The uses of both the Unified Modelling Language and Rate Monotonic Analysis are increasing in the development of real-time systems. While both are addressing their usage it remains to be seen a clear, defined link between both UML and RMA. We present here a profile based upon the OMG’s UML Real-Time Profile (Schedulability Analysis Subsection) that allows the placement of timing information and the...
Important trends are emerging for the design of embedded systems: a) the use of highly programmable platforms, and b) the use of the Unified Modeling Language (UML) for embedded software development. We believe that the time has come to combine these two concepts into a unified embedded system development methodology. Although each concept is powerful in its own right, their combination magnifies...
This paper describes aspects of the process and methodologies used in the development of a complex system-on-chip. The open-standard modelling language SystemC played a key role in supporting the technical work, from early architectural modelling, through a defined refinement process to detailed cycle-accurate modelling elements, which enabled early co-simulation and validation work. In addition to...
The design of complex real-time distributed hardware/software systems commonly involves evaluating the performance of several design alternatives. Early in the design process, it is therefore desirable that design methods support constructing abstract models for the purpose of analysis. Recent extensions to the Unified Modeling Language (UML) that enable specifying schedulability, performance and...
Telecom equipment is composed of hardware and software components. Additionally, the test related software on the module, board and system level becomes a bigger relative part of the entire software content. This part gains importance as verification and integration complexity stays increasing at a high rate. This paper describes the characteristics of the embedded SW and more particularly of the...
