HILTI chooses Code Generator

Following exhaustive tests, the renowned construction industry supplier Hilti decided on LieberLieber’s Embedded Engineer for Embedded Systems for Enterprise Architect. Vienna/Kaufering next Munich – Following exhaustive tests, the renowned construction industry supplier Hilti decided on LieberLieber’s Embedded Engineer for Enterprise Architect. Roman Bretz, CTO of LieberLieber Software: “We are proud that we could convince the Hilti development team of the benefits of our Code Generator after a one-year pilot phase. This confirms that we can also generate UML models from complex code which suits the very high requirements of the embedded industry. Moreover, our approach allows already existing code to be integrated without a problem – which is decisive for entering running projects.” As a partner of Sparx Systems, LieberLieber creates solutions for the optimized, user-friendly implementation of the popular UML modeling tool Enterprise Architect, used by over 300,000 users world-wide. LieberLieber Embedded Engineer is especially aimed at embedded software developers and software architects in the area of Embedded Systems, but can also be useful for testers and integration managers. The solution enables code generation from UML structures, state machines and activity models, and creates platform-independent C++ and MISRA-conform C-Code from UML models. Big test, big benefits Hilti supplies the construction industry globally with technologically-leading products, systems and services, and employs around 21,000 associates in more than 120 countries. Software for electrical power tools is developed at the Kaufering development center. Dr.-Ing. Michael Fuchs, Software, Electronics & Drives Department, who lead the LieberLieber Codegenerator implementation project: “Due to its brilliant cost/performance ration, Enterprise Architect has been successfuly implemented at the Hilti headquarters in Liechtenstein, however without code generation. Therefore, in close collaboration with LieberLieber and with the assistance of a student trainee, we have begun to closely examine the code generator and adapt it to our specifications. The goal of this totally new approach has been to further improve the quality and productivity of our developments. Our project expectations have been surpassed and we have been able to clearly achieve all goals!” All guidelines met The topic of code generation has occupied Hilti developers for several years, therefore everyone is happy to finally have found a suitable solution in LieberLieber uml2Code. One of the key conditions for the selection of LieberLieber Embedded Engineer has been that it cannot presuppose any special requirements (such as a framework). Already-existing code should continue to be useable, and taken over into the entire solution problem-free. In addition, the Generator must also be open for company-specific adaptations. “When implementing other code generators, these requirements were not fulfilled. Therefore, it soon became clear that the approach of LieberLieber was very practical and promising for us,” highlights Fuchs. The student trainee implemented company-specific adaptations in close cooperation with LieberLieber. Such a project also naturally implies a certain learning curve: “Since during code generation activity diagrams and state machines play the greater roles, the internal learning curve can be reduced to one week. After this time, our developers can already model on their own and generate runnable code – another very positive surprise,” concludes Fuchs. As a next step, a suitable debugging solution is being developed with LieberLieber partner iSYSTEM to complete the code generation. Photo: Hilti Corporation
