Systems and methods may aggregate and organize implicit and explicit initialization, reset, and termination operations defined throughout the hierarchy of an executable. The systems and methods may analyze the model and identify implicit and explicit initialization, reset, and termination operations defined at various hierarchical levels. The systems and methods may aggregate the implicit and explicit initialization, reset, and termination operations into an initialize callable unit, a reset callable unit, and a termination callable unit. The systems and methods may apply optimizations to the callable units, and resolve conflicts. The systems and methods may define a single entry point for each of the initialize, reset, and termination callable units.

Systems and methods for aggregating implicit and explicit event code of executable models

Systems and methods decouple model components from a model execution style for which the model components are created, and the model components may be utilized in parent models having different execution styles. A model component may be partitioned into executable entities, and the entry points of the executable entities and their call styles may be identified. An adaptation layer that includes access points for the entry points may be constructed. The model component, including the adaptation layer, may be included in the model, and connection elements of the parent model may be connected to the access points of the adaptation layer. The execution call styles associated with the connection elements of the parent model may be bound to the execution call styles of the entry points as originally designed. The adaptation layer may manage translation of call styles and may coordinate scheduling of data communication with the model component.

Systems and methods for extracting adjustable attributes of model components

A method may include causing a first model to be executed. The causing the first model to be executed may be performed by a device. The method may further include causing a second model to be executed to simulate a functionality of the first model. The causing the second model to be executed may be performed by the device. The method may further include interacting with a model element, of the second model, associated with implicitly accessing information regarding a state of the first model. The state may be a representation of the first model at a particular simulation time-step. The interacting with the model may be performed by the device. The method may further include accessing, by the model element, information associated with the state of the first model. The accessing the information may be performed by the device.

Graphical modeling for accessing dynamic system states across different components

A programming element is provided that defines model attributes in response to mode change events in a graphical modeling environment. Such definition may involve any signal attribute such as dimensions, data types, complexity and sample times. Events that trigger definition of model attributes may be explicit signaling events generated by other elements, elements within the block diagram programming environment, and elements external from the environment. Implicit events may also trigger definition of model attributes, such as a change of attribute in an input signal.

Mode-switched variable signal attributes in block diagrams

In an embodiment, a technique that may be used to report whether a shared resource in a model is accessed on a mutually exclusive basis by two or more resources in the model. The technique may include identifying the shared resource, determining if the shared resource is accessed on a mutual exclusive basis, generating a result based on the determination, and outputting the result.
