Abstract: A system determines what aspects of input sources contribute to code generation and provides associations between the input sources and components of features of the generated code. These associations may be visualized by displaying visual cues of the associations. The input sources may be of different types, including but not limited to a model, a code generator and values for atomic configuration setting for code generation. The visual cue that is displayed may take the form of a visible connection between the input sources and the relative portion or portions of the generated programming code. Suggestions may be generated in response to edits to the generated programming code as to how the sources may be modified to provide desired changes in the generated programming code. Analysis may be performed to identify artifacts in the generated programming code and associations to the sources may be identified to specify what source contributed to portions of the generated programming code.

Abstract: In an embodiment, a modeling component generated in a first modeling environment can be implemented in a second modeling environment. The modeling component is executed in the first modeling environment. A first behavior of the modeling component in the first modeling environment is obtained based on the executing.

Abstract: The present application is generally directed to mediums, methods, and systems for identifying and manipulating active code components. In exemplary embodiments, a user control interface is provided for displaying a source design which includes instructions in a preprocessor language and instructions in a source language. A resolvable preprocessor condition may be identified along with an instruction in the source language that is associated with the resolvable condition. The resolvable condition and the associated condition may be displayed, and the associated condition may be graphically indicated as controllable by the resolvable condition. A user may supply an input that provides a value for the resolvable condition. In some embodiments, instructions in the source language are displayed and, upon selection of one or more source language instructions by a user, a preprocessor condition that is associated with the selected source language instructions may be displayed.

Abstract: Exemplary embodiments employ a mapping among entities that are related to each other. The entities may include a graphical model, generated code, a generated report, a requirements document and/or an intermediate representation. The mapping may facilitate graphical identifications between parts of one entity that maps to part of another entity. The graphical identification may occur based on a selection of a part in one of the entities.

Abstract: A code verification tool verifies that code generated from a model represents all of the functionality of the model and does not contain any unintended functionality. The code verification tool may receive for examination a model or an intermediate representation (IR) of the model and the generated code or an intermediate representation of the generated code. The code verification tool may create further intermediate representations of the model and/or the generated code in order to compare the functionality presented in both.

The device identifies an order for the code generation optimizations based on the determined information, generates optimal code for the model based on the identified order for the code generation optimizations, and outputs and/or store the optimal code.

Abstract: A device receives a model that includes blocks and lines provided between the blocks, and identifies first candidate boundaries for the model. Each of the first candidate boundaries defines a group of blocks. The device generates an intermediate representation (IR) of the model, performs an optimization of the IR to generate an optimized IR, and identifies second candidate boundaries for the model based on the optimized IR. Each of the second candidate boundaries defines a group of blocks, and the first and second candidate boundaries define a set of candidate boundaries. The device reduces the set of candidate boundaries, to a reduced set of boundaries, based on code efficiency metrics or metrics associated with a hardware platform. The device generates code for the model based on the reduced set of boundaries, and outputs the code.
