test signals to the integrated circuit. The external test equipment may, however, independently validate functionality of a pin interface of the integrated circuit. As a result, the integrated circuit may reduce cost and time required to verify functionality and timing of the external interfaces.
    • 本公开描述了具有用于验证外部接口的功能的自检特征的集成电路。 示例外部接口包括存储器接口和总线接口,例如外围组件互连(PCI)总线,高级高性能总线(AHB),高级可扩展接口(AXI)总线和其他操作高频率的外部接口, 例如,200MHz或更大。 测试逻辑可以嵌入在集成电路中,并被配置为在从外部测试设备接收电力和非测试信号的同时验证外部接口的功能。 因此,外部测试设备可能不会向集成电路提供高频测试信号。 然而,外部测试设备可以独立地验证集成电路的引脚接口的功能。 结果,集成电路可以降低验证外部接口的功能和定时所需的成本和时间。
