SimGe

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 advanced visual exploration and analysis of Object Models through a fully redesigned infrastructure.

• Automatic generation of Object Class and Interaction Class diagrams

• Directed Interactions Diagram for explicit visualization of interaction flows between classes 

• 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. With the 0.4.4 update, it now supports professional UML Deployment Diagrams to model physical topology, including RTI infrastructure nodes, network buses, and nested execution environments.

• Federation execution properties — including execution names, configuration parameters, and modular FOM/SOM associations — are centrally managed within the model. New quick-navigation "Jump to OMT" buttons and a dedicated MOM Explorer for IEEE 1516-2025 system modules ensure seamless transitions between architecture design and object modeling.

• Federate applications can be added to or removed from the model, featuring visual multiplicity indicators (stacked boxes) and real-time architectural health badges. These diagnostic badges provide instant visual feedback on naming conflicts, missing modules, or configuration gaps directly on the diagram.

• FAME provides a multi-dimensional visualization of federation composition through interactive Federation Structure Diagrams (FSD).  Features like "pulsing" connection lines, rich metadata tooltips, and professional legends support deep architecture analysis and design validation before runtime deployment.

The Code Generator now fully targets the Fora.Client and produces clean, modern, HLA 4–compliant federate code aligned with the IEEE 1516-2025 HLA Federate Protocol. 

• Code is generated separately for each federate application defined in the federation architecture, based on its SOM.

• Generated structure conforms to a layered architecture, ensuring separation of concerns and maintainability.

• Async-ready Simulation Manager implements the full federation lifecycle (connect → create → join → initialize → resign → dispose).

• Clean federate scaffold generated as a partial class, without legacy RACoN inheritance.

Generated Components

• Federate class including skeleton callback handlers (Fora-compatible event handling model)

• One class per HLA object/interaction class, including full inheritance support

• Federate Simulation Object Model (SOM) class

• Simulation Manager class (lifecycle orchestration)

• Static Tags class with user-defined tags generated as ReadOnlySpan<byte> using UTF-8 literals ("..."u8)

Additional Capabilities

• Each generated class is placed in a separate source file for improved modularity.

• Code generation configuration dialog allows selection of HLA management services and callback coverage.

• FED and FDD files are automatically exported to the generated source directory, consistent with the 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
