Abstract

Parallel test application helps reduce the otherwise considerable test times in SOCs; yet its applicability is limited by average and peak power considerations. The typical test vector loading techniques result infrequent transitions in the scan chain, which in turn reflect into significant levels of circuit switching unnecessarily. Judicious utilization of logic in the scan chain can help reduce transitions while loading the test vector needed. No performance degradation ensues as scan chain modifications have no impact on functional execution. A computationally efficient scheme is proposed to identify, the location and type of the logic to be inserted. The experimental results confirm the significant reductions in test power possible under the proposed scheme.
