3 | 1 | Txinto Vaz | We can see the system as a box with inputs and outputs. The system is able to perform one, some of part of a function. Internally, if the work to be done by the system is not trivial, it is divided into subsystems. The system hierarchy is like an inverted tree where each node is a system, being more general and abstract on the top (root) and more concrete and specialized at the bottom (leafs). |

5 | 1 | Txinto Vaz | We will visit some systems: the top most system of our tree (root) and one of the "leaf" nodes. |

7 | 1 | Txinto Vaz | In the root node we can see a mechatronic module, with hardware and software functionalities (and thus, hardware and software inputs and outputs). In the leaf one, pure software functionality and software inputs and outputs. |

15 | 1 | Txinto Vaz | We can see here these things: |

18 | 1 | Txinto Vaz | ** System properties. |
19 | 1 | Txinto Vaz | ** Connectors: J1, J2... |
20 | 1 | Txinto Vaz | *** Numbered pins with assigned flows. |
21 | 1 | Txinto Vaz | * Children view |
22 | 1 | Txinto Vaz | ** Tree view: we can see all the children subtree as a tree-view control, we can expand/collapse nodes, etc... This view also includes connectors and flows. |
23 | 1 | Txinto Vaz | ** First level children. |
24 | 1 | Txinto Vaz | * Function sub systems (or how the functions are "mapped" on this subsystem, to be described later). |
25 | 1 | Txinto Vaz | ** We can see two behaviours satisfied by this system: CULowBeam and BCMParkLights. |
