Modeling context

› Modeling tools have been used at Ericsson since mid 90’s › Used for modeling different aspects

– System, software, implementation, platform, network, data

› Demonstrated benefits in many different contexts – Currently relying mainly on commercial proprietary tools, e.g. RSA,

RSA RTE, Rhapsody, BrigePoint, EA, PowerPoint

› But, they have also failed in other contexts – Modeling tools must be easier to use – Better DS(M)L support is required – Role of tools is to make designers more productive, not to add

complexity! – No real evolution over the last decade

Open source Modeling tools

› Need open source alternatives to existing modeling tools

› Not free! – Less mature than open source tools covering other software

development aspects, e.g. GNU, GCC, GDB since 1980 – Need to invest to contribute to the industrialization

› Key requirements for open source solution

– Allow developing customization and DS(M)L – Provide integrations with other required development tools – Allow protecting our core IP’s – Offer commercial support

Why System Modeling ?

Produce and communicate system product documentation in a more efficient way than the traditional text based method by using UML and tool support Reduce the complexity of handling large systems and to make the documentation consistent in all parts

WCDMA Unified Modeling (WUM)

WCDMA Unified Modeling (WUM) is a methodology for modeling at WCDMA RAN (WRAN) system level. It includes a meta-model that defines structuring and modeling principles, ways of working and tools

Drivers for WUM

› One source and Consistent system information

› Manage large systems › Raise level of abstraction › Make it easy to find information and

to navigate › Architectural focus › Enable automation to reduce manual

intervention › Support many users in an Agile

environment

› Open source solution will allow developing –Advanced support for DS(M)L –Model-based tracing & debugging –Development of new runtime(s)

› Support for distribution and multi/manycores –Model peer review with Git/Gerrit –Tool/model integration framework –Product Line Management (PLM) and variation points –Deployment analysis
