Reliably validating electronic control units on hardware-in-the-loop (HiL) systems requires the exact replication of associated sensors and actuators if different test scenarios are to be mapped. In addition to in-depth expertise in the area of sensor and actuator models, MicroNova has many years of experience in scenario and environment modeling – both in the area of automotive testing and in the testing of wind turbines.
MicroNova Consulting offers different levels of abstraction for modeling to simulate ECUs: from the simulation of bus communication for a non-existent ECU to a completely virtual ECU (electronic control unit) with the goal of enabling virtual ASIL-relevant tests.
The software and system house MicroNova has been developing HiL systems itself for many years. This competence naturally also has a positive effect on the quality of the models. Systematic modularization, which has been incorporated into the entire NovaCarts product range, significantly shortens model compilation times. This means that a separate model is created for each control unit and each function, which can be run independently directly on the HiL simulator – without the need for costly recompilation of the entire model. In addition, no special hardware is required for modeling. Modifications to the models can also be carried out easily and with minimum time loss.
Besides the development time, the runtime of a model is crucial in order to achieve the desired real-time behavior. We accomplish this both by the type of modeling and by adapting the computing hardware, for example co-simulation on optimized simulation computers or different constellations of FPGAs.
These advantages are particularly evident in the NovaCarts HiL systems, as the entire architecture is designed to efficiently replicate control units. Of course, we also have many years of experience in integrating our models into the test environments of all common hardware vendors.

MicroNova offers flexible basic models, which we tailor to exactly meet the focus of your application. If necessary, further modifications can be easily made at any time. We also develop special models for a huge range of applications, for example for the exact determination of a battery’s status (state-of-health, SoH) using electro-impedance spectroscopy or for conversion between two buses (RDB and ADTF).
Our service team manages model integration with the test infrastructure directly at the client’s site. This includes commissioning in the test system together with the control unit and other components. Furthermore, we will gladly handle the integration of real control units with the simulation on your behalf, as this requires consideration of a large number of interfaces and interrelationships within the overall system.
Benefit from over 30 years of experience in model creation as well as the maintenance and extension of customer models. MicroNova consultants have extensive experience in agile software development gained from numerous projects. Our internal hardware development is also agile. In modeling, our experts and customers are usually organized together in scrum teams.
MicroNova consultants support your development processes on site. Individual project tasks can also be outsourced to nearby countries.
