A novel two-dimensional scan-control scheme for test-cost reduction
— This paper proposes a two-dimensional scan shift control concept for multiple scan chain design. Multiple scan chain test scheme provides very low scan power by skipping many l...

Scan Chain Diagnosis by Adaptive Signal Profiling with Manufacturing ATPG Patterns
—In the past, software based scan chain defect diagnosis can be roughly classified into two categories (1) model-based algorithms, and (2) data-driven algorithms. In this paper w...
