“…Modelers are faced with additional trade-offs regarding bus usage, such as reducing visual complexity and ease of bulk element manipulation versus the loss of visual information and the risk of bundling logically unrelated signals. In addition, modelers have to organize buses (i.e., ordering and nesting of signals and choosing start and endpoints) to avoid buses that are too "clunky" (Jaskolka et al 2021).…”

Matlab/Simulink is a graphical modeling environment that has become the de facto standard for the industrial model-based development of embedded systems. Practitioners employ different structuring mechanisms to manage Simulink models' growing size and complexity. One important architectural element is the so-called bus, which can combine multiple signals into composite ones, thus, reducing a model's visual complexity. However, when and how to effectively use buses is a non-trivial design problem with several trade-offs. To date, only little guidance exists, often applied in an ad-hoc and subjective manner, leading to suboptimal designs. Using an inductive-deductive research approach, we conducted an exploratory survey among Simulink practitioners and extracted bus usage information from a corpus comprising 433 open-source Simulink models.We elicited 22 hypotheses on bus usage advantages, disadvantages, and best practices from the data, whose validity was later tested through a confirmatory survey. Our findings serve as requirements for static analysis tools and pave the way toward guidelines on bus usage in Simulink.
