Requirements specification and architecture design for internet-based control

The Internet is playing an important role not only in information retrieving, but also in industrial processes manipulation. This paper describes an approach to writing requirements specification for Internet-based control systems and to deriving architecture for this new type of control systems according to the requirements specification. Specification is described in terms of a functional model and then extended into information architecture. Distinct from the functional model, the information architecture gives an indication to the architecture of the Internet-based control systems. An integrated-distributed architecture has been derived from the functional model and the information architecture as a case study

Generating VHDL Source Code from UML Models of Embedded Systems

Selected from 7th IFIP TC 10 Working Conference, DIPES 2010, and 3rd IFIP TC 10 International Conference, BICC 2010, Held as Part of WCC 2010, Brisbane, Australia, September 20-23, 2010, ProceedingsInternational audienceEmbedded systems' complexity and amount of distinct functionalities have increased over the last years. To cope with such issues, the projects' abstraction level is being continuously raised, and, in addition, new design techniques have also been used to shorten design time. In this context, Model-Driven Engineering approaches that use UML models are interesting options to design embedded systems, aiming at code generation of software and hardware components. Source code generation from UML is already supported by several commercial tools for software. However, there are only few tools addressing generation code using hardware description languages, such as VHDL. This work proposes an approach to generate automatically VHDL source code from UML specifications. This approach is supported by the GenERTiCA tool, which has been extended to support VHDL code generation. To validate this work, a use case focused in maintenance systems attended by embedded systems is presented
