Systems Modeling Language
The Systems Modelling Language (SysML) is a general purpose modeling language for the definition and design of embedded systems containing electronics, software and networks in a graphical manner. VisualSim enables systems engineers to take a SysML and simulate with traffic, mapping application to the architecture and use-cases, to determine the performance, power consumption, scheduling and functionality.
SysML provides graphical representations based on a semantic foundation for modeling system behavior, requirements, structure, and parametrical elements which are used to integrate with other engineering analysis models using the OML XML Metadata Interchange (XMI®).SysML is defined as an extension of a subset of the Unified Modeling Language (UML).
SysML uses the concept of the ‘block’ as the basic unit structure to represent hardware, software, information, personnel, procedures, and facilities. Block definition diagrams and internal block diagrams are used to represent a system structure as illustrated below:
The SysMLBehaviour Diagram includes:
- SysML Use Case Diagram – high level description of functionality delivered through interactions between parts of the system
- SysML Activity Diagram – Illustrates the flow of data and control between activities
- SysML Sequence Diagram – interactions between collaboration parts of the system
- SysML State Machine Diagram – identifies transitions occurring in response to events in the system
SysML is a trademark of the Object Management Group.
Model-based systems engineering (MBSE) is a systems engineering methodology that focuses on creating and exploiting domain models as the primary means of information exchange between engineers, rather than on document-based information exchange.Systems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems. A common type of systems modeling is function modeling. VisualSim extends systems modeling with performance and power model, by providing an underlying discrete-event simulator.
The Unified Profile for DoDAF/MODAF (UPDM) is the product of an Object Management Group (OMG) initiative to develop a modeling standard that supports both the USA Department of Defense Architecture Framework (DoDAF) and the UK Ministry of Defence Architecture Framework (MODAF).
Our modeling and simulation platform ensure that the specification has been fully tested and optimized, so that there are no surprises during system integration. The Architect simulates the use-cases on a target architecture platform and conducts trade-offs studies to optimize the specification. Models simulated in VisualSim generate reports on performance, power and functionality to identify system bottlenecks, and ensure there is no over-or under-design.
