基于动态部分重配置技术的自动测试系统研究

The Application of Dynamic Partial Reconfiguration in Automation Test System

摘要:

为了在不中断自动测试系统运行的情况下,将实现不同测试功能的比特流文件下载到其板载FPGA中,对动态部分重配置技术进行了研究；研发了一套基于CPCI架构的测控应答机自动测试系统；自动测试系统利用动态部分重配置技术和PCI总线技术,由主控计算机软件将满足不同测试需求的部分重配置比特流文件通过PCI总线动态下载到板载FPGA中,且不影响测试系统的正常运行；测试表明利用动态部分重配置技术,自动测试系统可以将以往需要多块板卡才能实现的功能集成到一块板卡中,大大增加了系统的集成度,并有效降低了系统的硬件成本,同时也能够使自动测试系统具备在线升级功能,增加了系统的设计灵活性。

Abstract:

In order to download different bitstream files to automation test system FPGA without interrupting it’s normal operation, a new dynamic partial reconfiguration technology is introduced and a CPCI TT C transponder automation test system is developed based on it. The system master computer software can download partial reconfiguration bitstream files which can realize different test functions to FPGA by PCI bus, when the system is running. The test result shows that many traditional cards can be replaced by a card with partial reconfiguration technology in this automation test system. The system has higher integration, lower hardware price, more design flexibility and online upgrading function.
