    • An embedded test system is provided where asynchronous communications links are used to pass the boundary scan information by the use of a network router to a boundary scan adapter(54, 60) associated with each component to be tested. This approach enables the system components themselves to facilitate the implementation of a chain-free boundary scan architecture as opposed to a traditional boundary scan bridge approach thus reducing component count and simplifying system design. Thus boundary scan tests can still be performed even after one or more components have been disabled, configured in functional mode or have failed. The same commanding sequence can be applied irrespective of the network topology or the component count since the routing of the boundary scan information is the responsibility of the network routing functionality. This testing method is independent of the underlying functionality of the target hardware or its individual components. The invention also provides for a hybrid solution to adapt boundary scan compatible COTS component so that they can be used within a chainless boundary scan architecture.
    • 提供嵌入式测试系统,其中使用异步通信链路通过使用网络路由器将边界扫描信息传递到与要测试的每个组件相关联的边界扫描适配器(54,60)。 这种方法使得系统组件本身能够促进无链边界扫描架构的实现,而不是传统的边界扫描桥接方法,从而减少组件数量并简化系统设计。 因此,即使禁用一个或多个组件,在功能模式下配置或失败,仍然可以执行边界扫描测试。 无论网络拓扑或组件数量如何,都可以应用相同的命令顺序,因为边界扫描信息的路由是网络路由功能的责任。 该测试方法独立于目标硬件或其各个组件的基本功能。 本发明还提供了一种用于适应边界扫描兼容COTS组件的混合解决方案,使得它们可以在无链接边界扫描架构中使用。

    • A scan flip-flop circuit including a data input, a scan input, a data output, a flip-flop, a multiplexer and a delay element is provided. The multiplexer allows selection of either the scan input or the data input for presentation at the input of the flip-flop. The flip-flop provides an output signal at the output of the scan flip-flop. The delay element is in a signal path between the scan input and the input of the flip-flop, and provides a signal propagation delay between the scan input and the input of the flip-flop. The delay between the scan input and the input of the flip-flop is substantially larger than the signal propagation delay between the data input and the input of the flip-flop. The delay in the scan path reduces the need for external buffers to avoid hold-time violations during scan testing of integrated circuits.
    • 提供了包括数据输入,扫描输入,数据输出,触发器,多路复用器和延迟元件的扫描触发器电路。 复用器允许选择扫描输入或数据输入以在触发器的输入处呈现。 触发器在扫描触发器的输出端提供输出信号。 延迟元件在扫描输入和触发器的输入之间的信号路径中,并且在扫描输入和触发器的输入之间提供信号传播延迟。 扫描输入和触发器的输入之间的延迟显着大于数据输入和触发器输入之间的信号传播延迟。 扫描路径的延迟减少了外部缓冲器的需要,以避免集成电路扫描测试期间的保持时间违规。

    • An integrated circuit (IC) comprises a plurality of analog stages (10a-c), each of the analog stages being conductively coupled to a power supply (20; 20a-c), and being conductively coupled to each other by a signal path (12); and a test arrangement for testing the plurality of analog stages, the test arrangement comprising input means such as an analog bus (40) coupled to a signal path input of each analog stage from the plurality of analog stages, output means such as a further analog bus (50) for communicating a test result to an output of the integrated circuit, switching means such as a plurality of switches (36) in the biasing infrastructure of the IC for selectively disabling an analog stage, and control means such a shift register (60) for controlling the switching means. Consequently, the analog stages of the IC can be tested and debugged in isolation without the need for switches in the signal path through the cores. A current sensor (70) may be present in the power supply to facilitate structural testing of the analog stages in isolation.
