This instance exhibits how to create and run a back-to-back test on a complete mannequin to compare the results of regular mode simulation and software-in-the-loop (SIL) simulation. Back-to-back testing, or equivalence testing, checks whether or not the generated code produces the same outcomes as the model simulation.

Select Record coverage for system beneath test and Record protection for referenced fashions to enable coverage collection. Use the default values for the places to save the test data and the generated exams. In the Test Inputs tab, use the default setting, Use component enter from the top model as take a look at enter.
