摘要

本文提出了利用存储器内建自测试(MBIST)进行专用集成电路(ASIC)内部存储器的单粒子翻转(SEU)检测方法

研究并制定了MBIST的单粒子有效性辐照注量的统计方案

最后在重离子加速器上应用该方法进行了单粒子试验验证.通过与相同结构的存储器SEU结果的对比分析

结果表明

MBIST在有效辐照注量(1.27E+7icons/cm)下

与存储器在标准辐照注量(1E+7icons/cm)下获得的SEU在轨错误率误差小于2倍

运用MBIST方法可以方便、准确地用于评估ASIC的存储器SEU性能指标.

Abstract

This paper presents a new way to evaluate the SEU performance of ASIC internal memory by using Memory-Build-In-Self-Test(MBIST) technology

while an statistical method of effective irradiation dose for MBIST was studied and developed. At last

a SEE verification test was carried out on the heavy ion accelerator by using this method. By comparing with SRAM of the same structure

the results show the error between MBIST(effective irradiation dose 1.27E+7icons/cm)and SRAM (irradiation dose 1.0E+7icons/cm) is less than 2 times

which means the MBIST method can be used for evaluating the SEU performance of ASIC internal RAM conveniently and accurately.
