摘要： Methods and systems are provided for partitioning and distributing the model processing of a graphical model to provide an executable form of the graphical model. The methods and systems determine tasks of the model processing that can be processed separately and concurrently from other tasks. A distribution scheme for distributing the model processing tasks is determined that considers the characteristics of the model processing tasks in view of the characteristics of available computing resources. Variations of partitioning and distributing the model processing tasks can be determined to provide for distributed processing in an optimized or desired manner. The results of the distributed processing of the model processing tasks are obtained and combined to provide an executable form for the graphical model.

摘要： A device may receive a state chart generated via a technical computing environment. The state chart may include a first state block and a second state block, and the second state block may include textual code understood by a textual engine of the technical computing environment. The device may receive, in association with the second state block, an implicit event command that references an event associated with the first state block, and may initiate execution of the state chart. The device may receive, during execution of the state chart, an indication of occurrence of the event associated with the first state block, and may initiate the second state block based on the indication.

摘要： Systems and methods automatically construct a realization of a model from an available set of alternative co-simulation components, where the realization meets one or more objectives, such as fidelity, execution speed, or memory usage, among others. The systems and methods may construct the realization model by setting up and solving a constrained optimization problem, which may select particular ones of the alternative co-simulation components to meet the objectives. The systems and methods may configure the realization, and execute the realized model through co-simulation. The systems and methods may employ and manage different execution engines and/or different solvers to run the realization of the model.

摘要： A device may determine temporal ages of a first signal and a second signal provided in a graphical model generated in a technical computing environment, where the first signal is different than the second signal. The device may determine whether the temporal age of the first signal is equivalent to the temporal age of the second signal at a particular block of the graphical model. The device may either display an indication that the first signal is synchronized with the second signal when the temporal age of the first signal is equivalent to the temporal age of the second signal, or may display another indication that the first signal is not synchronized with the second signal when the temporal age of the first signal is not equivalent to the temporal age of the second signal.

摘要： 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.

摘要： A device may receive, from a user, a selection of one of a graphical representation of a data store included in a model or a string of text that identifies a variable associated with the model. The device may provide, based on the selection, a user interface for providing pattern information associated with the data store. The device may receive, via the user interface, the pattern information associated with the data store. The pattern information may identify one or more elements included in the model and a pattern associated with the one or more elements accessing the data store during an execution of the model. The device may analyze the model based on the pattern information and may output a result. The result may indicate whether the model accesses the data store in compliance with the pattern.
