因为最新研发的250块ALICE/PHOS前端电子学FEE系统板的部分器件在无铅焊接中被部分或完全损坏.为了不影响FEE系统性能,准确定位FFE系统板上与FPGA相关的故障,在对ACEX系列FPGA的配置机制进行深入研究的基础上找到了一种定位FEE系统板故障点的方法.文章着重研究了多器件的JTAG配置、基于EPC系列配置器件的PS配置和FPGA的自动重配置等问题.FEE系统板的大量测试和维修结果证明,该定位方法能准确、快速地定位FEE系统板上与FPGA器件相关的故障点.

Since some devices on the latest developed 250 ALICE/PHOS Front-end electronics(FEE) sys-tem cards had been partly or completely damaged during lead-free soldering. To alleviate the influence on the performance of FEE system and to locate fault related FPGA accurately, we should find a method for locating fault of FEE system based on the deep study of FPGA configuration scheme. It emphasized on the problems such as JTAG configuration of mult-deviees, PS configuration based on EPC series configu-ration devices and auto re-configuration of FPGA. The result of the massive FEE system cards testing and repairing show that that location method can accurately and quickly target the fault point related FP-GA on FEE system cards.
