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.

Claims

1. A computing system comprising:

one or more devices to;

identify generated code, the generated code;

corresponding to at least part of a graphical model, and

comprising one or more segments;

bi-directionally map, in an integrated environment, content related to the graphical model to the one or more segments in the generated code,

the bi-directional mapping providing for an identification of at least one of;

the content mapped to the one or more segments, or the one or more segments mapped to the content;

provide, based on the bi-directional mapping, tracing information; and

receive, based on the tracing information, debugging information indicating that at least one of the one or more segments is debugged,

the debugging information including an identification of one or more graphical affordances in the graphical model that correspond to the at least one of the one or more segments that is debugged.

2. The system of claim 1, where the one or more devices are further to:

use the integrated environment to facilitate simultaneous viewing of the graphical model and the generated code.

3. The system of claim 1, where the tracing information associates the content with the one or more segments.

4. The system of claim 3, where the one or more devices are further to:

use the integrated environment to generate a deployable representation for code inspection,

the deployable representation including at least one of;

the graphical model,

the generated code, or

the tracing information.

5. The system of claim 4, where the deployable representation is used for code inspection external to the integrated environment.

6. The system of claim 1, where the one or more devices are further to:

use the integrated environment to generate an independent representation comprising the tracing information.

7. The system of claim 6, where the one or more devices are further to:

use a programmable application program interface (API) to programmatically identify at least one of the one or more segments or the content based on the independent representation.

8. The system of claim 1, where the one or more devices are further to:

use a programmable application program interface (API) to allow a user to apply an external code debugger to the generated code.

9. The system of claim 1, where the one or more devices are further to:

use a programmable application program interface (API) to allow a user to apply an external code browser to the generated code.

10. The system of claim 1, where the one or more devices are further to:

use a programmable application program interface (API) to synchronize a graphical model debugger with an external code debugger to debug the graphical model and the generated code.

11. The system of claim 10, where the graphical model and the generated code are debugged simultaneously.

12. The system of claim 1, where the one or more devices are further to:

use a programmable application program interface (API) to map a document to at least one of the generated code or the graphical model using the tracing information,

the document comprising a requirement that corresponds to the one or more segments and the content, and

at least one of the content or the one or more segments being graphically identified when the requirement is selected.

13. The system of claim 1, where the one or more devices are further to:

use the integrated environment to allow a user to modify the one or more segments to update the content related to the graphical model.

14. The system of claim 13, where the one or more devices are further to:

use the integrated environment to allow a user to specify a property that cannot be modified, the specifying prohibiting the property from being modified.

15. The system of claim 1, where the one or more devices are further to:

use the integrated environment to facilitate simultaneous viewing with respect to the graphical model and the generated code.

16. The system of claim 1, where the one or more devices are further to:

use the integrated environment to associate an undisplayed aspect of the graphical model with the one or more segments and

use the integrated environment to provide, for display, the undisplayed aspect of the graphical model when the one or more segments of the code are selected.

17. A method comprising:

identifying generated code,

the generated code corresponding to at least part of a graphical model,

the generated code comprising one or more segments, and

the generating being performed by a processor; and

bi-directionally mapping, in an integrated environment, content related to the graphical model to the one or more segments,

the bi-directional mapping providing for an identification of at least one of;

the content mapped to the one or more segments, or

the one or more segments mapped to the content,

the bi-directional mapping being performed by the processor;

providing, based on the bi-directional mapping, tracing information,

the providing being performed by the processor; and

receiving, based on the tracing information, debugging information indicating that at least one of the one or more segments is debugged,

21. The method of claim 17, further comprising:

associating an undisplayed aspect of the graphical model with the one or more segments; and

22. A non-transitory computer-readable medium storing instructions, the instructions comprising:

one or more instructions, which when executed by a processor, cause the processor to;

identify generated code,
