    • A system (100) configured to detect faults in signal lines. A system includes a first component (130) configured to communicate with a second component (120) via a signal path including one or more signal traces (112, 114). Sense signal lines (150, 152) are manufactured such that at some point they are in close proximity to a signal trace which is to be monitored. The sense signal lines are configured to use parasitic coupling to redirect a portion of a signal conveyed via a signal trace to a monitoring component (140). The first component is configured to convey a test signal indicative of a type of test via the signal path, and a reference signal (135) to the monitoring component. The monitoring component is configured to utilize the reference signal to ascertain a presence or absence, or characteristics of a received redirected signal. The monitoring component may optionally utilize a locally generated reference signal.
    • 一种被配置为检测信号线中的故障的系统(100)。 系统包括被配置为经由包括一个或多个信号迹线(112,114)的信号路径与第二组件(120)通信的第一组件(130)。 感测信号线(150,152)被制造成使得在某些点处它们处于要被监控的信号迹线附近。 感测信号线被配置为使用寄生耦合来将经由信号迹线传送的信号的一部分重定向到监视部件(140)。 第一组件被配置为经由信号路径传送指示测试类型的测试信号,以及将参考信号(135)传送到监视组件。 监视组件被配置为利用参考信号来确定所接收的重定向信号的存在或不存在或特性。 监视组件可以可选地利用本地生成的参考信号。
