| 摘 要： | 星载计算机系统处于空间辐照环境中，可能会受到单粒子翻转的影响而出错，三模冗余就是一种对单粒子翻转有效的容错技术。通过对三模冗余加固电路特点的分析，提出了在ASIC设计中实现三模冗余的2种方法。其一是通过Syno—psys的综合工具DesignCompiler对原设计进行综合，然后修改综合后的门级网表再次综合；其二是直接建立采用三模冗余加固的库单元。

| Abstract: | The satellite-borne computer system in the radiation space may make mistakes because of the single event upset （SEU）. The triple modular redundancy （TMR） technology is a kind of fault-tolerant technique effective on SEU. Through analyzing the characteristics of the TMR reinforce circuit, two methods to realize the TMR in the ASIC design is proposed. One is to synthesize the original design by the synthesis tool DesignCompiler of Synopsys and modify the netlist, and then synthesize it again. Another is to establish the library cells which is reinforced by TMR technology. |
