摘要
The designing process of modem electronic systems demands high system reliability and maintainability. In order to perform fault detection, localization and isolation effectively, it is necessary to design a Built-In Self-Testing (BIST) module specific for the corresponding system. This paper presents a BIST method based on the compressed 2-dimensional signature analysis. The principle of compression and performance of test are discussed in detail. Using the presented method, a high Faulty Coverage Ratio (FCR) can be achieved with a short signature compressed in both time domain and space domain. Theoretical analysis shows that this method is reliable and it can be easily implemented in hardware.
