    • An electronic component for failure detection and analysis of bus activity comprises configuration circuitry, a buffer, and read circuitry. The configuration circuitry, the buffer, the read circuitry and the bus being tracked are on the same die. The configuration circuitry identifies one or more modes, one or more triggers, and one or more responses associated with the triggers. The buffer stores transactions on a bus according to the configuration circuitry. The read circuitry reads data from the buffer. A method of tracking bus activity comprises configuring a bus activity tracking component; monitoring an interface for a trigger event; and performing associated responses upon the occurrence of the trigger event.
    • 用于故障检测和总线活动分析的电子部件包括配置电路,缓冲器和读取电路。 被跟踪的配置电路,缓冲器,读取电路和总线位于同一芯片上。 配置电路识别一个或多个模式,一个或多个触发器以及与触发器相关联的一个或多个响应。 缓冲器根据配置电路在总线上存储事务。 读取电路从缓冲器读取数据。 跟踪总线活动的方法包括配置总线活动跟踪组件; 监视触发事件的界面; 以及在触发事件发生时执行相关联的响应。
