Hardware-in-the-loop (HIL) simulation is a technique that is used in the development and test of complex real-time embedded systems. Hardware-in-the-Loop (HIL) testing systems comprise an essential contribution to quality assurance during the early phases of Electronic Control Unit (ECU) development. By simulating the model components, the simulator facilitates the development and testing of the functions and diagnostic behavior of ECUs in the safety of a laboratory. As the system is simulated, the developer and testers are able to push the system to its boundaries, which adds significantly to the reliability of the software, reduces the test execution, and increases the test coverage.
The complexity of the plant under control is included in test and development by adding a mathematical representation of all related dynamic systems. These mathematical representations are referred to as the plant simulation. The embedded system to be tested interacts with this plant simulation.
HIL simulation provides an effective platform by adding the complexity of the plant and simulation of the system to the test code running on the actual production hardware.
Methodica Technologies has expert HIL consultants who can help you with:
(1) Setting up HIL test benches for new or existing projects.
(2) Developing and fabricating a harness for connecting the controller to the HIL system.
(3) Developing open and close-loop models in Matlab & Simulink to simulate the system and test the production controller.
(4) Developing complete HIL databases for different HIL platforms, such as:
(a) dSPACE (Mid-Size, full size & Scalexio).
(b) ETAS (PT-LABCAR).
(c) National Instruments (cRIO and PXI HIL).
(5) Maintaining your test benches for program updates and IO changes.
