This paper discusses a low-power test scheme compatible with both test compression and built-in self-test environments. The key contribution is a detailed analysis showing that a simple power-aware controller may allow significant reductions of toggling rates when feeding scan chains with either decompressed test patterns or pseudorandom vectors. While the proposed solution requires minimal modifications of existing DFT logic, its use results in a low switching activity during all phases of… CONTINUE READING
