Abstract: Systems and methods may highlight paths through graphical models having executable semantics. Paths through a model leading from a starting location and terminating at final source and/or destination model elements may be identified. The paths may be highlighted. A model may include hierarchical levels, and the highlighting may be extended into lower or higher hierarchical levels relative to a current level. A model may execute over a plurality of simulation time steps, and the highlighting may indicate model elements executing in a given simulation time step.

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 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 device may receive information identifying a model including information associated with elements included in the model. The device may cause the model to be executed, and may collect data associated with executing the model. The device may determine performance information based on the collected data. The performance information may be associated with the elements included in the model. The device may generate a heat map based on the performance information. The heat map may associate an element, of the elements, with a visual representation indicating performance information, associated with the element, based on a heat map scale. The heat map scale may relate the performance information, associated with the element, to performance information associated with another element. The heat map may be a graphical interface that includes a graphical representation of the element and a graphical representation of the other element. The device may provide the heat map.

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.

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 receive a model including a group of blocks, and may receive a command to execute the model. The device may assign a parameter sample time to a subset of blocks of the group of blocks. The parameter sample time may permit a block, of the subset of blocks, to be executed based on a parameter change event detected during the execution of the model. The device may cause the model to be executed after assigning the parameter sample time to the subset of blocks. The device may detect a parameter change event, associated with the model, prior to the execution of the model being completed. The parameter change event may include an event that is external to the execution of the model. The device may cause at least one block, of the subset of blocks, to be executed based on the detecting the parameter change event.

Abstract: In an illustrative embodiment, an apparatus, computer-readable media, or method may be configured to suggest determine relationships. Interaction with a block diagram model may include receiving a first portion of a block diagram model. The block diagram model may include a plurality of blocks. Each of the plurality of blocks may represent a set of dynamic equations. The interacting may be performed using the computer. Relationships between a plurality of a synthesized input, a synthesized output, a synthesized state, or a synthesized derivative, may be determined. A determination may be performed for the first portion of the block diagram model. The determining may include determining a block Jacobian pattern of relationships between two or more of an input, an output, a state, or a derivative of a first block of the plurality of blocks in the graphical model.
