• In AMESim
• Add Simulink Interface in the AMESim model
• Run the AMESim model off-line (passing from the parameter mode to the
simulation mode – thus generating the s-function)
• Generate files for real-time simulation
• In Simulink and RT-LAB
• Add s-function block and specify the C source file name and parameters
• Run the model offline with fixed-step solver and verify results
• Run the model in real-time and compare the results

• OPAL-RT and LMS have collaborated for about 6 years
• Enable real-time simulation of these models on OPAL-RT platforms.
• AMESim has tools that allow the user to adapt models for real-time simulation
by optimizing model reduction.
• This integration allows powerful real-time plant simulation capabilities for HIL
• Open approach that allows customers to use modeling tools of their preference
• Tools can be used together for a complex system such as a hybrid bus, for
which HIL is absolutely critical for integration testing of multiple ECU
