Scan testing dynamic power consumption can induce reliability problems in the circuit under test (CUT) during manufacturing testing. In this paper, we propose a scan chain partitioning technique, supported by a scan hold mechanism, for low power dissipation during the shift phase of the scan testing procedures. Substantial power reductions can be achieved either in built-in self test (BIST) or non-BIST scan-based testing environments, without test application time increase, fault coverage decrease, scan cell reordering and clock gating.
