  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.

  text: Seamless HW/SW codesign flows support early verification of hardware and Hardware-dependent
    Software (HdS) like drivers, operating systems, and firmware. For early estimation
    and verification, the application of SystemC in combination with Instruction Set
    Simulators and Software Emulators like QEMU is widely accepted. In this article,
    we present an advanced design flow for HW, (RT)OS and HdS refinement and verification
    with focus on the transition from abstract RTOS verification to full system RTOS/HdS
    emulation. In the context of assertion-based verification, we introduce a set
    of generic real-time properties which can be reused and verified at different
    abstraction levels and discuss their application. The properties are presented
    by the means of IEEE standard PSL assertions which are applied for mixed SystemC/HdS
    models.
