Analyser les résultats de simulation

Inspecter les données avec des curseurs et des visualisations personnalisées, rejouer les résultats de simulation et comparer les données de ces simulations

Vous pouvez utiliser Simulation Data Inspector pour inspecter et comparer les données de plusieurs simulations. Par exemple, vous pouvez vérifier si la différence entre deux signaux est située dans une certaine plage de tolérance du design. Pour en savoir plus, consultez la rubrique Simulation Data Inspector.

The Inspect pane of the Simulation Data Inspector shows three subplots. The subplots show time plots of data gathered from three runs of the model sldemo_autotrans. The first subplot shows the EngineRPM signals from all three runs. The second subplot shows the ShiftLogic signals from all three runs. The third subplot shows the VehicleSpeed signal from all three runs.
