Introduction > Supported Simulink Interface modes
Using multiple Simulink Interfaces
This section describes using multiple Simulink interfaces.
General remarks
If Simcenter Amesim is the target environment, the interface blocks are completely independent (viewed as standard submodels by Simcenter Amesim). So, the possibilities of mixing different block types or settings on the same Simcenter Amesim sketch are theoretically not limited.
It is possible to use several Simulink models in a single Simcenter Amesim system (and vice-versa), but it is not possible to use the same Simulink model several times in a single Simcenter Amesim system (and vice-versa).
There are as many blocks used in the target environment as independent systems.
Advanced capabilities
| Capability | Supported interface modes for blocks |
|---|---|
| Use N Simulink blocks in Simcenter Amesim | Co-simulation (SL2AMECosim): Simcenter Amesim as Master (Simulink as Slave) |
| Use N Simulink blocks with different solver types (variable/fixed-step) or solver settings in Simcenter Amesim | Co-simulation (SL2AMECosim): Simcenter Amesim as Master (Simulink as Slave)2 |
| Use N Simcenter Amesim blocks in Simulink | Co-simulation (AME2SLCosim): Simcenter Amesim as Slave (Simulink as Master) |
| Model Exchange (AME2SL): Export of Simcenter Amesim model into Simulink | |
| Both Co-simulation (AME2SLCosim): Simcenter Amesim as Slave (Simulink as Master) and Model Exchange (AME2SL): Export of Simcenter Amesim model into Simulink | |
| Use N Simcenter Amesim blocks with different solver types (variable/fixed-step) or solver settings in Simulink | Co-simulation (AME2SLCosim): Simcenter Amesim as Slave (Simulink as Master) |
| In SL2AMECosim, the solver type is always fixed-step but the settings (e.g. step sizes) can be different. Some of these model exchange blocks can be of Black-Box type. |
