State-Sensitive X-Filling Scheme for Scan Capture Power Reduction
Jing-ling Yang, Qiang Xu · IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems · 2008
Based on the operation of a state machine, this paper elucidates a comprehensive frame for probability-based primary-input-dominated X-filling methods to minimize the total weighted switching activity (WSA) during the scan capture operation. Experimental results demonstrate that the proposed approach significantly reduces both average and peak WSAs.
