The graphical operation when performed may establish a relationship between the first graphical element and one or more other graphical elements of the plurality of graphical elements that are compatible with the graphical operation. Two or more graphical elements of the plurality of graphical elements that are compatible with the graphical operation and one or more characteristics associated with the first graphical element may be identified. A visual indication may be provided on the display device. The visual indication may indicate that the identified plurality of graphical elements is compatible with the graphical operation.

Abstract: A mechanism to dynamically vary the amount of delay for an event-generated function call is discussed. The event causing the generation of the function call may be a signal-based event, function call event or some other type of event. A function call generating delay component is inserted into a DES model and dynamically adjusts the amount of delay to apply prior to generating and transmitting the function call to an intended target component. The function call generating component reads a value from an input port in determining the amount of delay. The identified value at the input port may be a signal value or an attribute associated with an event entity received at the port.

Abstract: Methods and systems for partitioning objects in modeling environments are disclosed. The modeling environments enable users to partition an object (parent object) to include other objects (child objects). The parent object may reference the child objects (referenced objects). The child objects may be subsystems in the hierarchy of the parent object or modules (or units) in the partitioning of the parent object. The child objects may be encapsulated so that changes in the parent object do not affect the child objects. The partition of the parent object may allow users to load and compile the parent object incrementally. The partition of the parent object may also allow users to generate code for the parent object incrementally.

Abstract: Mediums, methods, and systems are provided for efficiently logging data. A model may include one or more logging points which process data, the data being stored in a log associated with the logging point. The logging point may request that a logging object store the data point. The logging object may include a reference to a vector for storing the data point. When two or more logging objects are associated with the same logged data points, the two or more logging objects may share the same vector. If an object logs a point which is not present in a shared vector, the object may update the object's reference so that the object references a different existing vector, or the object may create a new vector. The vectors may be compressed and/or made circular to achieve improved efficiency.

Abstract: A configurable class system for an application author working in an application development environment that automates the handling of undo, redo and logging operations is discussed. The configurable class system removes the burden from the application author of having to custom manage undo, redo and logging information during application writing by providing the necessary mechanisms to every application object created. The configurable class system also allows the application author to handle exceptional state changes in an application by configuring the underlying base classes provided by the configurable class system. Additionally, the embodiments of the present invention enable the application author to customize the compression of a series of identified operations by selecting the type of operations that are to be compressed and the manner in which the compression is to occur.

Abstract: The present invention provides a state diagramming environment in a computing device that enables the conversion of a state diagram into a hardware description language. To achieve this conversion, the present invention generates an intermediate representation of the state diagram. The intermediate representation is checked against a set of predefined restrictions for compliance. The state diagramming environment converts the intermediate representation of the state diagram into a hardware description language, such as VHDL or Verilog.

Abstract: A system and method of exposing debugging information in a graphical modeling and execution environment is disclosed. The present invention allows a user to view debugging information in the same window as the graphical view of the model being executed. Debugging data is associated with relevant components of the model displayed in the graphical view. A separate execution list view shows the methods called during the execution of the block diagram in the current time step up until the current point in execution. User-set breakpoints and conditional breakpoints may be set in both the model view and the execution list view. Values may be obtained for all of the displayed methods. The debugging tool may be implemented by using it in conjunction with a graphical modeling and execution environment, such as a block diagram environment or state diagram environment.

Abstract: A method of saving portions of a simulation or execution engine image at various points in a simulation or execution is disclosed. The saving of the simulation or execution context in addition to the more traditional saving of the system state information enables the restoration of a simulation or execution that is capable of producing, in a subsequent simulation or execution of a block diagram continuing from the point of the saved simulation or execution, results that are identical to those of the initial simulation or execution. The ability to restore more than just system state variables enables a user to run multiple variations of a simulation from a given point without having to replicate the simulation up until the point of the saved initial simulation, and the ability to run multiple iterations of a block diagram execution in a non-simulation execution from a given point without having to replicate the execution of the block diagram up until that point.

Abstract: The present invention provides a method and system for interfacing with a model regardless of model type. An abstract interface is provided for interfacing a model. The abstract interface is compatible with a plurality of model types. A call can then be made to a dynamic model via a method specified by the abstract interface. Data is then received from the dynamic model in response to the call. In certain embodiments the abstract interface is an application programming interface (API).

Abstract: Systems and methods are provided for detecting an action providing input associated with an element of a user interface and/or graphical model, and providing an indicator to indicate the action has been detected. The user interface and graphical model may provide one or more elements that may be editable or otherwise changeable by a user or programmatically via executable instructions. The action may provide input that may change a value of the editable element of the user interface or alter an element of the graphical model. Upon detection of the action, the present invention provides an indicator in the user interface or the graphical model in a manner associated with the detected changed element. The indicator may be a visual indicator or may be any other sensory type of indicator, such as a sound, force, or tactile indicator. As such, the indicator provides a prompt to a user that one or more elements of the user interface or graphical model may need to be saved, applied, or any changes canceled.
