DFR also has three key components: 1) technology design, 2) chip design (logical and physical), and 3) system design. In each of the three, the DFR work must strive for defect tolerance. In the case of technology design, leakage-induced power mitigation maintains an edge in importance over defect tolerance. Regarding chip design and DFR,
