Most Popular use Cases for SysIDE Pro

Automatic asset generation from the model

Generate documentation, diagrams, and reports in various formats directly from your SysML v2 models with automated workflows. Keep all assets synchronized with your model through built-in Python interfaces.

Model simulation, analysis and validation

Execute and validate your system models starting from design phase. Detect issues early by running comprehensive model checks and simulating system behavior before implementation.

Integrating multiple engineering tools and workflows

Connect your existing SysML v2 engineering tools through SysIDE Pro Python interfaces and SysML v2 API. Seamlessly integrate with PLM systems, requirements management tools, and CAD software while maintaining model consistency.

Embedding DSLs into SysML v2 models

Create and integrate domain-specific languages within your SysML v2 models to utilise specialized engineering concepts. Extend the modeling capabilities with custom DSLs while maintaining compatibility with the core SysML v2 standard.

Collaborative model editing

Work simultaneously on models with your team through real-time collaborative editing and version control integration. Track changes, manage conflicts, and maintain model consistency across your entire engineering team.

Automatic code generation

Transform your SysML v2 models into implementation code with template engines working through SysIDE Pro Python interfaces. Generate software artifacts, configuration files, simulation code, and test cases directly from your system models.

Testimonials

What our users are saying

Tim Weilkiens

CEO of OOSE, co-Chair SysML v2.0 FTF, MBSE Podcast host

“With SysIDE it is a great experience to do textual SysML v2 modelling in a convenient development environment.  I love this new style of SysML modelling!”

Jasper Bussemaker

Researcher at DLR

“SysIDE CE allows us to rapidly learn and understand SysML v2, to assess how we can use it to develop innovative aerospace systems in the future. The editing experience is already great, and I’m looking forward to what future versions will bring!”

Frequently Asked Questions

What our users are asking

At current release, yes. SysIDE CE is a VS Code extension and is used for editing the model. SysIDE Pro is a Python package (for now) used for programmatic model manipulation in Python scripts. Both complements each other.

Yes, it can. This is especially useful for users that do not use VS Code, or for users that want to use SysIDE Pro in a non-GUI way, e.g. in automated pipelines.

Yes, SysML v2 is based on KerML, and therefore SysIDE Pro needs to support KerML models as well.

No, both SysIDE CE and SysIDE Pro only supports SysML v2.

No, SysIDE Pro currently only supports Python 3.12, with 3.13 coming soon. Currently, there are no specific plans to support older versions of Python.

SysIDE Pro has no telemetry tracking algorithms embedded in it, thus it does not collect any usage data.

No, running SysIDE Pro after installation does not require internet connection.

Yes, SysIDE Pro can be used in Docker containers. This is particularly useful for cloud environments or when you cannot meet the minimum requirements locally. You’ll need to use Python 3.12 as the base image and follow the instructions for Ubuntu in the Install SysIDE guide.

SysIDE Pro is platform-independent and runs on Windows x86, macOS Apple Silicon, and Linux x86 operating systems. For other operating systems, you can use Docker as shown in the previous question.

Yes, SysIDE Pro is designed to work well in automated environments and CI/CD pipelines. Its command-line interface makes it suitable for automation scenarios.

Yes, SysIDE Pro works with standard version control systems like Git, allowing teams to collaborate on SysML v2 models effectively.
