  text: Refinement of untimed TLM models into a timed HW/SW platform is a step by
    step design process which is a trade-off between timing accuracy of the used models
    and correct estimation of the final timing performance. The use of an RTOS on
    the target platform is mandatory in the case real-time properties must be guaranteed.
    Thus, the question is when the RTOS must be introduced in this step by step refinement
    process. This paper proposes a four-level RTOS-aware refinement methodology that,
    starting from an untimed TLM SystemC description of the whole system, progressively
    introduce HW/SW partitioning, timing, device driver and RTOS functionalities,
    till to obtain an accurate model of the final platform, where SW tasks run upon
    an RTOS hosted by QEMU and HW components are modeled by cycle accurate TLM descriptions.
    Each refinement level allows the designer to estimate more and more accurate timing
    properties, thus anticipating design decisions without being constrained to leave
    timing analysis to the final step of the refinement. The effectiveness of the
    methodology has been evaluated in the design of two complex platforms.
