Transmission Systems Prototyping Based on Stateflow/Simulink Models

In this paper we describe an efficient methodology for rapid prototyping of data transmission systems based on Stateflow/Simulink models using a multi-level system development and testing approach. Transmission systems incorporate multi-domain functions and algorithms, i.e. physical layer circuits and communication protocol controllers. The Stateflow/Simulink environment enables the development of precise simulation models that include signal and protocol processing units. The proposed prototyping methodology is based on the progressive translation of high-level model blocks into hardware/software modules of the prototype architecture using custom and/or automated code generation tools. A custom data exchange and synchronization interface between the Stateflow/Simulink workspace and the circuit modules enables the integration of the simulation model and the prototyping platform into a complete functional system. The application of the proposed methodology in the development of an ADSL modem in a custom prototyping platform is also described
