13. MAGILLEM Tool TLM Level: - Bus Interface, components creation, component connection: Graphical Mode (Eclipse plugin). SystemC code generation: - The generated SystemC code is comprehensible by an individual but it corresponds to a “skeleton” of the platform hardware. - Inter-connects are taken into account during the generation of the SystemC code. 13Workshop - November 2011

14. Graphical Interface 14Workshop - November 2011

15. SystemC code generation 15Workshop - November 2011

16. SPEAR Tool 16Workshop - November 2011

17. TLM Simulation 17Workshop - November 2011

18. SystemC/TLM advantage 18Workshop - November 2011 TLM Level: Rapid prototyping Check the data stream mining (optimization) Integrate HW and SW Models SystemC code generation The generated SystemC code is comprehensible by an individual. The OSCI TLM standard is available now and is already in use, and it should foster the development of the TLM IP ecosystem.
