A novel reseeding technique for accumulator-based test pattern generation

X. Kavousianos, D. Bakalis, D. Nikolos
2001 Proceedings of the 11th Great Lakes Symposium on VLSI - GLSVLSI '01  
In this paper we present a novel reseeding technique for accumulator-based Test Pattern Generation suitable for circuits with hard-to-detect faults.  ...  The proposed technique achieves complete fault coverage with shorter test sequences and requires less hardware for its implementation than the corresponding already-known techniques.  ...  PROPOSED ARCHITECTURE The accumulator is utilised as a test pattern generator for testing blocks physically connected to it. The architecture of the proposed TPG is shown in Figure 1 .  ...
