Syside

Pro Suite

Comprehensive SysML v2 tool suite composed of Modeler and Automator

Modeler

Fast, feature-rich SysML v2 modeling environment with textual editing, interactive visualization, tabular views, and a headless CLI for pipelines.

Key Features

Fulll SysML V2 textual editing features
Real-time syntax and semantic validation with SysML v2 standard rule diagnostics
Automatic diagram generation — element diagrams, view diagrams, sequence, use case, and block diagrams in color
Table views and matrix views — spreadsheet-style model inspection with editable cells that write back to the model
Views explorer — one-click access to all view definitions in the project
Headless CLI — validate, format, and export diagrams and CSV views from the command line
Runs on Windows, macOS, and Linux

Applications

Use Syside Modeler to author SysML v2 models in textual notation, visualize any element or view as an interactive diagram, inspect and edit your model in spreadsheet-style table and matrix views, synchronize requirements with your RM tool via ReqIF, and automate validation and diagram export in CI/CD pipelines using the headless CLI.

Automator

Python API for programmatic SysML v2 model access, editing, evaluation, validation, and report generation — built for automation and CI/CD pipelines.

Key Features

Programmatic model editing — create, update, delete, and move elements between namespaces
Report generation — extract model data and generate documents, tables, and reports using any Python reporting library
CI/CD integration — run validation, apply formatting, and export diagrams headlessly in any pipeline
ReqIF import and export — connect to Codebeamer, IBM DOORS, Polarion, and other requirements tools
Model evaluation — evaluate expressions, attributes, constraints, and SI unit quantities
Requirement evaluation — validate that assumptions implies requirements holds across your design

Applications

Use Syside Automator to query and edit models programmatically, evaluate design constraints and requirement satisfaction, enforce modeling standards as code in CI/CD pipelines, generate traceability reports at release time, and build custom integrations with PLM systems, requirements tools, and data pipelines.

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 Python interfaces and SysML v2 APIs. 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 Automator Python interfaces. Generate software artifacts, configuration files, simulation code, and test cases directly from your system models.
