Some Burning Issues that Justify Power-Aware DFT

There is no question that awareness of power dissipation during testing is essential. In fact, there are many levels of awareness with respect to power: Measuring power during functional test; Managing power during structural test; Testing the power management features; Testing despite the power management features The first two fall into the category of managing the high- power aspects of testing; the next two are pertinent to the need to test the low-power aspects of a design. All of these dimensions have an impact on power-aware DFT.
