【摘要】 MCU系统中各种外围电路和接口电路使其具有强大的智能化控制能力,因此MCU的功能测试工作也极其复杂。在传统的MCU模块功能测试中,从连接评估板、启动调试工具、下载并执行测试程序、到连接引脚及连接测试仪器都需要工程师的手动操作。为了减少模块功能测试过程中的人为干预,提高测试的自动化能力,本文研究并提出MCU模块的自动化功能测试系统。论文从系统论述自动化功能测试系统的工作机理开始,按照系统实现流程,深入研究了系统的整体解决方案。然后分别讨论了自动控制环境(JAZZ)在系统中的测试流程控制、测试仪器控制作用,以及实现引脚内部自动连接的FPGA设计,并且通过制定系统内MCU与FPGA之间的握手机制,最终实现了MCU模块的自动化功能测试系统。结果证实本系统的设计方案成功实现了MCU模块功能测试过程的自动化。与传统的MCU模块功能测试方法相比,本文提出的自动化的功能测试系统减少了人为干预,大大缩短了测试时间,提前了产品的上市时间,给公司带来更大的收益。更多还原

【Abstract】 MCU has powerful intelligent control ability because of its various kinds of peripherals and interface circuits, so it is very important to verification and test. In traditional validation methodology, not only connecting evaluation board to PC, connecting debugging tools, downloading testcases into on-chip flash or sram, but also executing, debugging testcases, connecting external pins and testing instruments are all need to be operated namually by engineers. On the purpose of reducing human intervention and achieving automatic test as possible, this paper presents an automatic functional testing system for MCU modules. This thesis discusses from the working mechanism of automatic functional testing system, and further researches the solution according to realization flow. Afterward, discusses the functions of automatic control environment JAZZ in system which plays roles in controlling test flow and test instrument, and FPGA development which plays a role in automatic connecting pins, as well as handshake mechanism between MCU and FPGA. Finally realizes the automatic module’s functionality test system. it is proved that automatic functional test for MCU modules is successful realized. It is proved that automatic functional test for MCU modules is successful realized. Compared with traditional testing method of MCU modules, automatic module functional testing system reduces human intervention and testing time, and shortens the time of products approaching market. , so brings more benefit to company.更多还原
