Abstract: A device may receive model information that describes a model and external system information that describes an external system that is different than the model. The model information may identify a first set of signals, associated with the model, that are incompatible with the external system. The external system information may identify a second set of signals, associated with the external system, that are incompatible with the model. The device may generate interface code based on the model information and the external system information. The interface code, when executed, may permit the model and the external system to interact using the first set of signals and the second set of signals. The device may execute the interface code to transform the first set of signals to the second set of signals and to transform the second set of signals to the first set of signals.

Abstract: A device may receive information specifying a physical time delay of a computational node of a first computational graph. The first computational graph may include a group of computational nodes that are connected in a particular manner, and may represent at least a portion of a dynamic system. The device may further add an abstract node to a second computational graph based on the received information. The abstract node may correspond to the computational node and may implement the physical time delay when the second computational graph is executed. The second computational graph may include a group of abstract nodes that are connected in the particular manner. The device may also execute the second computational graph, and may obtain one or more behavioral characteristics of the at least the portion of the dynamic system based on executing the second computational graph.

Abstract: In an embodiment, a method for interactively changing allocation of an application including multiple algorithm components executing on a heterogeneous target environment (HTE) provides a user interface in a co-simulation design environment. The user interface is associated with the application having multiple algorithm components executing on the HTE that includes multiple computing devices with different processing capabilities. The method also sets attributes of the allocation scheme of the application using the user interface. The setting occurs when the application is executing. The method further receives data associated with the executing of the application in the co-simulation design environment when the application is executing subsequent to the setting of the attributes of the allocation scheme.

Abstract: The present invention provides a set of blocks for creating device drivers. Since, for most computational devices, device driver code to configure and control an I/O interface may be decomposed into a small finite number of common software functions, by providing a block set comprising blocks representing the finite number of common software functions, custom device drivers can be created for any number of devices. Thus, by providing a set of generalized device driver blocks that can be parameterized by the user, specific instances of custom device drivers can be created as needed. Processor and device specific driver code can then be generated from the custom device driver.
