SIL/PIL Manager Verification Workflow - MATLAB & Simulink (original) (raw)

Main Content

The SIL/PIL Manager is an app that provides a simplified workflow for verifying generated model code.

Open the App

To open the SIL/PIL Manager in the Simulink® Editor, on the Apps tab, click SIL/PIL Manager. Or, on the C Code tab in the Embedded Coder® app, select > .

Select the Mode

In the Mode section, specify the simulations that you want the app to run. You can select:

• Automated Verification — The app runs two simulations back-to-back. The first simulation is a model simulation in normal, accelerator, or rapid accelerator mode. The second simulation is a software-in-the-loop (SIL) or processor-in-the-loop (PIL) simulation. After the second simulation is complete, the app uses the Simulation Data Inspector to compare the results of the simulations.
  For the first simulation, if the model contains a Model block with the Simulation mode block parameter set to Software-in-the-loop (SIL) orProcessor-in-the-loop (PIL), at the start of the simulation, the app changes the block parameter toNormal. At the end of the simulation, the app reverts the block parameter to the previous value.
• Simulation Only — The app runs a model simulation in normal, accelerator, or rapid accelerator mode.
  If the model contains a Model block with theSimulation mode block parameter set toSoftware-in-the-loop (SIL) orProcessor-in-the-loop (PIL), at the start of the simulation, the app changes the block parameter toNormal. At the end of the simulation, the app reverts the block parameter to the previous value.
• SIL/PIL Simulation Only — The app runs a SIL or PIL simulation.

Prepare the Model

In the Prepare section:

• Specify the numeric testing approach.
• Specify the main configuration parameters.
• Enable or disable code execution profiling and code coverage analysis.

This table shows how the field settings in the Prepare section control simulations that the app runs.

If you click Settings, the app provides these controls:

• Under SIL/PIL Settings:
  • Settings — DisplayVerification parameters in the Configuration Parameters dialog box.
  • Portable Word Sizes — Select or clearEnable portable word sizes. For information about how you can generate code that supports compilation on your development computer, see Configure Hardware Implementation Settings.
  • Debugging — Select or clearEnable source-level debugging for SIL or PIL.
• Under Coverage:
  • Coverage Settings — DisplayCoverage parameters in the Configuration Parameters dialog box.
  • Coverage Collection — Enable or disable code coverage. If code coverage with Simulink Coverage™ is enabled, clicking the button togglesCovEnable between'on' and 'off'. For more information, see Code Coverage.
• Under Time Profiling:
  • Task Profiling — Select or clearMeasure task execution time.
  • Save Options — If Task Profiling is selected, clicking the button sets the Save options configuration parameter to Summary data only,All data, andMetrics only cyclically. IfTask Profiling is not selected, the button is dimmed.
  • Functions — Clicking the button sets the Measure function execution times configuration parameter to Off,Coarse (referenced models and subsystems only), and Detailed (all function call sites) cyclically.
    For more information, see Configure Code Execution Profiling and Control Profiling Granularity.
• Under Stack Profiling, Stack Profiling— Select or clear Measure task stack usage. For more information, see View and Compare Stack Usage Metrics.

If you click Monitor Signals, the app provides these controls:

• Under Monitor Signals:
  • Log Selected Signals — Enable signal logging for model simulation.
  • Make Selected Signals Testpoints — Required for signal observation in SIL or PIL simulations.
• Under Logging Options:
  • Signal Logging — Set theSignalLogging configuration parameter to 'on' or 'off', which enables or disables signal logging to the MATLAB® workspace and signal streaming to the Simulation Data Inspector.
  • State Logging — Set theSaveState configuration parameter to'on' or 'off', which enables or disables state data logging to the MATLAB workspace and state data streaming to the Simulation Data Inspector.
  • Signal Table — Display theSignals tab in the Model Data Editor.
  • Configure Logging — Display theData Import/Export parameters in the Configuration Parameters dialog box.
  • Normal Mode Visibility — Open the Model Block Normal Mode Visibility dialog box.

To monitor component signals and state data and compare values from the model and SIL or PIL simulations:

1. For each signal that you want to log:
   1. In the Simulink Editor, select the signal.
   2. On the SIL/PIL tab, clickMonitor Signals. From the gallery, select these options:
      • Log Selected Signals
      • Make Selected Signals Testpoints
      • Signal Logging
2. To log state data, from the Monitor Signals gallery, select State Logging.
3. If the Language configuration parameter isC++, in the Code Mappings editor, set the Data Visibility for the signals, states, and internal data model element categories topublic.

For more information, see Log Signals of a Component.

Run Automated Verification, Model Simulation, or SIL/PIL Simulation

With one click, you can run back-to-back model and SIL or PIL simulations. You can also run individual simulations.

If you select the Automated Verification mode, theSIL/PIL tab displays the Run Automated Verification section. To run back-to-back simulations:

1. In the Stop Time field, specify the simulation time. For the Automated Verification mode, you cannot specify inf.
2. Click Run Verification.

If you select the Simulation Only or SIL/PIL Simulation Only mode, the SIL/PIL tab displays the Run section. In this case, the toolstrip provides additional controls:

• Fast Restart — Click to turn on fast restart. For theSimulation Only mode, the compiled model does not contain components in SIL or PIL mode.
• Step Back and Step Forward — You can configure stepping through a simulation by using the Simulation Stepping Options tool. To open the tool, clickStep Back, and then select Configure Simulation Stepping.
  Simulation stepping is not available if the mode is SIL/PIL Simulation Only and System Under Test is Top model.

To run an individual simulation:

1. In the Stop Time field, specify the simulation time.
2. Click Run Simulation or Run SIL/PIL.

Analyze Results and Export Test Cases

In the app Results section, you can analyze results. If you click Compare Runs or Data Inspector, the app provides these controls in the Results gallery.
