Modern simulation systems are complex. They often combine real-time physics models, hardware interfaces, high-speed data logging, and deterministic control loops. Building and managing that environment from scratch is difficult and error-prone.

SIMulation Workbench (SimWB) offers a unified solution. It is a simulation framework that helps engineers build, test, and execute models with deterministic timing. Whether you are simulating a flight controller, validating an automotive subsystem, or developing control logic for industrial machinery, SimWB provides the tools to make your models run with real-world fidelity.

at the Core

SimWB is more than a modeling tool. It is a full runtime environment that manages the execution of simulation models alongside real-time I/O and scheduling. Built on top of RedHawk Linux, it ensures predictable execution with microsecond-level timing precision.

Developers can load models created in environments like MATLAB/Simulink, C/C++, or Python. These models are then compiled and executed within the SimWB framework, which handles:

• Scheduling model steps in precise cycles
• Synchronizing data between model and hardware
• Managing real-time threads and I/O latency
• Logging simulation data without disrupting execution

SimWB supports both Software-in-the-Loop (SiL) and Hardware-in-the-Loop (HiL) configurations, making it ideal for iterative development, integration testing, and full system validation.

GUI and Web-Based Control

SimWB includes a graphical interface that lets users manage simulations without needing to write scripts or edit configuration files. From the control panel, users can:

• Load models and configure inputs and outputs
• Start, stop, or pause simulation cycles
• View live variable values
• Set breakpoints or override inputs
• Launch post-processing tools

Flexible I/O Integration

Simulations often need to connect with the outside world. SimWB supports a wide range of hardware interfaces, including:

• Analog and digital I/O
• CAN, ARINC, and MIL-STD-1553 buses
• Serial and Ethernet devices
• FPGA-based expansion cards
• Custom drivers via open APIs

Designed for Scalability

SimWB is designed to grow with your project. Whether you’re running a single simulation on a desktop system or managing a network of synchronized nodes in a large-scale testbed, SimWB can scale accordingly.

It supports distributed execution, allowing components of a simulation to run on separate machines while remaining tightly synchronized. This is especially helpful in scenarios where I/O, compute, and model logic need to be separated for performance or architecture reasons.

Common Use Cases

• SIMulation Workbench is used across industries that require real-time modeling, such as:
• Aerospace: Flight control system simulation, pilot training environments
• Defense: Weapon system simulation and sensor integration
• Energy: Grid simulation and fault injection testing
• Robotics: Real-time kinematic and path planning validation

Engineers rely on SimWB to run test scenarios with hardware in the loop, validate safety-critical logic, and ensure that simulated environments behave as close to reality as possible.
