  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: Rapid prototyping based on 3D models is well accepted for several applications.
    This article addresses the application of animated virtual 3D prototypes for the
    development of computer-based systems supporting early collaboration of the system
    designer with the external customer. Our methodology seamlessly integrates illustration
    through 3D animation with the main tasks of computer-based real-time systems development,
    i.e., implementation and verification. The approach is outlined by the example
    of the design of a flexible manufacturing system.

  text: This article introduces and discusses different innovative means for visual
    specification and animation of complex concurrent systems. It introduces the completely
    visual programming language Pictorial Janus (PJ) and its application in the customer-oriented
    design process. PJ implements a completely visual programming language with inherent
    animation facilities. The article outlines the transformation of purely visual
    PJ programs into textual imperative programming languages. The second part of
    the article investigates animated 3D-presentations and introduces a novel approach
    to an animated 3D programming language for interactive customer-oriented illustrations.
