Over the past decade, with increasing advancements in technology, low-power design has become one of the most focused areas. Technology goes decreasing and the number of functionalities on a single IC increases. Process variations play a huge role during fabrication of devices with low feature sizes. Low-power design techniques pose a number of challenges during the design phase as well as the testing phase. One of the most commonly used technique for power reduction is using multi-voltage domains on the chip where each block can work at different supply voltages irrespective of the other blocks. Testing these designs implies testing at all operational voltages to ensure 100% fault coverage. The disadvantage of this brute-force solution is in the greatly increasing test cost and the test time. This research is focused on analyzing fault models and their behavior in multi-voltage power supplies and reducing test cost by suggesting a single test voltage for the fault models considered. Logical and temporal fault are considered in this work. Simulations are done using standard circuits that are designed using a 45nm technology with defects injected into them. The results obtained give a solid conclusion in the voltage that is to be used for maximum fault coverage.
