摘要摘要混合信号分析仪是在数字示波器和逻辑分析仪的基础上发展起来的一种新型 测试仪器。具有综合分析能力强、成本低、效率高等特点，能够满足高速复杂系 统的信号完整性测试要求，是现代测试系统中不可或缺的综合性测试设备。随着串行总线使用频率的提高，以及实际调试过程的需要，串行总线协议触 发和协议分析模块已经是混合信号分析仪的一个重要组成部分。在触发的方式、 类型、通用性和分析的正确性方面都有了新的要求。针对上述要求，本文以混合信号分析仪的数据处理模块以及几种常用的串行 总线协议为基础，对串行总线协议触发和协议分析模块的设计方案以及实现进行 了详细讨论。围绕如何准确、正确触发，准确、正确分析进行了探索和研究。本文的主要工作内容有：1、串行总线协议触发模块：包括I2C、SPI、CAN、USB等协议的多种触发的 设计。另外，为了实现串行总线协议触发的通用性，设计了自定义的串行 总线协议分析。2、串行总线协议分析模块：包括I2C、SPI、CAN等协议的协议分析模块的设 计。3、为了测试所设计的串行总线协议触发和协议分析功能，进行了能够产生I2C、 SPI、CAN、USB串行总线信号的串行总线协议触发与协议分析测试目标 板的设计。4、硬件调试、模块测试，设计改进。关键词：串行总线，协议触发，协议分析ABSTRACTABSTRACTMixed-signal analyzer is a new test instrument which develops on the basis of digital oscilloscope and logic analyzer. It has the specialties of strong synthetically analyse ability, low cost and high efficiency.Therefore, mixed-signal analyzer can better adapt to the signal integrity test requirements of the high-speed and complex systems. It is an indispensable integrated instrument in the field of modern testing.Along with the serial bus frequency of uses enhancement, as well as the actual debugging processs need, serial bus protocol trigger and the protocol analysis module was already an important part of mixed-signal analyzer. In the trigger way, the type, versatile and the analysis accurate aspect had the new request.Based on the above requests, this paper details the architecture of the serial bus protocol trigger and protocol analysis with the function and implementation of each module, as well as explored resetearch on the correctness and accuracy of serial bus protocol trigger and protocol analysis.The main work in this paper is:Design serial bus protocol trigger module, which includ a variety of types of protocol trigger of I2C、SPI、CAN、USB. In addition, in order to achieve the trigger of the serial bus universal, design a custom serial bus protocol triggermodule.Design serial bus protocol analysis module, which includ a variety of protocol analysis of I2C、SPI、CAN.Design a test goal board which is bal
