Abstract: A system and method for configuring objects in a system diagram to access interfaces of other objects are described. A first node and a second node may be displayed in the system diagram. The second node may implement one or more interfaces, where each interface includes one or more callable functions. An interface wire connecting the first node to the second node may be displayed in response to user input. The system may automatically configure the first node to access at least one of the one or more interfaces of the second node in response to displaying the interface wire.

Abstract: Displaying physical signal routing of a system. A diagram of the system may be displayed. The system may include physical components connected via physical connections and logical components implemented on various ones of the physical components. The diagram may include a plurality of icons connected by wires. At least a first subset of the icons may represent logical elements of the system and wires between the first subset of icons may represent logical connections between corresponding logical elements. User input requesting signal routing information of the system may be received. In response, a signal route corresponding to a first logical connection between a first logical element and a second logical element may be visually indicated.

Abstract: A system and method for creating a graphical program. A function block may be displayed in a graphical program. The graphical program may include a plurality of interconnected blocks which visually indicate the functionality of the program. Additionally, the function block may be operable to perform a first function and may include one or more inputs and one or more outputs. User input specifying an attribute behavior for the function block may be received, e.g., via a menu which allows selection or definition of attribute behaviors, a graphical wizard, or another graphical program, among other methods. The attribute behavior specified for the function block may be usable to determine at attribute of at least a subset of the one or more outputs of the function block based on an attribute of at least one of the one or more inputs to the function block.

Abstract: A pattern may be written to an allocated section of host memory to track how much data has been received in the host memory from a direct memory access controller coupled to a First In, First Out memory. A driver may send the most recently written sample of data from the host memory to an application requesting sampled data. The driver may determine the amount of data written to the host memory by reading the allocated section of host memory and determining the size of a portion of memory, that previously had the pattern, that has been written over with data. The driver may determine if more data than a predetermined amount of data has been written to the host memory or is available to be written to the host memory, and if necessary, send an indication to the application.
