FMI & Co-simulation

Bert Van Acker, Cláudio Gomes and Joachim Denil

The Modern Car

• Complexity– 40+ subsystems

• Competitive Market• Concurrent Development– Late Integration Nightmare

• Distributed Development– OEM suppliers– Late Integration (due to IP)

Functional Mock-up Interface (FMI)

• Xml + C Representation for Models– Standard– Tool Independent– Black box*

• Earlier integration of OEM– IP Protection (dll)– Reduced cost & TTM

• (Co-)Simulation* www.fmi-standard.org

Co-Simulation

* www.cvel.clemson.edu/

• Coordination

• HiL Simulation

• Hybrid Simulation• Semantic Adaptation

Specific Master Generation

• Specific Master• Efficiency• Correct co-

simulation
