At the embedded world 2020, LieberLieber Software will present the latest release of LemonTree as well as the codeBeamer ALM – Enterprise Architect Integration 2.0, developed in cooperation with Intland Software.

Vienna/Nuremberg, February 19, 2020, embedded world – The webinar on codeBeamer ALM – Enterprise Architect Integration 2.0, held on February 11 with over 100 participants, shows the great interest in this new solution, which will also be presented at embedded world 2020. The integration enables users to synchronize requirements, model attributes, links and references between codeBeamer ALM and Enterprise Architect. This makes it even easier to navigate back and forth between the two platforms, while development data is automatically synchronized. Daniel Siegl, CEO of LieberLieber Software: “GIT Style Workflows and integrations are currently central topics in the MBSE community! When it comes to Application Lifecycle Management, we think codeBeamer is the best solution for these processes. Therefore, it was clear for us to deepen our cooperation with Intland to develop additional functionality for the integration of ALM and MBSE. At our booth at embedded world we will be happy to tell you more about how you can best use the new integration for your projects!”

Petwalk, the Austrian specialist for automatic dog and cat doors, is on an expansion course. In order to meet the strict safety regulations required for access to the American market, the company sought the support of LieberLieber. Together, they are now developing a model-based solution that demonstrably meets all safety regulations.

Wien/Ternitz – Petwalk Solutions, founded in 2010 as a result of a research project in Ternitz, Lower Austria, specializes in next-generation automatic doors for cats and dogs. And, since pet owners care a great deal about the well-being of their four-legged friends, safety-critical aspects play a major role in Petwalk’s door development process for which proven standards from the automotive industry are being used as criteria for development and testing. Klaus Kindl, founder and managing director: “Our doors are subject to demanding security requirements similar to those that apply, for example, to passenger elevators. We must comply with requirements for both the electronic and mechanical components. We are very export-oriented and already deliver to more than 30 countries worldwide; however, in order to be able to export to more complex legal markets such as the USA, we had to start a re-engineering project.” The need for a model-based approach soon became apparent, which naturally led to contact with LieberLieber. Daniel Siegl, Managing Director of LieberLieber: “Following my presentation at the Austrian Software Industry Association (VÖSI), the project’s objectives soon crystallized during our conversation. Petwalk’s use case makes it particularly important to formally demonstrate compliance with the legal requirements on its software. Model-based development is ideal for this.”

Models document the fulfilment of legal requirements
One big advantage of model-based software and systems development is the fact that compliance with legal requirements can be proven automatically in the model. Since traceability is nowadays mandatory in more and more industries and countries, the use of models is likewise growing in prevalence. Markus Hammer is Managing Director of CertaBit Engineering and fills the role of CTO at Petwalk: “As I have worked with Enterprise Architect in the automotive sector before, I was familiar with the strengths and challenges of this modeling platform. Looking for enhancements I came across LieberLieber’s LemonTree and Embedded Engineer, two powerful solutions that extend the capabilities of Enterprise Architect.” After initial tests and training, Hammer was quickly convinced of the quality of the LieberLieber extensions. “Embedded Engineer allows us to debug directly in the model. We were able to bring the firmware of our hardware suppliers in-house and we now get much faster, error-free and clearly structured code.” Over the course of development the team was confronted with the challenge of versioning and how development cooperation should work. “The ability to block other users had not been implemented into Petwalk’s workflow as we would have liked. LemonTree provides us with an optimal solution that supports us in all versioning issues that occur in a team environment,” explains Hammer. Ultimately, the simultaneous use of Embedded Engineer and LemonTree provides excellent conditions for upcoming development challenges.

Now, connecting the old and the new is no problem.
Because the Petwalk door’s electronics run on embedded Linux and Windows Embedded, the development team decided to clearly separate old and new functions and connect them via an interface. In this way, existing functions can be easily retained while the new ones can be created right away in the modeling tool. LieberLieber’s approach is very pragmatic: You can continue to use existing software and still switch to a model-based approach when it makes sense. This makes it much easier for us to decide on the fly whether or not to take this step. This also allow us to intensify our cooperation with LieberLieber on an ongoing basis, trying out new things over and over again,” says Kindl. Petwalk intends to kick off the year 2018 with a splash in the US market: The first prototypes from the re-engineering project are to be presented in January at the Consumer Electronics Show (CES) in Las Vegas.

