Use the Schedule Editor to schedule the function-call components for simulation. This strategy is useful when you want to set the order of execution for function-call components and view data dependencies between components.
Create a new Simulink® model.
Add a Model block that references the export-function model.
Specify function-call events using the Schedule Editor.
Specify data inputs.
Run a simulation.
To create the model for this example, see Create Export-Function Model.
A Simulink test model is used only for simulation. After simulation testing, generate code from the export-function model, and then manually integrate exported function code with an externally coded scheduler. Referencing an export-function model from a Model block allows the addition of function-call events and logging of data signals for testing without changing the model itself.
Create a new Simulink model.
On the Modeling tab and from the Setup section, select Model Settings .
In the left pane of the Configuration Parameters dialog box, select Solver. In the right pane, select the Solver details arrow to display additional parameters. Select the check boxes for Treat each discrete rate as a separate task and Automatically handle rate transition for data transfer.
Add a Model block to your model
On the Modeling tab, select the Design section, and then select Property Inspector .
In the Model name box, enter
export_function_model. Select the Schedule
rates check box. From the Schedule rates drop-down
Add Outport blocks to the output_100ms and output_10ms ports on the Model block.
Add a Sine Wave block to provide data input. Set
2 and Sample
0.01. Connect the block to the
input_10ms input port on the Model block.
Use the Schedule Editor to provide function-call events by defining time-vectors that indicate when events occur for root-level function-call Inport blocks
Open the Schedule Editor. On the Modeling tab and from the Design section, select Schedule Editor . The Schedule Editor partitions the function-call Inport blocks and names the partitions using the block names.
Select the function_call_2 partition. In the Hit Times box,
enter a matrix with values that begin at 0, periodically increase by 0.01 to 10. You
could also test asynchronous behavior by entering a matrix with random values that are
Select the function_call_1 partition. In the Hit Times box, enter a matrix with values that begin at 0, increase by 0.1 to 10.
Simulate the export-function model to test and observe its behavior before generating code.
Verify the configuration parameters for Solver Type is set to
Fixed-step, Solver set to
continuous states) or
auto (Automatic solver
selected), and Fixed-step size (fundamental sample
time) is set to
Set up logging of data signals. Right-click output port signals and select the Log selected signal check box.
On the Simulation tab, select the run button .
Open the Simulation Data Inspector by clicking the toolstrip icon .
After you test your model, you can generate code for the functions. See Generate Code for Export-Function Model.
