摘要 胚胎硬件的容错策略是影响阵列可靠性的重要因素,可靠性分析可从理论上得到理想的容错策略和阵列布局,为硬件优化设计提供目标.胚胎硬件可靠性分析的传统模型仅考虑阵列布局结构,视细胞为固定节点,不考虑容错电路设计中细胞内部电路模块的变化,未能全面反映电路设计的实际情况.针对这一不足.提出了新的可靠性模型,将细胞内配置存储器和输入输出布线器电路的变化情况引入到建模过程中,经过实例仿真分析,总结出了基于可靠性分析的容错策略选择方法和分析步骤,给出了可指导如何选择容错策略选择的量化条件. Fault-tolerant strategy is one of the most important e^ects on the reuaoni^y ol emuLyulu,~ hardware. The best fault-tolerant strategy and array layout could be derived from reliability analysis. The traditional reliability model of embryonics hardware was based only on the layout of the array, all cells in the structure were treated as fixed nodes, and the changes of the cell modules in circuit realization were not considered. In this article, a new model was presented with the configuration memory and the I/0 routing switch which would change in different fault-tolerant strategies. According to a case study, the methods and procedures in selecting fault-tolerant strategy were summarized. Lastly, the specific quantitative selection criteria based on the example was obtained, and could be directly used to guide the selection of fault-tolerant strategy.
