Xilinx FPGA抗辐射设计技术研究

Radiation Hardness Research on Xilinx FPGA

针对Xilinx FPGA在航天应用中的可行性,文章分析了Xilinx FPGA的结构以及空间辐射效应对FPGA的影响,结合实际工程实践给出了提高其可靠性的一些有用办法和注意事项,如冗余设计、同步设计、自检等。表明配置信息的周期刷新和三模冗余设计是减轻单粒子效应的有效方法。

For the application possibility of Xilinx FPGA in aerospace field,this paper analyzes the structure of Xilinx FPGA and the impact of space radiation on FPGA,proposes some useful ways and points for attention to improve its reliability on the basis of engineering practice,such as redundancy design,synchronization design,self-check,etc.The periodic refreshing to express installing information and the design with three mold redundancies are the effective methods that reduce a series of single event effects.
