A novel approach for simultaneous reduction of shift and capture power for scan based testing

摘要

This paper proposes a novel approach for reducing the shifting and capture power by a fan-out aware modified adjacent X-filling technique. This approach reduces the time complexity and number of iterations in addition to the reduction of test power. Experimental results obtained from ISCAS'89 circuits are compared with existing techniques prove that the proposed ATPG methodology is suitable to test the scan based system-on-chip architecture with reduced testing power.
