Referencias a modelos
R2026bUna referencia a modelo es una referencia a otro modelo usando un bloque Model. Estas referencias crean la jerarquía del modelo. Cada modelo referenciado tiene una interfaz definida que especifica las propiedades de sus entradas y salidas. Dicha interfaz hace que el comportamiento del modelo referenciado sea independiente de su contexto en la jerarquía de modelos. Las referencias a modelos son ideales para reutilizar el código, las pruebas unitarias, las construcciones paralelas y los componentes de gran tamaño. También pueden reducir la contención de archivos y los problemas de fusión.
Para determinar si los modelos referenciados cumplen sus requisitos de modelado, consulte Component-Based Modeling in Simulink.
Para más información sobre la generación de código para las jerarquías de referencias a modelos, consulte Referenced Models (Simulink Coder).
Para crear una versión lista para ejecutar de un modelo de Simulink® que omita comprobaciones de reconstrucción, consulte Model Publishing (Simulink Coder).
Para ocultar la propiedad intelectual en un modelo, consulte Model Protection (Simulink Coder).
Para realizar pruebas de SIL/PIL en una jerarquía de referencia a modelo, consulte SIL and PIL Simulations (Embedded Coder).

Temas
Determinar cuándo referenciar los modelos
- Component-Based Modeling in Simulink
Consider componentization for large models and multiuser development teams. - Model Reference Behavior and Capabilities
Decide whether to reference one model in another model and how to implement this model reference. - Model Reference Requirements and Limitations
Model references have requirements and limitations relating to features such as reusability, simulation modes, masking, and debugging.
Crear referencias a modelos
- Reference Models
Include a model in another model. - Reference Published Models
Reference ready-to-run published models for faster simulation and code generation. (Desde R2026b) - Reference Protected Models from Third Parties
Use a protected model that you received from a third party. - Convert Subsystems to Referenced Models
Prepare a subsystem for conversion, convert the subsystem to a model, and compare simulation results before and after conversion. - Define Model Reference Interfaces
Ports in the referenced model correspond with ports at the model reference. Signals that cross the model boundary must meet certain requirements. - Inspect Model Hierarchies
Examine the contents, structure, model versions, and logged signals in a model hierarchy.
Configurar referencias a modelos
- Set Configuration Parameters for Model Hierarchies
Configuration parameter values can be different in top models and referenced models. Some configuration parameter values have special requirements or behavior with model referencing. - Conditionally Execute Referenced Models
Execute referenced models conditionally, similar to conditionally executed subsystems. - Referenced Model Sample Times
A referenced model can inherit sample times from the model that references it. - Configure Instance-Specific Values for Block Parameters in a Referenced Model
When you model a reusable component as a referenced model, to configure each instance of the component to use different values for block parameters, create model arguments. - Parameterize a Referenced Model Programmatically
This example shows how to programmatically configure multiple instances of a referenced model to use different values for the same block parameter. - Group Multiple Model Arguments into a Single Structure
This example shows how to programmatically configure multiple instances of a referenced model to use different values for the same block parameter by using structures. - Configure Instance-Specific Data for Lookup Tables Programmatically
When you useSimulink.LookupTableobjects to store and configure lookup table data for ASAP2 or AUTOSAR code generation (for example, STD_AXIS or CURVE), you can configure the objects as model arguments.
Simular jerarquías de modelos
- Choose Simulation Modes for Model Hierarchies
Select the simulation mode for models in a model hierarchy. - Manage Simulation Targets for Referenced Models
A simulation target, or SIM target, is a MEX file that implements a referenced model that executes in accelerator mode. - Share Simulink Cache Files for Faster Simulation
Use Simulink cache files to share build artifacts that let you avoid the cost of a first-time build. - Override Model Reference Simulation Modes
When a top model simulates in normal mode, you can override the simulation mode used for model references without dirtying their parent models. - Reduce Update Time for Referenced Models by Using Parallel Builds
Reduce diagram update time for large model reference hierarchies by using parallel builds. - Simulate Conditionally Executed Referenced Models
Run a standalone simulation of a conditionally executed referenced model. - Simulate Multiple Referenced Model Instances in Normal Mode
Simulate a model that contains multiple instances of a referenced model.
