嵌入式系統要求測試工具既能評估單個單元、又能評估整個系統！如圖所示，典型MP3音樂播放器的方框圖。象許多嵌入式計算設備一樣，MP3播放器使用混合信號，其中包含各種數字串行總線、數字信號處理器、連接存儲器的數字并行總線、數字模擬轉換器和模擬放大器。

盡管嵌入式系統內部常用的許多技術都存在既定的標準，但主要測試要**保證所有單元同步，作為無縫集成的整體運行。終端設備可能會包含多個嵌入式系統，部分系統必需相互通信及與外部世界通信(如:I2C，SPI，RS232，RS422，RS485，UART，CAN，LIN，FlexRay，并行等)。這是集成測試的延伸，以保證綜合功能、定時操作和通信。這一領域要求測試工具既能評估單個單元、又能評估整個系統！如圖所示，典型MP3音樂播放器的方框圖。象許多嵌入式計算設備一樣，MP3播放器使用混合信號，其中包含各種數字串行總線、數字信號處理器、連接存儲器的數字并行總線、數字模擬轉換器和模擬放大器。
