Abstract: A method for modeling a set of observed data comprises selecting a reference model and an alternative model as possible descriptions of the set of observed data, and storing an index function for measuring fit of models to data. The method further includes performing, by one or more processors, a simulated threshold-fitting for a first of the two models, deriving an initial simulated index for the second model for fitting the second model to the simulated data, and deriving an initial boundary for simulated index difference including calculating a difference between the threshold-fit simulated index for the first model and the initial simulated index for the second model. The method further includes determining, based on a comparison, whether to update a counter used in calculating a simulated p-value, and selecting, based on the simulated p-value, one of the reference and alternative models for modeling the set of observed data.

The device creates a block identifier for each block of the models based on the model information, and determines one or more blocks that connect to each block of the models, based on the model information. The device creates identifiers for the one or more blocks that connect to each block of the models, and assigns weights to the identifiers based on sources of the models or a number of times the one or more blocks connect to each block of the models. The device ranks the identifiers based on the weights assigned to the identifiers, and store the ranked identifiers and the block identifiers in a data structure.

Abstract: A system and method of exposing debugging information in a graphical modeling and execution environment is disclosed. The present invention allows a user to view debugging information in the same window as the graphical view of the model being executed. Debugging data is associated with relevant components of the model displayed in the graphical view. A separate execution list view shows the methods called during the execution of the block diagram in the current time step up until the current point in execution. User-set breakpoints and conditional breakpoints may be set in both the model view and the execution list view. Values may be obtained for all of the displayed methods. The debugging tool may be implemented by using it in conjunction with a graphical modeling and execution environment, such as a block diagram environment or state diagram environment.

Abstract: In an embodiment, a mechanism for visualizing a graphical model in three dimensions is discussed. An executable graphical model is obtained that includes a hierarchy of model levels that include a top level. The hierarchy includes multiple components. A three-dimensional (3D) view of the graphical model is displayed that provides views of a first and second component at a first and second depth. A graphical indicator is generated in the view of the top level of the graphical model that is associated with the first component and also generated in the view of the second component. A control alters a user perspective of a view that includes at least one of the components in the graphical model.

Abstract: One or more computer-readable storage media for storing computer-executable instructions executable by processing logic is provided. The media storing one or more instructions that when executed by the processing logic causes the processing logic to receive data in a first format for conversion to a second format different than the first format, wherein the data includes information having a first type and information having a second type and display the data in the first format via a graphical interface. One or more translation rules are received relating to processing the information having the first type or the information having the second type. The one or more translation rules are pre-applied to the data in the first format. Effects of the pre-applied rules on the displayed data are displayed via the graphical interface. The data in the first format is converted to the data in the second format based on the one or more translation rules.

Abstract: A device receives information that identifies a parameter associated with a masked block that represents elements of a block diagram model that, when executed, simulates a behavior of a system. The masked block is associated with a first user interface that allows a value of the parameter to be specified for the masked block. The device receives an indication that the parameter is to be associated with a derived block that represents the elements of the block diagram model. The derived block inherits one or more properties from the masked block. The device creates the derived block, and associates the derived block with the parameter and a second user interface that allows a value of the parameter to be specified for the derived block. The device outputs or stores information that identifies the parameter, the derived block, and the association between the parameter and the derived block.

Abstract: A system and method optimizes hardware description generated from a graphical program or model having oversampling constraints automatically. The system may include a streaming optimizer, a resource sharing optimizer, a delay balancing engine, and a global scheduler. The streaming optimizer may transform vector data paths to scalar or smaller-sized vector data paths. The resource sharing optimizer may replace multiple, functionally equivalent blocks with a single shared block. The delay balancing may insert one or more elements to correct for data path misalignment. The global scheduler may place portions of the program or model into conditional execution sections and create control logic that controls the model sample times or steps that the portions are enabled. A validation model, a report, or hardware description code that utilizes fewer hardware resources may be generated from a modified version of the model that is created.

Abstract: Embodiments of the disclosed subject matter can provide techniques for synchronizing data acquisition (DAQ) modules in a data acquisition system. In data acquisition systems where multiple DAQ modules are in use, it can be desirable to synchronize the DAQ modules to facilitate the analysis of signals captured by sensors coupled to those DAQ modules. This way, a signal processing platform, such as a computer, can analyze different sensor signals (e.g., an audio sensor and vibration sensor) without separately compensating for the time difference between the audio and vibration signals. In some embodiments, the synchronization techniques can include an automatic or a semi-automatic mechanism for temporally synchronizing the sensors and for arbitrating the sampling rate between the data acquisition systems.

Abstract: A system and method provides top-down programming in a graphical programming environment. A developer may utilize a component constructor to create a graphical skeleton component that represents a template for a procedure. The graphical skeleton component may include one or more hole elements that mark locations in the component at which functions may be specified. An instance of the component may be included in a graphical model, and one or more functions specified for the hole elements, thereby completing the component. The one or more functions may refer to model parameters, and bindings may be captured among the parameters. Upon execution or simulation of the model, the one or more functions specified for the component are executed, and the parameters evaluated. The functionality of the completed may depend on the one or more functions specified for the hole elements.
