摘要

集成电路的平均无故障时间(MTBF)是判断系统可靠性的主要指标,文中提供了一种计算MTBF的有效方法。首先介绍了集成电路失效的一般规律,即满足浴盆曲线的规律;其次分析验证了集成电路的使用寿命问题是满足泊松分布的。基于这两个条件,提出了一种计算集成电路MTBF的算法。根据集成电路74HC00的一组故障时间,计算了其平均无故障时间。验证了所提供方法的可靠性。

Abstract

The mean time of failure of integrated circuits (MTBF) is the main index to determine the system reliability. This paper presents an effective method to calculate the MTBF. In this paper, the general rule of the integrated circuit failure is introduced firstly, which meets the rules of the bathtub curve. The analysis shows that the life of the integrated circuit satisfied the Poisson distribution. Based on these two conditions, an algorithm for computing integrated circuit MTBF is proposed. In this paper, the mean time of failure is calculated according to a set of failure time of IC 74HC0O to verify the reliability of the method.

Key words： bathtub curve; Poisson distribution; failure rate; MTBF
