In an embodiment, a model is sliced into a plurality of slices. A slice in the plurality of slices is selected. A portion of code, that corresponds to the selected slice, is identified from code generated from the model. The identified code is verified to be equivalent to the selected slice. Equivalence may include equivalent functionality, equivalent data types, equivalent performance, and or other forms of equivalence between the selected slice and the identified generated code.

Verification of computer-executable code generated from a model

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.

A method may include storing bug reports in a memory, where a particular one of the bug reports describes a software bug and includes information about a modeling application. The method may further include receiving, from another computer device, a request for bug reports relevant to a model generated using the modeling application, where the request includes information about the model; identifying one or more relevant bug reports, in the stored bug reports, by comparing the information about the modeling application, included in the stored bug reports, with the information about the model, included in the received request; and providing information about the one or more relevant bug reports to the other computer device.

Bug report checks in a modeling system

In an embodiment, a model is sliced into a plurality of slices. A slice in the plurality of slices is selected. A portion of code, that corresponds to the selected slice, is identified from code generated from the model. The identified code is verified to be equivalent to the selected slice. Equivalence may include equivalent functionality, equivalent data types, equivalent performance, and/or other forms of equivalence between the selected slice and the identified generated code.

Coverage data may be collected for a model. The coverage data may include model coverage data and code coverage data for test cases input to the model. The coverage data may be presented to a user as data indicating a correspondence between coverage outcomes for the model and coverage outcomes for the code used to implement the model.
