Abstract :
In the paper a method of the fault detection, identification and localization by means of a ring LFSR is presented. The properties of a ring LFSR and the method to design a ring LFSR BIST is also given. Practical examinations of a ring LFSR application for localization faults in 8,16,24 and 32-bit buses are presented. Some important observations regarding the types of characteristic polynomials used in ring LFSRs are also included. Finally, the obtained results are summarised.
