Reduce development risk before physical systems exist — validate control logic, fault handling and edge cases entirely in simulation.
Hardware-in-the-Loop (HIL) simulation runs your actual ECU, VCU, BMS, PLC or motor controller against a real-time simulated model of the physical system it will control, instead of the real hardware. The controller “sees” realistic sensor and actuator signals generated by the simulation and responds exactly as it would in the field — so integration and fault-handling issues surface while the software is still in development, not after a physical prototype has already been built.
TMCS builds these environments on NI VeriStand, PXI, LabVIEW and TestStand, giving engineering teams a validated, closed-loop test platform that runs the real control logic continuously against a real-time plant model — catching problems weeks or months earlier than physical testing alone would allow.
TMCS is a leading engineering solutions company specializing in automated testing, simulation, validation, and NI-based engineering platforms. As an NI Certified System Integrator, we help organizations across Automotive, Electric Vehicles, Aerospace, Defence, Industrial Automation, and Energy sectors validate complex embedded systems with confidence.
TMCS delivers HIL validation as a five-stage engineering process, from requirement to regression-ready test suite.
Functional and fault-response requirements mapped against the product specification
Vehicle, motor, actuator and plant behaviour simulated in real time on NI VeriStand
Controller connected via CAN, CAN FD, LIN and Ethernet exactly as it would be to the real plant
Fault scenarios programmed and automated closed-loop sequences run in LabVIEW/TestStand
Results captured, trended across builds, and re-run automatically as control software evolves
Modern vehicles, aircraft, industrial machines, and energy systems depend on increasingly complex software and embedded controllers. Traditional validation methods often rely heavily on physical prototypes, making testing expensive, slow, and difficult to scale.
| Aspect | Physical Prototype Testing Only | HIL Simulation |
|---|---|---|
| Testing Stage | Testing begins after a physical prototype is available | Testing can begin early, before the complete physical prototype is built |
| Hardware Dependency | Requires physical hardware and prototypes for testing | Uses real controllers with simulated plant and system behaviour |
| Test Coverage | Limited by hardware availability and physical test conditions | Enables repeatable testing across a wide range of operating conditions |
| Fault Testing | Some faults can be difficult, costly, or unsafe to reproduce physically | Fault conditions can be simulated safely and repeatedly |
| Testing Speed | Testing cycles can be slow due to hardware setup and configuration | Automated scenarios can be executed rapidly and repeatedly |
| Cost | Requires multiple prototypes, test setups, and physical equipment | Reduces dependence on repeated physical prototypes and test setups |
| Repeatability | Results can vary due to physical conditions and manual setup | Identical test scenarios can be reproduced consistently |
| Development Cycle | Issues may be discovered later during physical testing | Issues can be identified earlier, accelerating development and validation |
