飞行器FPGA检测点优化设置方法

,针对诱发宇宙空间环境下航空航天飞行器工作异常和故障的FPGA单粒子效应,分析了FPGA电路的特点,从空间和时间维度上,提出基于“运算单元 存储器/触发器”进行FPGA电路层次模块的划分;结合节点所在位置的重要性、节点与其它节点的关联程度以及节点本身的单粒子软错误翻转概率,提出了重要度分析模型,从而建立基于重要度排序的对测试点设置优化方法。测试实验表明,该方法是一种可行的检测点优化设置方法。

FPGA Testing Points Optimization Method for Aerospace Vehicle

Arming at the aerospace vehicle abnormal and failure cause by FPGA single particle effect in the space environment, the FPGA circuit is devised some levels with "computing unit + memory/trigger" via analyzing the characteristics of the FPGA circuit based on space and time dimension . Combined with the location importance, the connection degree among the nodes and the nodes'' own soft error probability, an importance analysis model is proposed. And then the testing points are optimized based on the importance of each node using the proposed importance analysis model. The test results indicate that the method is a feasible optimization method.
