    Model: csmacdPrism.imi
    Mode: Parametric deadlock-checking.
    The cartography will be drawn.
    The result will be written to a file.
    The trace set(s) will be generated in a graphical mode.
    Description of states will be output.

    Final constraint such that the system is deadlock-free:
    False
