Model Analysis with Simulink Design Verifier Software

Simulink Design Verifier software is an efficient analysis tool that explores the simulation behavior of a Simulink model. It searches the possible values of model inputs and block parameters to find a simulation that satisfies test objectives. The software also proves model properties and generates examples of violations.

Such analysis always begins with the initial configuration of the model and can span an arbitrary number of time steps. Generally, there is an infinite number of paths through the model because the values of inputs are independent from one time step to the next, and there is no fixed limit to the number of time steps.

If the software finds no way to reduce the search space, it would continue its analysis indefinitely. Thus, the software limits the analysis by tracking the persistent information in the model such as discrete states, data-store memories, and persistent variables.

After an analysis explores all possible inputs and parameters from all possible configurations, the results equal those of a complete search of every possible infinite sequence of inputs parameters.
