Use-case modelling to describe system environments, user scenarios, and test cases. UML has support for object-oriented system specification, design and modelling. Growing interest in UML from the embedded systems and realtime community. Support for state-machine semantics which can be used for modelling and synthesis.
An embedded system on a plug-in card with processor, memory, power supply, and external interfaces. An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.
Model-based design (MBD) is a mathematical and visual method of addressing problems associated with designing complex control, [1] signal processing [2] and communication systems. It is used in many motion control , industrial equipment, aerospace , and automotive applications.
Time: This chapter defines a rich model of time that supports both the definition of physical and logical time properties;. [4] It comes with a companion language called CCSL defined as an annex. Generic Resource Modeling: This chapter offers extensions required to model a general platform for executing real-time embedded applications;
The first known prominent public usage of the term "Model-Based Systems Engineering" is a book by A. Wayne Wymore with the same name. [8] The MBSE term was also commonly used among the SysML Partners consortium during the formative years of their Systems Modeling Language (SysML) open source specification project during 2003-2005, so they could distinguish SysML from its parent language UML v2 ...
IBM Engineering Rhapsody (formerly Rational Rhapsody), a modeling environment based on UML, is a visual development environment for systems engineers and software developers creating real-time or embedded systems and software. Rhapsody uses graphical models to generate software applications in various languages including C, C++, Ada, Java and C#.
A challenge in the development of embedded and cyber-physical systems is the large differences in the design practice between the various engineering disciplines involved, such as software and mechanical engineering. Additionally, as of today there is no "language" in terms of design practice that is common to all the involved disciplines in CPS.
The value of each electrically emulated sensor is controlled by the plant simulation and is read by the embedded system under test (feedback). Likewise, the embedded system under test implements its control algorithms by outputting actuator control signals. Changes in the control signals result in changes to variable values in the plant simulation.
