Error identification and data retrieval in signature analysis based data compaction
Xiaoling Sun, W. Tutak · 2002
A novel multiple error identification and data retrieval technique for multiple input shift register (MISR) based signature analysis environment is presented. Utilizing existing BIST resources and using a second MISR, it is capable of identifying any number errors in an input data stream and fully recovering the information lost during signature compaction. The application of this technique in a IC level fault diagnosis scheme is given.
