Simulation and visualisation for optimum results

Before concepts for newly developed electronics products are technically implemented, they undergo a test in our simulation area. In this way we speed up development processes and reduce the outlay for mechanical measurements.  To ensure that our simulations are realistic we use appropriate tools such as Matlab/Simulink.
