集成电路装置及用于产生电力迹线的方法
摘要：
本申请案涉及集成电路装置及用于产生电力迹线的方法。包含于具有多个电力域的系统(例如，微控制器系统)中的电力迹线端口包含输出指示所述电力域的状态的数字信号的电力迹线端口。如果每一电力域独立于在所述系统中的其它电力域，那么每一电力域可在所述电力迹线端口中具有其自身的一组电力迹线引脚，所述电力迹线引脚至少部分在系统之外。如果电力域具有多个状态，那么可使用多个引脚来指示所述多个状态。在一些实施方案中，所述电力迹线端口可包含用于提供性能水平信号的性能水平引脚。所述电力迹线端口可耦合到在所述系统之外的电力分析器的电力迹线探针，所述电力迹线探针用于产生电力迹线。
摘要（英）：

A power trace port included in a system (e.g., a microcontroller system) having multiple power domains includes a power trace port that outputs digital signals indicating the states of the power domains. If each power domain is independent of other power domains in the system, each power domain can have its own set of power trace pins in the power trace port that are at least partially external to the system. If a power domain has multiple states, multiple pins can be used to indicate the multiple states. In some implementations, the power trace port can include performance level pins for providing performance level signals. The power trace port can be coupled to power trace probes of a power analyzer that is external to the system for generating power traces.
