Gérer les données du design
Choisir comment stocker, partitionner et partager les données de design des modèles pour les petits projets et les hiérarchies de modèles complexes
Les données de design correspondent à l'ensemble des variables et objets de données que vous utilisez pour spécifier les paramètres des blocs et les caractéristiques des signaux, tels que le type de données et la dimension, dans un modèle Simulink®. Parmi les options de stockage disponibles pour les données de design, citons l'espace de travail de base de MATLAB®, l'espace de travail de votre modèle ou un dictionnaire de données. Le choix de l’emplacement de stockage de vos données de design peut dépendre des éléments suivants :
Objectifs de la modélisation
Architecture de modèles
Types de données
Pour en savoir plus sur les types de données de modèles et sur la manière de gérer le stockage des données pour votre projet, consultez Determine Where to Store Variables and Objects for Simulink Models.
Pour apprendre à gérer les données de manière programmatique, consultez Manage Design Data for Simulink Models Programmatically.

Stockage de données pour les modèles Simulink
- Determine Where to Store Variables and Objects for Simulink Models
Simulink data are objects and variables that you create in workspaces such as the base workspace or a data dictionary. Choose a technique to permanently store that data. - Manage Design Data for Simulink Models Programmatically
Connect to a data source, such as a model workspace, base workspace, or data dictionary, then use a common set of functions to manage the data. - Create, Edit, and Manage Workspace Variables
Workspace variables enable you to share information, such as parameter values and data types, between blocks and models. Use different tools and techniques to create and manipulate workspace variables. - Edit and Manage Workspace Variables by Using Model Explorer
Find out which workspace variables are used by a model or block, find blocks that use a variable, find unused variables, and rename a variable everywhere it is used by blocks. Save and load variables from a separate file.

- Model Workspaces
Place variables and objects that a model uses in a workspace that only the model can access. - Change Model Workspace Data
When you store data in a model workspace, you choose a data source, such as the model file or an external MAT-file. To modify the variables at the source, you use a different procedure depending on the type of source that you selected. - Specify Source for Data in Model Workspace
Store variables and objects that a model uses in the model file or in a separate file. Optionally, store the variables and objects as code that you can modify.
Stockage de données dans un dictionnaire
- What Is a Data Dictionary?
Use a data dictionary to store external data for a model. - Import and Export Dictionary Data
Migrate data between a data dictionary and a MAT-file or MATLAB script file. - View and Revert Changes to Dictionary Data
Use a data dictionary to inspect and manage changes to model data. - Graphically Manage Shared Interfaces, Data Types, and Constants
To share interfaces, data types, and constants across components and compositions modeled in Simulink, use the Architectural Data section of a data dictionary. - Migrate Models to Use Simulink Data Dictionary
Store variables and objects in data dictionaries. - Partition Dictionary Data Using Referenced Dictionaries
Create referenced dictionaries to store subsets of the data that a model or model hierarchy uses. - Partition Data for Model Reference Hierarchy Using Data Dictionaries
Compose a dictionary hierarchy based on a model reference hierarchy. - Attach Data Dictionary to Custom Libraries
Share data objects with Simulink block library users using attached data dictionary. - Attach Data Dictionary to Subsystem Reference
Use a Simulink data dictionary with child blocks and instances of your subsystem file. - Enumerations in Data Dictionary
Store enumerated type definitions and enumerated data in a data dictionary. - Store Data in Dictionary Programmatically
Use scripts and the command prompt to create and interact with data dictionaries.

- Create External File Adapter for Loading Variables into Simulink.SimulationInput Object
Define a custom file adapter that can be used by Simulink to load variables from an external file source into aSimulink.SimulationInputobject.
Stockage de données dans des objets et des variables
- Data Objects
Specify properties for parameters, signals, and states, including parameter values, outside of a block diagram by using external data objects. - Symbol Resolution
You can control how blocks in a model resolve symbols to variables and objects that you create in workspaces. - Define Data Classes
Customize the way your model interacts with data (signals, parameters, and states) by creating your own class of data object. - Upgrade Level-1 Data Classes
Simulink no longer supports level-1 data classes. You must upgrade data classes that you created using the level-1 data class infrastructure, which was removed in a previous release.
