Simulation & Toolchain
Before concepts are technically implemented, they undergo comprehensive simulation at CME. This shortens development processes, reduces costs and achieves maximum efficiency.
At CME, simulation is not a downstream verification step but an integral part of the development process. Already in the concept phase, we rely on model-based simulation to validate design decisions, identify risks early and minimize the number of physical prototypes.
