Dynamic Partial Reconfiguration (DPR) in reconfigurable platforms can be used for the mitigation of aging-related permanent faults. We propose an application-specific system-level design methodology for determining the appropriate number of Partially Reconfigurable Regions and their compatibility with Partially Reconfigurable Modules for maximizing the system lifetime. Specifically, we propose a lifetime-aware scheduler that maximizes system MTTF. We use the scheduler along with an automated floorplanner for design space exploration at design-time to generate a heterogeneous PRR system. Our experiments show that the heterogeneous systems can offer up to 2x lifetime improvement over homogeneous ones.