Development of a solution for optimizing and debugging embedded software at the model level

Vienna/Höhenkirchen-Siegertsbrunn, …… – LieberLieber Software and Lauterbach have joined forces to create a solution for the optimization and debugging of embedded software directly on the model in addition to the source code level. “This cooperation with Lauterbach, the world market leader for hardware-assisted debuggers, further complements our offering in the area of embedded systems development. In response to continually growing demand, this joint solution now enables debugging directly in the UML model itself and thereby more efficient and less time-consuming troubleshooting,” says Daniel Siegl, CEO at LieberLieber Software.

This solution was presented by both companies at the Embedded World Conference, Feb. 24^th till 26^th, 2015 in Nuremberg, Germany, as a specially-created demo version.

Growing demand now met by an optimized solution
“All of our debugging solutions allow the search for errors down to the source-code level in all popular object-oriented languages. To facilitate debugging in UML-generated source code, we looked for a partner that allows users to debug directly at the model level. With LieberLieber we have found the right company that can refer to extensive experience in solving this challenge. Although the embedded market in terms of model-based debugging is still a bit hesitant, we expect great demand both in Germany and in the US for this compelling solution,” explains Rudi Diensteck of Lauterbach, stressing the importance of the cooperation.

The new solution combines the Lauterbach TRACE32® In-Circuit Debugger product line with the LieberLieber UML Debugger. The TRACE32® has already shipped to 100,000 customers, and supports all common CPU architectures including ARM/Cortex, Intel x86/x64, Power Architecture and many others. The UML Debugger is part of LieberLieber Embedded Engineer for Enterprise Architect, a solution for the model-based development of embedded systems. The graphical debugger is integrated into the Enterprise Architect UML platform by Sparx Systems, used by over 350,000 users worldwide. It allows you to set hardware breakpoints directly in the model and then go through the process step-by-step. The time response of the system being analyzed is not impaired, which is decisive for the debugging of embedded solutions.

“This jointly-created solution allows customers to graphically and efficiently analyze the system for errors, and optimize simultaneously. It gives UML developers the power to ensure that the critical factors of the embedded system are not changed,” says Dienstbeck.

LieberLieber strengthens its partnership with Willert Software Tools to develop a real-time solution for UML code generation

Vienna/Bückeburg, November 27th, 2014 – The cooperation that started in 2011 between the two embedded engineering specialists LieberLieber Software and Willert Software Tools has resulted in an optimized UML-based solution, presented at the Embedded Software Engineering Congress 2014. In view of continually growing requirements, especially in the area of embedded software development, this new solution can help developers to create more complex real-time-critical systems while adhering to appropriate standards. “Built on years of cooperation with Willert, we now offer an efficient Plug&Play solution that will introduce a previously unknown scope of simplicity and speed into new projects. We are also deliberately addressing  developers who have not yet been able to gain very much experience in UML and have not taken the step into model-based engineering,“ explains Daniel Siegl, CEO of LieberLieber Software.

This jointly-developed solution package combines “LieberLieber Embedded Engineer” with Willert’s “Embedded UML Framework RXF.” The combination of these two products, based on Enterprise Architect by Sparx Systems, has resulted in a very efficient development environment for model-based development for embedded systems.

Attractive price, high efficiency
For Walter van der Heiden, CTO at Willert, this new solution is also attractive due to its outstanding cost/performance ratio: “We can now offer the market an efficient tool for less than 1,000 euros. At the same time, we were able to reduce the number of implemented solutions while greatly increasing efficiency. That is how users of this new tool can save a lot of time and does not have write any code!“ The Willert Framework serves as the link between the UML and hardware, which also optimizes the configurability and demand for resources. In come cases, the size of the code could be reduced by almost 60% to only a few kB.

Following exhaustive tests, the renowned construction industry supplier Hilti decided on LieberLieber’s Code Generator for Embedded Systems for Enterprise Architect.

(Vienna/Kaufering bei München, 10.04.2014) Following exhaustive tests, the renowned construction industry supplier Hilti decided on LieberLieber’s uml2code Code Generator for Embedded Systems 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 parter 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 uml2code 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 the Code Generator 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.
