  • Patent number: 11593540
    Abstract: Systems and methods analyze an executable simulation model to identify existing concurrency, determine opportunities for increasing concurrency, and develop proposed modifications for realizing the opportunities for increased concurrency. The systems and methods may label locations at the simulation model where concurrency exists, and provide information regarding the proposed modifications to increase the model's concurrency. The systems and methods may modify the simulation model if the additional concurrency is accepted. The systems and methods may operate within a higher-level programming language, and may develop the proposed modifications without lowering or translating the simulation model to a lower abstraction level. The systems and methods may also undo a modification, rolling the simulation model back to a prior design state. Accepting the proposed modifications may cause the simulation models to execute more efficiently, e.g., faster.

  • Patent number: 10423390
    Abstract: A system and method may automatically generate computer programming code for an executable model having messaging semantics. The executable model may define messages that have fixed payloads, and that persist for only a determined time interval of a total execution or simulation time of the model. The model may establish message queues for storing messages. The standalone code may include code that establishes message services including the creation of message queues. The generated code may be compiled and deployed on a target device for execution.

  • Patent number: 9389836
    Abstract: In an embodiment, in a graphical modeling environment, users may create models that can be executed. Within the graphical modeling environment, users may use implicit iterator systems to manage multiple iterations of systems whereby the indexing of input and output signals may be defined by a user and state may be managed for an iteration.

  • Patent number: 9304840
    Abstract: A system and method may generate executable block diagrams in which at least some of the blocks run in accordance with message-based execution semantics. A message may include an input data payload that does not change over time, and the message may persist for only a determined time interval during execution of block diagram. A message-based execution engine may control execution of message-based blocks in which a source block may generate a message at a particular point in time, the message may be sent to one or more destination blocks triggering execution of those blocks, and the message may be destroyed on or after a determined time interval. Other execution domains, such as a time-based or state-based execution domain, may be provided, and the system may implement a hybrid execution model.

  • Patent number: 9195439
    Abstract: Exemplary embodiments support multi-threaded subgraph execution control within a graphical modeling or graphical programming environment. In an embodiment, a subgraph may be identified as a subset of blocks within a graphical model, or graphical program, or both. A subgraph initiator may explicitly execute the subgraph while maintaining data dependencies within the subgraph. Explicit signatures may be defined for the subgraph initiator and the subgraph either graphically or textually. Execution control may be branched wherein the data dependencies within the subgraph are maintained. Execution control may be joined together wherein the data dependencies within the subgraph are maintained. Exemplary embodiments may allow subgraphs to execute on different threads within a graphical modeling or programming environment.

  • Patent number: 9063741
    Abstract: 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.

  • Patent number: 9003360
    Abstract: In an embodiment, a specification of a configuration subgraph is received. The configuration subgraph may graphically specify an attribute for an element in a block diagram model. A relationship may be established between the configuration subgraph and the element. The configuration subgraph may be evaluated to produce a result. The result may be used to configure the attribute of the element during or prior to a compilation of a dynamic portion of the block diagram model. The configuration subgraph may not be used during an execution of the dynamic portion of the block diagram model.
