Abstract基于SRAM工艺的FPGA在空间环境下容易受到单粒子翻转(Single Event Upsets,SEU)的影响而导致信息丢失或功能中断.在详细讨论三模冗余(Triple Modular Redundancy,TMR)和刷新(Scrubbing)的重要原理及实现细节的基础上,实现了一种高可靠性、TMR+Scrubbing+Reload的容错系统设计,用反熔丝型FPGA对SRAM型FPGA的配置数据进行毫秒级周期刷新,同时对两个FPGA均做TMR处理.该容错设计已实际应用于航天器电子系统,可为高可靠性电子系统设计提供参考.
Other AbstractAerospace and extra-terrestrial applications on SRAM FPGA are sensitive to SEU which might result in information loss or functional interruption.In this paper,a detailed introduction to TMR and Scrubbing,which are the significant techniques of this design,was given;then,a highly reliable fault-tolerant system based on TMR,Scrubbing and Reload rules was implemented.An anti-fuse FPGA periodically scrubbed the configuration bitstream of SRAM FPGA in milliseconds level,and both FPGAs implemented triple module design redundancy.This fault-tolerant design has been adopted in an actual spacecraft electronic system,which can make reference to the design of highly reliable electronic systems.
