In this paper a new approach f o r an overall system design is presented. It supports object-oriented system modeling f o r soflware components in embedded systems in addition to the well known time-discrete and time-continuous modeling concepts. Our approach supports structural and behavioral modeling with front-end tools and simulution/emulation with back-end tools. The XMI (XML Metudata Exchange) metamodel is used f o r storing CASE data to a commercial object repository and exchanging CASE datu. The CASE tool chain, presented in this paper, supports concurrent engineering with versioning and configuration management. Finally we discuss the suitability of XMI f o r concurrent engineering using the Unified Modeling Language notation for an overall system design cycle.
In this paper a new high-level system design approach for electronic systems is presented. It supports object-oriented system modeling of software intensive components with the Unified Modeling Language and time-discrete and time-continuous modeling concepts. Our approach supports structural and behavioral modeling with front-end tools and simulation/emulation with back-end tools. The XMI (XML Metadata Exchange) format and the UML metamodel is used for an exchange and storage of CASE data. The CASE tool chain, which we present in this paper, supports concurrent engineering with versioning and configuration management and provides tool adaptors for MATLAB/Simulink and ARTiSAN Real-Time Studio. Using the Unified Modeling Language notation for an overall system design cycle, the focus of this paper lies on the subsystem coupling of different modeling domains and a new code generation approach.
In this paper a methodology for architecture oriented Rapid Prototyping is presented. In the ver3, early development phases concept-oriented Rapid Prototyping is used to clarifi the requirements between the customer and the contractor. In the second, more complex phase of Rapid Prototyping, the architecture of the target system is used. So this kind of Rapid Prototyping is called "architectureoriented Rapid Prototyping ".
Most Electronic Control Units (ECU) use niicrocontrollerswith plenty of on-chip peripherals, sometimes applicationspecific microcontrollers with non-standard peripherals are used. But then, all these peripheral components must be present in the Rapid Prototyping system. To obtain this we developed an interface module with a FPGA f o r the peripheral parts of microcontroller based designs as well as a prototyping ECU which can be programmed with CASE-tools.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
