In this paper, we introduce FoRTReSS (Flow for Reconfigurable archiTec-tures in Real-time SystemS), a methodology for the generation of partially re-configurable architectures with real-time constraints, enabling Design Space Exploration (DSE) at the early stages of the development. FoRTReSS can be completely integrated into existing partial reconfiguration flows to generate physical constraints describing the architecture in terms of reconfigurable re-gions that are used to floorplan the design, with key metrics such as partially reconfigurable area, real-time or external fragmentation. The flow is based upon our SystemC simulator for real-time systems that helps develop and validate scheduling algorithms with respect to application timing constraints and partial reconfiguration physical behaviour. We tested our approach with a video stream encryption/decryption application together with Error Cor-recting Code and showed that partial reconfiguration may lead to an area IThis document is a collaborative effort. ∗Corresponding autho
