Temporal Properties in Component-Based Cyber Physical Systems - Appendix

The temporal semantics model represents software as a composed set of componentsC = {c1, c2, . . .}. An implementation of a component consists of a set of behaviors and ports, also called interfaces. Each behavior assigns values to output ports y based on inner states and the values on the input ports u. The sampling ports s and actuation ports z provide a link to the physical environment. Throughout this document we use x as a placeholder for any port, while x(i,j) addresses the j th interface of the component ci. Each component consists of one or more executable units called runnables, which are assigned to schedulable units called a tasks τ . Each occurrences at an interface x is described by a data event x∀k ∈ {1, . . . , n}. An event is defined as the triple x = (
