Abstract : As partially reconfigurable technologies develop for embedded systems, the need for a proper model to describe its behavior emerges. Most academic and industrial tools available on the market does not address dynamic structure modeling. The arising of discrete-event modeling, in particular, Discrete Event System Specification (DEVS), propose formal tools for representing and simulating models. DEVS has already extension which handles the dynamic structure modeling. However, the capacities of these existing formalism have limitations. Notably, they do not address the components context aspect. Also, the existing formalisms have not integrated the system engineering approach. System engineering brings beneficial procedures, notably modeldriven architecture which proposes to separate the system description from its execution target. A platform-specific model is formed from a platformdescription model coupled with a platform independent model. To address these needs, we propose a model description formalism which takes into consideration these two aspects: dynamic structure modeling and system engineering. This formalism is based on DEVS and called Partially Reconfigurable Discrete Event System Specification (PRDEVS). PRDEVS allows to represent dynamic-structure models independently from the simulation platform. The presented approach can be applied to different types of targets, such as software and reconfigurable hardware. This thesis addresses these two kinds of platforms, demonstrating the suitability of the abstract formalism to actual platforms.
