SRAM型FPGA单粒子效应敏感性分析研究

摘要

首先描述了典型的SRAM型FPGA内部通常包含的三类基本资源,并分析三类基本资源内部不同功能的电路单元对单粒子效应的敏感性,归纳出Virtex系列SRAM型FPGA中6种类型的单粒子效应敏感结构单元,并得出这些敏感结构单元的单粒子翻转、单粒子功能中断、单粒子闩锁的检测方式,最后对SRAM型FPGA单粒子效应评估研究的发展趋势做了简要总结.%First, it describes a typical SRAM ?based FPGA which usually contains three basic internal re sources, and analyzes the single event effect (SEE) sensitivity of the circuit elements with the different func tions of three basic internal resources, and second summarizes six types of sensitive structural elements on VI- TEX series SRAM - based FPGA and comes to several kinds of test procedure of SEU, SEFI, SEL of those sensi tive structural elements. Finally gives a brief summary on SRAM - based FPGA SEE evaluation trends.
