摘要
基于物理层波形的串行通信测试方法是通过对物理层波形的采样并分析得到数据链路层数据。根据CAN总线和RS232的协议结构,各数据域的前后相关且状态有限,采用有限状态机对数据流进行扫描分析可实现数据的快速处理。
The test method of serial communication based on physical layer wave shape is gaining the data link layer by sampling and analyzing physical layer wave shape. According to the protocol structure of CAN bus and RS232, the relation-ship and station of each data field is limited. Searching and analyzing the data stream by Finite-state Machine （FSM） can make data immediate processing available.
