嵌入式系統(tǒng)要求測試工具既能評估單個單元、又能評估整個系統(tǒng)！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(shù)字串行總線、數(shù)字信號處理器、連接存儲器的數(shù)字并行總線、數(shù)字模擬轉(zhuǎn)換器和模擬放大器。 </p> <table class="dateTabel"

盡管嵌入式系統(tǒng)內(nèi)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(tǒng)，部分系統(tǒng)必需相互通信及與外部世界通信(如:I2C，SPI，RS232，RS422，RS485，UART，CAN，LIN，F(xiàn)lexRay，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(tǒng)！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(shù)字串行總線、數(shù)字信號處理器、連接存儲器的數(shù)字并行總線、數(shù)字模擬轉(zhuǎn)換器和模擬放大器。
