Verify Numerical Equivalence with CGV

Before verifying numerical equivalence:

• Configure your model for SIL or PIL simulation.

• Use the cgv.Config class of the CGV API to verify the model configuration for SIL or PIL simulation.

• Configure your model for code generation. For more information, see Configure Model for Code Generation Objectives by Using Code Generation Advisor.

• Save your model. If you modify a model without saving it, CGV can issue an error.

To verify numerical equivalence:

• Set up the tests for the first execution environment. For example, simulation.

• Use run to run the tests for the first execution environment.

• Set up the tests for the second execution environment. For example, top-model PIL.

• Use cgv.CGV.run to run the tests for the second execution environment.

• Use getOutputData to get the output data for each execution environment.

• Use getSavedSignals to display the signal names in the output data. (optional)

• Build a list of signal names for input to other cgv.CGV methods. (optional)

• Use createToleranceFile to create a file correlating tolerance information with output signal names. (optional)

• Use compare to compare the output signals of the first and second execution environments for numerical equivalence.

Note

Simulink^® Test™ is a separate product that provides additional capabilities for SIL and PIL testing, for example, test sequence construction and test management.
