Low-power scan design using first-level supply gating.

Low-power scan design using first-level supply gating.

Reduction in test power is important to improve battery lifetime in portable electronic devices employing periodic self-test, to increase reliability of testing, and to reduce test cost. In scan-based testing, a significant fraction of total test power is dissipated in the combinational block. In th...
