Simulation Framework Development

At the heart of every great simulation lies a flexible, scalable framework, and DiSTI designs them from the ground up while incorporating COTS, GOTS, and FOS software when appropriate.

Our engineers build modular simulation architectures that connect models, data, and visualization engines seamlessly across your ecosystem.

Customizable System Design: Aligns with your specific requirements, from physics-based modeling to maintenance procedure execution.
Scalable Implementation: Supports single-platform trainers to enterprise-level, multi-domain simulation networks.
Extendable Architecture: Future-proofed design ensures your simulation framework evolves alongside new technologies and requirements.

From rapid prototyping to full-scale deployment, DiSTI’s frameworks are built to perform, reliably, repeatably, and across decades of program use.

MM, CIGI, DIS, ARINC 661, and HLA Integration

Simulation environments don’t exist in isolation, they depend on robust, standardized communication between systems.

DiSTI’s engineering team specializes in integrating and extending simulation interoperability protocols including:

MM (Message Manager): An open protocol created by DiSTI for communication between simulation components and Virtual Environments
CIGI (Common Image Generator Interface): Synchronize visual systems and control inputs for advanced image generation.
DIS (Distributed Interactive Simulation): Enable real-time, multi-node interaction across distributed networks.
HLA (High-Level Architecture): Ensure compatibility and federation management for large-scale, joint simulation environments.
ARINC 661: For creating Cockpit Display System and the communication to User Applications in avionics

Our engineers have integrated these standards across countless programs, from ground vehicles and cockpits to maintenance trainers and command-center environments. When interoperability matters, DiSTI is the team trusted to make complex systems communicate flawlessly.

Custom Toolchain and Middleware Engineering

Every organization’s development environment is unique, and so are the tools it depends on.

DiSTI engineers design and integrate custom toolchains and middleware layers that eliminate workflow friction and accelerate delivery.

Toolchain Customization: Integrate GL Studio, VE Studio, Unity, Unreal , and proprietary tools into cohesive workflows.
Middleware Engineering: Develop software bridges that unify simulation components, automate testing, or enhance runtime behavior.
Standards Alignment: Ensure compatibility with existing modeling, database, and control frameworks.

From automotive hardware-in-the-loop (HIL) systems to complex defense training ecosystems, DiSTI’s custom software engineering delivers seamless interoperability and streamlined performance.

UI/UX and Runtime Performance Optimization

Even the most advanced simulation system is only as good as its usability and responsiveness.

DiSTI’s engineering teams optimize both the user experience (UX) and runtime performance to ensure your systems are intuitive, efficient, and stable.

Human-Machine Interface Design: Create responsive, data-driven interfaces for real-time control and feedback.
Performance Optimization: Reduce load times, improve frame rates, and enhance stability across hardware targets.
Cross-Platform Consistency: Deliver identical performance and fidelity across desktop, embedded, and immersive environments.

Our engineering-driven approach ensures your systems not only work, they work better, faster, and longer.

The Company Behind the World’s Most Trusted Simulations

For over 30 years, DiSTI has operated quietly behind the scenes, powering some of the most recognizable simulation programs in the world.

From U.S. Army vehicle trainers to commercial aviation displays and automotive HMI systems, our software forms the digital backbone of mission-critical systems used every day.

Organizations choose DiSTI not because we’re the loudest name in simulation, but because we’re the most trusted partner when precision, reliability, and deep engineering expertise matter most.
