SimGe

Simulation Generator (SimGe) is a model-driven engineering environment for HLA-based distributed simulation, integrating object model engineering, federation architecture modeling, federate code generation, and structural, topological, semantic, and kinetic analysis. It connects the design of simulation information models and federation architectures with software generation and the examination of measured execution behavior. SimGe fully supports evolving IEEE 1516 standards, including comprehensive alignment with IEEE 1516-2025 (HLA 4), while maintaining backward compatibility with earlier HLA specifications. 

SimGe includes an integrated Object Model Development Environment (OMDE), Federation Architecture Modeling Environment (FAME), report generator, code generator, and a Telemetry Inspector Visualizer, providing an end-to-end toolchain for HLA-based simulation engineering from object modeling and federation architecture design through code generation to post-run telemetry analysis.

The Object Model Development Environment (OMDE) supports the creation, inspection, validation, and evolution of Federation Object Models (FOMs) and Simulation Object Models (SOMs). Integrated OMT tables, class diagrams, document viewers, dependency management, and analysis dashboards provide complementary views of model content and organization. Supported import, editing, validation, and export workflows cover HLA 1.3, IEEE 1516-2010 (HLA Evolved), and IEEE 1516-2025 (HLA 4), including FED and FDD artifacts.

The Federation Architecture Modeling Environment (FAME) brings federate applications, FOM/SOM associations, module dependencies, RTI connections, instance multiplicities, and host assignments into a unified architectural model. Federation Structure Diagrams and UML deployment views expose federation composition and deployment topology, while readiness checks and module-composition diagnostics support early design review and federation prototyping.

The Code Generator translates federation architecture and associated SOMs into C#/.NET federate integration code for Fora client,, targeting HLA 4. Generated components include federate and lifecycle scaffolds, object and interaction representations, model bindings, datatypes, and codecs. A layered architecture provides extension points for application behavior, while optional telemetry instrumentation preserves model context for subsequent runtime analysis (Topcu 2013 and Topcu 2011).

SimGe provides complementary analysis perspectives:

• Static structural and topological analysis characterizes model size, inheritance depth and breadth, hierarchy load, structural imbalance, and polymorphic potential across object and interaction domains.

• Semantic analysis examines datatype-derived payload weights, semantic saturation, payload dispersion, and the balance between object and interaction domains, helping identify concentrated model burdens and compare alternative designs.

• Kinetic analysis connects design-time model characteristics with runtime activity and measured costs. Telemetry-based workflows examine sender work, delivery fan-out, state exposure, serialization performance, selectivity, and operational drift under recorded workloads.
