Testable design techniques for systolic motion estimators based on M-testability conditions are proposed in this paper. The whole motion estimator can be viewed as a two-dimensional iterativelogicarray (ILA) of processing elements (PEs) and multiplying elements (MULs). The functions of each processing element and multiplying elements are modified to be bijective to meet the M-testable conditions...
Owing to the rapid advance in semiconductor fabrication technology, a large number of transistors can be incorporated onto a single chip. However, this will reduce the controllability and observability of the chip significantly. Consequently, testing such highly complex and dense circuits becomes very difficult and expensive. Therefore, we propose an efficient design-for-testability technique based...
