OMDE consists of four integrated components: Dashboard, OMT Table Editor, FDD Viewers (1.3 / 2010 / 2025), and Diagram Editor, providing a unified and standards-aligned Object Model engineering platform. It Supports OMT 1.3, IEEE 1516-2010 (HLA Evolved), and evolving IEEE 1516-2025 (HLA 4) specifications. OMDE Supports multiple Object Models in parallel through independent OMDE instances. Each instance operates with its own dedicated toolbar and context-aware workflow.

1. Dashboard

The OMDE Dashboard provides a unified workspace for creating, importing, managing, and validating SimGe Object Models.

• Architectural complexity metrics

• Model health diagnostics (e.g., unused data types, inactive classes)

• Direct navigation from analytical insights to related editors

2. OMT Table Editor

The OMT Table Editor provides a modernized editing environment combining structured table views and dedicated dialog workflows.

• Consistent editing of Object Classes, Interaction Classes, Parameters, Dimensions, Directed Interactions, and Time Representations

• Integrated support for LogicalTime and LogicalTimeInterval definitions aligned with IEEE 1516-2025

• Modernized metadata tables including Tags, Transportations, Switches, Update Rates, Synchronization Settings, and Notes

• Improved validation and standards-aligned data handling

• Enhanced consistency and usability across all OMT elements

3. FDD Viewers (HLA 1.3, 1516-2010, 1516-2025)

OMDE provides integrated FDD/FED viewing and exchange capabilities across supported HLA standards.

• Import and export of HLA 1.3 FED files

• Import, export, and validation of IEEE 1516-2010 (HLA Evolved) FDD files

• Import, export, and validation of IEEE 1516-2025 (HLA 4) FDD files

• Improved cross-standard interoperability and processing consistency

The FDD Viewers include a fully modernized editing and inspection environment:

• Integrated Status Bar displaying real-time cursor position (Line/Column), selection details, and contextual information

• Inline Notification System providing action feedback (e.g., copy operations) without disrupting layout

• Quick Zoom Controls for immediate text scaling and improved readability

• Syntax Highlighting for FED, FDD, and generated code files, with structured color differentiation

• Line Numbering for precise navigation and collaboration

• Search Panel (Ctrl+F) with highlighted results for rapid content lookup

• One-Click Copy All capability for exporting full document content

These enhancements significantly improve readability, inspection efficiency, and usability when working with large or complex FED/FDD documents.

4. Diagram Editor

The Diagram Editor enables visual exploration of Object Models.

• Automatic generation of Object Class and Interaction Class diagrams

• Direct visualization derived from the underlying Object Model

• High-resolution PNG export for documentation, reporting, and design reviews

• Supports structural analysis and communication of model architecture

• FAME enables structured definition and management of Federation Architecture Models (FAM), supporting early-stage federation design, validation, and prototyping workflows.

• Federation execution properties — including federation execution name and related configuration parameters — can be defined and centrally managed within the architecture model.

• Federate applications can be added to or removed from the Federation Architecture Model, allowing flexible composition and refinement of federation structures.

• FAME provides a structured visualization of federation composition, supporting architecture analysis, configuration consistency, and design validation before runtime deployment.

• Code is separately generated for each federate application found in the federation architecture according to the federate's SOM.

• The structure of the generated code conforms to the layered architecture.

• The following pieces of code are generated:

  • The federate class that includes the skeleton code for federate ambassador callback event handlers for RACoN,

  • A class for each HLA class found in the simulation object model and supports the inherited classes,

  • The federate simulation object model (SOM) class,

  • The simulation manager class,

  • A static class (i.e. Tags) that consists of the user-supplied tags as static members.

• Each generated class is placed in a separate source file, improving modularity and maintainability.

• A code generation configuration dialog allows selection of HLA management services for which callback handlers will be generated.

• FED and FDD files are automatically exported to the generated source code directory according to the Federation Object Model (FOM).

• RG fully generates all HLA OMT 1516-2010 tables, including Interface Specification Services, producing comprehensive and standards-compliant documentation suitable for review and certification purposes.

The Project Explorer serves as the unified control center for managing every aspect of simulation development in SimGe.

• Object Models
  Inspect, navigate, and manage Federation Object Models (FOM/SOM) and their structural elements within a single hierarchical view.

• Federate Applications
  Configure, inspect, and validate all federate applications participating in the federation execution, directly in context.

• Generated Code & Artifacts
  Browse generated source code, project files, and related artifacts in a structured, searchable, and time-aware hierarchy.

By consolidating modeling, configuration, and generated outputs into one coherent explorer, SimGe provides a clearer mental model, faster navigation, and a workflow aligned with modern IDE expectations.

To ensure SimGe runs smoothly on your machine, please ensure the following prerequisites are met:

• Operating System: Windows 11 (64-bit recommended).

• Framework: Microsoft .NET 8.

• For Generated Code: Visual Studio 2026 or later is recommended to open and compile the simulation projects generated by SimGe.

• Code Generation Platform: RACoN v0.0.2.5 and upper
