As can be seen from Description 3.2, the simulation-flow-model consists of three additional declarations compared to a bare model. The tool-flow defines the sequence of simulation tools which are to be executed and the output-mapping selects specific outputs of simulation tools to be associated with output ports of the simulation-flow-model. The directory-identifier defines the name of the sub-directory which will be used as the root directory for evaluations of the simulation-flow-model.
