Sažetak
This paper proposes a new DFT Architecture that contains three test scan modes. The test data could be interval broadcast to scan chains whenever the data in corresponding locations are compatible. Compared with the conventional broadcast scan architecture, the proposed architecture achieves better compression ratio in all cases, and the test application time is also induced. The hardware overhead is very low. Both theoretical and experimental results prove efficacy and versatility of the proposed scheme.
