摘　　要：大型物理实验中电子学逻辑经常需要在线升级,现场可编程门阵列器件(FPGA)的大量使用使得在线升级成为可能。介绍了一种通过串行Flash和复杂可编程逻辑器件(CPLD)采用被动串行模式(PS)配置FPGA芯片的方案,可以实现电子学系统的上电自动配置、远程更新配置文件和系统运行模式的切换。给出了方案的基本原理、系统框图和硬件电路。Online upgrade of electronics system is usually needed in big physics experiment. It becomes possible because of universal use of Field Programmable Gates Array （FPGA）. This paper introduces a scheme that a serial Flash and a Complex Programmable Logic Device （CPLD） is used to configure FPGA by passively serial mode （PS）. The goal is achieved that is the auto configuration after power reset and the remote online upgrade and the function switch of electronics system. The rationale, system frame and hardware circuit of the scheme is also given.
