Abstract: A method includes in a system determining a constraint for constraining operation of a portion of a block diagram model, determining if the portion of the block diagram model violates the constraint, and providing a user information based on the violating of the first constraint.

Abstract: Methods and systems for providing a synchronous model in a modeling environment are disclosed. The predetermined operations of the model, such as a transition to a state in a state-based modeling environment, are implicitly synchronized with a signal selected by users, such as a clock signal. The predetermined operations of the model may be synchronized on a rising and/or falling edge of the clock signal. The synchronization of the operations is guarded in which the predetermined operation of the model occurs only on the synchronization signal selected by the users while other operations may occur at any time when the model is activated.

Abstract: In a graphical modeling environment, a template composite signal is provided. The template composite signal groups a plurality of data signals for which one of the attributes for data interpretation are unspecified and provides associated identifying information that identifies the type of data in the template composite signal. Models are simplified by using template composite signals for passing data between graphical objects representing functional entities, without the need for de-grouping the template composite signal. Code may then be generated for the template composite signal.

Abstract: A system and method that includes line connection navigation in a block diagram by highlighting connections through navigable blocks in the diagram, edit-time label propagation along connections and through navigable blocks that can propagate labels through their ports, API to define navigability between block ports, and displaying implied connections between blocks.

Abstract: In one embodiment, a data element is passed between a first block and a second block of a block diagram during execution of the block diagram. The first block and the second block negotiate use of a particular input/output (I/O) type from a plurality of available I/O types. The particular I/O type is used with at least one I/O buffer employed in passing the data element between the first block and the second block. The first block may produce a signal representing the data element. The signal is received at the I/O buffer and the data element stored according to the particular I/O type. Subsequently, the data element may be read from the I/O buffer by the second block, which performs an operation, the result of which is used when the block diagram is executing.

Abstract: Method and systems are provided for representing interfaces between electronic components of a computational hardware device in a graphical model and automatically generating code from the graphical model to implement one or more component interfaces in the computational hardware device. A graphical modeling environment provides for the definition of interface boundaries to represent component interfaces between electronic components associated with partitions of a graphical model design. A code building tool automatically generates code from the graphical model to build executable instructions to run the component interfaces on the electronic components of the computational hardware device.

Abstract: The present invention relates to integration of an external processor capable of execution of one or more functions into a block diagram model environment such that the block diagram model environment can make function calls directly into the external processor without the need for traditional wait loops or handshaking means. Furthermore the results of the function that was called in the external processor can be passed to the block diagram model environment from the external processor.

The graphical model and the remote auxiliary tool are executed synchronously. At least one of an execution result or a remote auxiliary tool result is output to at least one of a display device, a storage device or a destination device.

Abstract: A method and system are provided for generating code from a graphical model in a graphical modeling environment. The graphical model includes at least one signal having a data size, a data dimensionality, or both that can vary from a first time instance to a second time instance as the model executes. The size and dimensionality of the signal can vary without the use of a graphically rendered connection to convey the size and dimension information to a block associated with the signal.
