An apparatus and method for soft-error resilience or correction with the ability to perform a manufacturing test operation, a slow-speed snapshot operation, a slow-speed signature analysis operation, an at-speed signature analysis operation, a defect tolerance operation, or any combination of the above operations. In one embodiment, an apparatus includes a system circuit, a shadow circuit, and an output joining circuit for soft-error resilience. The output joining circuit coupled to the output terminals of the system circuit and the shadow circuit includes at least an S-element for defect tolerance. In another embodiment, an apparatus includes a system circuit, a shadow circuit, a debug circuit, and an output joining circuit for soft-error correction. The output joining circuit coupled to the output terminals of the system circuit, the shadow circuit, and the debug circuit includes at least a V-element for defect tolerance. |
