Digital Engineering Validation Tool

Our free system model validation tool guides modeling consistency to reduce errors, aid analyses, and improve quality.


SAIC provides the Digital Engineering Validation Tool to the worldwide systems modeling and engineering community.

Intended for system modelers, engineers, and users, this tool improves the quality and functionality of your system models using state-of-the-art validation techniques we developed. We hope that community use of this validation tool will stimulate adoption and discussion of industry best practices.


What is it? Our tool is a set of validation rules and customizations. Intended to guide model development where multiple options are available, the tool ensures that a team of modelers always makes the same choice, creating model consistency. SAIC continues to mature its popular Digital Engineering Validation Tool, which consists of:

  • SAIC DE Profile (validation rules and customizations)
    • Validation Rules (both language and style) for Dassault Systemes/No Magic's MagicDraw and Cameo Enterprise Architecture
    • Customizations (including methods to connect deeply-nested ports, manage classification and data rights, and conduct failure analysis)
  • Model-Based Style Guide
  • Example System Model (based upon the Ranger lunar probe)
  • Explanatory Videos

What is the benefit? Use of validation rules in our tool should have an immediate and measurable impact on model quality. Style guides and language semantics are automatically enforced. This enables reviews of system content using analysis tools rather than human reviews, reducing review time from weeks to minutes for large system models. Also, the customizations we have provided allow synchronization between the parts that make a system architecture (structure) and the functions they perform (behavior).


NEW Version 1.9. v1.9 of SAIC's Digital Engineering Validation Tool adds model federation rules and a video tutorial for the included model template.

This release includes:

  • 201 Validation Rules (both language and style) for MagicDraw and Cameo Enterprise Architecture
  • A Rhapsody version of the Ranger example model
  • Video documentation for cloning the included model template, a demonstration of the Rhapsody Ranger model and using context patterns in Rhapsody

The SAIC validation rules were recently featured in a presentation at the 2022 American Institute of Aeronautics and Astronautics SciTech Forum. "A Mars Octet: Lessons Learned from Federating Eight Student Models in a SysML Class" illustrates how our validation rules support the creation of a coherent system-of-systems model by distributed teams. The paper, presentation and example models are available at the following links:
