Abstract: A device may receive a model that includes multiple blocks. The model may include first variables that contribute to a first calculation and second variables that contribute to a second calculation. The device may determine first dependencies associated with the first variables and may determine second dependencies associated with the second variables. The device may generate a first execution function based on determining the first dependencies. The first execution function may identify first blocks that are to be executed to perform the first calculation. The device may generate a second execution function based on determining the second dependencies. The second execution function may identify second blocks that are to be executed to perform the second calculation. The device may cause the first blocks and the second blocks to be executed in a different manner based on the first execution function and the second execution function.

Abstract: A computer-based model having executable semantics may be used to simulate the behavior of a system. A substructure of interest is sliced from the model and analyzed to determine a transformation of the slice while preserving some context of the model. The transformed slice may be further manipulated outside of the model, integrated back into the model in place of the original slice, or used in other ways.

Abstract: A method, performed by a computer device, includes obtaining an in-memory representation of computer code from a block step method of an executable model in a modeling application, wherein the computer code in-memory representation includes one or more variables. The method also includes identifying, from the one or more variables, a subset of persistent variables and determining if any of the one or more variables in the subset of persistent variables are state variables. When none of the subset of persistent variables are state variables, a block output method is generated based on the computer code in-memory representation and the one or more variables. When the subset of persistent variables includes a state variable, both the block output method and a block update method are generated based on the computer code in-memory representation and the one or more variables.

Abstract: A device may obtain a model. The model, when executed, may simulate a behavior of a physical system. A user, such as, for example, an engineer, may specify a design interest for the model. The design interest may be associated with a particular behavior of a portion of the model. The device may analyze the model based on the design interest and may determine, based on analyzing the model, a group of model elements, included in the model, that are related to the design interest. The device may generate, based on the group of model elements, a model slice. When the model slice is executed, a behavior of the model slice may correspond to the particular behavior of the portion of the model. The device may analyze the particular behavior of the portion of the model based on executing the model slice.

Abstract: 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.
