Augmenting requirements with models to improve the articulation between system engineering levels and optimize V&V practices

Model-based systems engineering has developed significantly over the last few years, resulting in an increased usage of models in systems specification and architecture description. The question of the positioning of requirement engineering versus MBSE is a recurrent one.

This talk describes one vision of this articulation where textual and model requirements actually complete each other. The results are improved contracts across engineering levels and more formalized V&V practices.

Feedback on deployment of Capella at Framatome

Open source software like Capella comes with advantages like the easy way to extend or customize it and drawbacks including support to users especially when they are working in a collaborative way. This presentation will share how Capella has been deployed in Framatome so that systems engineer/architect do not care much about technical issues but remain focus on their business.

Furthermore, in a context where many companies have their data described in excel files, XLS Pivot (part our MBSE Suite tool), is a generic MBSE solution developed by Framatome on top of Capella to help users to exchange data from Excel to Capella and vice versa. This presentation will show XLS Pivot in action.

Capella integration with Teamcenter

The main reason we do product architecture is to communicate to downstream product development what they need to build, thus the need to integrate the Capella product architecture with the product lifecycle through PLM (Product Lifecycle Management). Siemens’ Teamcenter PLM is used by millions of developers around the world in thousands of organizations. Capella is being integrated with Teamcenter enabling it to actively participate in the product lifecycle to drive the entire product development process.

This session will provide an update on Siemens’ PLM integration progress and demonstrate the value of a Capella enabled product lifecycle.



Christoph Marhold, Siemens PLM Software


Model Execution and System Simulation in Capella

A common need in system architecture design is to verify that if the architect is correct and can satisfy its requirements. Execution of system architect model means to interact with state machines to test system’s control logic. It can verify if the logical sequences of functions and interfaces in different scenarios are desired.

However, only sequence itself is not enough to verify its consequence or output. So we need each function to do what it is supposed to do during model execution to verify its output, and that is what we called “system simulation”.

This presentation introduces how we do model execution in Capella, and how to embed digital mockup inside functions to do “system simulation” with a higher confidence.

Integrating Capella with your own ecosystem of tools

The current industrial trends related, among others, to digital twins or large scale systems of systems, drive companies to using MBSE tools such as Capella. However, these tools have to be part of the overall ecosystem of tools used by such companies (e.g. complex systems manufacturers).

One example is the integration with a PLM solution, that we will illustrate by explaining how we have integrated Capella and Teamcenter by developping System Modeling Workbench.

Beyond technical aspects (build the product, managing its lifecycle with regards to constraints brought by the market and by the open source processes, etc.) we will also discuss the organization of the collaboration needed to perform this kind of integration project.

Providing early timing analysis of the system design

When designing real-time systems, one issue is to grant that the system will always behave properly within the expected time constraints.
By capturing the design choices in Capella (periodic/sporadic events, precedence relation between tasks, network communication between resources, mutual exclusion resources, etc.), Tideal viewpoint not only allows to compute the worst-case execution time for end-to-end flows traversing the system but also provides some feedback to the architect to better understand the temporal behavior of the system.

Model-based safety analysis on Capella using Component Fault Trees (CFTs)

The importance of mission or safety-critical software systems in many application domains of embedded systems is continuously growing, and so is the effort and complexity for reliability and safety analysis. Model-based system engineering (MBSE) is currently one of the key approaches to cope with increasing system complexity.

With Component Fault Trees (CFTs) there is a model- and component-based methodology for safety analysis, which extends the advantages of model-based development to safety & reliability engineering. In this talk, we demonstrate how to ease the development of safety-critical systems in industrial practice by extending MBSE in Capella with model-based safety analysis using Component Fault Tree methodology.

An Excel-based Systems-Engineering Tool for Knowledge Sharing and Collaboration across the Enterprise

MapleMBSE is an Excel-based tool that makes it easy for every stakeholder to engage with the Systems Engineering project without requiring them to be an expert in your primary SE tools.
MapleMBSE makes broad engagement possible with Excel-based, task-specific interfaces for each activity in the systems design process.
By giving all stakeholders access to the process through a live, two-way connection to systems model, you can ensure that all stakeholders can collaborate through the “single source of truth”, allowing them to work faster, avoid errors, and reduce unbudgeted costs.
This presentation will demonstrate how MapleMBSE can be used for several use-cases on the Capella platform, based on Maplesoft’s experience with NASA JPL in the US and Nissan in Japan.

MBSE & PLE: Systematic Reuse of Capella Models with pure::variants

In domains that deal with the development of complex systems consisting of software and hardware it is often a challenge to find an efficient and holistic reuse strategy for existing engineering assets that allows to keep the engineering competitiveness high even though a growing number of markets and specific customer needs shall be covered by a product family.
Product Line Engineering (PLE) is a well-known approach to address this challenge. In this session we will cover how PLE and MBSE can be brought together using the open-source MBSE solution Capella in combination with the Variant Management tool pure::variants to implement a systematic reuse of system architecture across multiple product variants.
