    Co-Simulation of Hardware and Software in Palladio
    (Softwaretechnik-Trends Band 43, Heft 1, 2023) Weber, Sebastian; Henss, Jörg; Reussner, Ralf
    To ensure the fulfilment of quality requirements, for example performance, at design time, the software architect can model the software and simulate it with Palladio. The accuracy of the model depends on the estimation of resource demands, which is difficult and error prone. Therefore, in the later stages of development, values should be evaluated based on available information instead of being estimated. An unavailable component implementation or delayed hardware access should not force the software architect to stick with the estimation, but be compensated otherwise, for example with prototypes or hardware simulation. This paper presents six approaches to adapt the evaluation of hardware resource usage in the Palladio software architecture simulation by incorporating co-simulation techniques to compensate different shortcomings. Possible usage scenarios of the approaches are presented and put in relation to the estimated development effort. We present our initial results of implementing one of the approaches, the integration of a hardware-simulation-based resource demand estimation in Palladio. It can compensate unavailable hardware, despite hardware specifications and software being available. The results show that the parameterization options of the hardware simulation were not sufficient to achieve the desired accuracy and the simulation time increases significantly.
