| 摘 要： | 在现代电子系统的设计过程中,由于对系统的可靠性和可维护性要求越来越高,因此必须针对具体情况设计相应的内建自检(built-in self-testing,BIST)模块,从而保证系统能够进行准确的故障检测和故障定位与隔离.提出了一种基于两维压缩特征字分析的BIST方法,就其压缩原理和检测性能进行了详细分析.分析结果表明,通过时域和空域的两维压缩,可以用较短的特征字实现高故障覆盖率.该方法简单可靠,便于硬件实现.

| Abstract: | The designing process of modern electronic systems demands high system reliability and maintainability. In order to perform fault detection, localization and isolation effectively, it is necessary to design a BIST (built-in self-testing) module specific for the system. This paper presents a BIST method based on 2-dimensional-compressed signature analysis. The principle of compression and performance of test are discussed in detail. With a short signature compressed 2-dimentionally both in time domain and space domain, this method can achieve a high faulty coverage ratio. Theoretical analysis shows that this method is reliable and easy to be implemented in hardware. |
