Sources

Fournir des données d'entrée pour la simulation avec des blocs qui définissent et génèrent des signaux ou chargent des données de signaux

Utilisez les blocs de la bibliothèque Sources pour fournir des signaux en entrée de la simulation.

Générez des signaux dans votre modèle avec des blocs comme Sine Wave et Constant.
Chargez les données de signaux de l'espace de travail ou d'un fichier avec des blocs comme Playback, From Workspace, From File et From Spreadsheet.
Créez et modifiez des signaux avec des blocs comme Signal Editor.
