Multimode Variable-Size Signal

This example shows how to use different operation modes to correspond to different signal sizes.

Open and compile the model named sldemo_varsize_multimode.

This model represents a system that has three operation modes. For each mode, the signal has a different size.

The subsystem named Process receives the variable-size signal, where the size of the signal depends on the operation mode of the system. The Stateflow® chart named Mode Control Logic detects the data signal length changes and responds by issuing mode switching events. For each mode change, the Mode Control Logic chart generates a function-call signal to reset the blocks contained in the Process subsystem.

For a fixed-size signal implementation, open and compile the model named sldemo_varsize_multimodeFixSizeImpl.

In this model, each different mode requires a dedicated processing block, resulting in block duplication.
