Framework for mixed systems

In this paper, we present the F4MS (Framework for Mixed Systems) which is a Computer Aided Design for software and hardware design, simulation and aided execution. Based on components which could be software or/ and hardware, as well as all operational tools. This framework is an extension of the TI4CS framework (Tools Integration for Complex Software), witch deals only with softwares components. In order to design a mixed systems in this framework we use a general model (execution graph), which characterizes the integration phase in the design methodology. This methodology also covers specification and partitioning phases. Finally, to illustrate this work we propose an example of mixed system for the implementation of the VPN solutions.
