    Multi-level Hardware Simulation in Palladio
    (Softwaretechnik-Trends Band 43, Heft 4, 2023) Weber, Sebastian; Taghavi, Bahareh
    Predicting the fulfillment of quality requirements, e.g., performance, is important during design and implementation of a software system to ensure its implementation can meet these requirements. Model-based analysis is a common approach to get such predictions. It usually requires a trade-off between the accuracy of the result and the execution time of the analysis, because resources for the execution of the analysis are limited, but some components might require a more accurate analysis. When looking at traditional model-based analyses, like the Palladio approach, the user can decide this trade-off and with it the level of granularity of the model and simulation only prior to, but not throughout, the simulation execution. In addition, the complexity and heterogeneity of systems is increasing which complicates modelling and analysis on a single level further. This paper presents a concept for the extension of the Palladio approach to support modelling and analysis of systems on multiple levels of abstraction to overcome these limitations.

    A Survey of Analysis Composition Operators in the Context of Palladio
    (Softwaretechnik-Trends Band 43, Heft 4, 2023) Taghavi, Bahareh; Weber, Sebastian
    Model-Based Analysis is an approach in Model-Driven Engineering that uses models to systematically analyze a system for structure, behavior, or quality characteristics. Due to the complexity and interdependence of modern systems, individual analysis approaches need to be combined to meet a specific purpose and achieve complete analysis. This paper provides an overview of current analysis composition operators in the context of Palladio, along with examples of how they are used. The objective is to define some criteria that aid in the judicious selection of the most fitting operator for distinct scenarios.
