Gestione dei dati di progettazione
Scegliere come archiviare, suddividere e condividere i dati di progettazione dei modelli per progetti di piccole dimensioni e gerarchie di modelli complesse
I dati di progettazione sono l'insieme delle variabili e degli oggetti dati utilizzati per specificare i parametri dei blocchi e le caratteristiche dei segnali, come il tipo e la dimensione dei dati, in un modello di Simulink®. Le opzioni di archiviazione dei dati di progettazione includono il workspace di base di MATLAB®, workspace del modello, file di MATLAB e dizionari dei dati. La scelta di un'opzione di memorizzazione per i dati di progettazione può dipendere da:
Obiettivi di modellazione
Architettura del modello
Tipi di dati
Per scoprire i tipi di dati del modello e come gestire l'archiviazione dei dati per il progetto, vedere Determine Where to Store Variables and Objects for Simulink Models.
Per scoprire come gestire i dati in modo programmatico, vedere Manage Design Data for Simulink Models Programmatically.

Memorizzazione dei dati per i modelli di 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. - What Is Architectural Data?
Use architectural data to define, maintain, and share data across a design hierarchy. - Link MAT File to Model as External Data Source
Use MAT file as an external data source to link it to model for permanent data storage. - Manage Design Data for Simulink Models Programmatically
Connect to a data source, such as a model workspace, base workspace, MAT file, 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.
Memorizzazione dei dati nell'area di lavoro del modello
- 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.
Memorizzazione dei dati nel dizionario
- 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. - Store Shared Data in Architectural Data Section
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. - Link Data Dictionary to Custom Libraries
Share data objects with Simulink block library users using linked data dictionary. - 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.
Memorizzazione dei dati in file esterni
- 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.
Memorizzazione dei dati negli oggetti e nelle variabili
- 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.
