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 computer-implemented method comprising:

accessing generated code corresponding to at least a portion of a graphical model,

the accessing being performed by a processor;

graphically identifying a first graphical affordance in the graphical model,

the first graphical affordance corresponding to a first segment of the generated code, and

the graphically identifying being performed by the processor;

graphically identifying, based on graphically identifying the first graphical affordance in the graphical model, one or more portions of the graphical model,

when graphically identifying the one or more portions of the graphical model, the method includes;

receiving information associated with browsing an intermediate representation of the graphical model or the generated code; and

graphically identifying the one or more portions of the graphical model based on the received information associated with browsing the at least one of the intermediate representation of the graphical model or the generated code,

the graphically identifying the one or more portions of the graphical model being performed by the processor;

searching the graphical model for a recurring graphical affordance,

the searching being performed by the processor;

graphically identifying segments in the generated code that correspond to the recurring graphical affordance,

the graphically identifying the segments being performed by the processor;

replacing the recurring graphical affordance in the graphical model with another graphical affordance,

the replacing being performed by the processor; and

updating sections of the generated code based on the replacing,

the updating being performed by the processor.

2. The method of claim 1, where the method further comprises:

generating tracing information for associating the first graphical affordance with the first segment of the generated code.

3. The method of claim 2, where the method further comprises:

generating an independent representation that comprises the tracing information.

4. The method of claim 1, where the method further comprises:

mapping a document to the generated code using tracing information; and

graphically identifying a requirement in the document that corresponds to the first segment.

5. The method of claim 1, where the method further comprises:

updating an inferred property in the first graphical affordance; and

implementing the inferred property as a specified property.

6. The method of claim 1, where the first segment corresponds to a plurality of graphical affordances, and the method further comprises:

identifying members of the plurality of graphical affordances in the graphical model using unique graphical identifiers.

7. The method of claim 1, where the method further comprises:

searching the generated code for the first segment;

graphically identifying the first graphical affordance in the graphical model corresponding to the first segment;

replacing the first segment with another segment; and

updating the graphical model to reflect the replacing.

8. The method of claim 1, where the method further comprises:

associating undisplayed aspects of the graphical model with the first segment; and

displaying the undisplayed aspects when the first segment is specified.

9. 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;

interact with code generated based on a graphical model,

the generated code comprising at least a first segment;

graphically identify a first graphical affordance in the graphical model that corresponds to the first segment; and

graphically identify, based on graphically identifying the first graphical affordance in the graphical model, one or more portions of the graphical model,

the one or more instructions to graphically identify the one or more portions of the graphical model including;

one or more instructions to receive information associated with browsing an intermediate representation of the graphical model or the generated code; and

one or more instructions to graphically identify the one or more portions of the graphical model based on the received information associated with browsing the at least one of the intermediate representation of the graphical model or the generated code;

search the graphical model for a recurring graphical affordance;

graphically identify segments in the generated code that correspond to the recurring graphical affordance;

replace the recurring graphical affordance in the graphical model with another graphical affordance; and

update sections of the generated code based on the replacing.

10. The medium of claim 9, where the instructions further include:

one or more instructions to generate tracing information for associating the first graphical affordance with the first segment.

11. A computer-implemented method comprising:

accessing generated code corresponding to at least a portion of a graphical model,

the accessing being performed by a processor;

graphically identifying a first segment in the generated code,

the first segment corresponding to a first graphical affordance in the graphical model, and

the graphically identifying being performed by the processor; and

graphically identifying, based on graphically identifying the first segment in the generated code, one or more portions of the graphical model,

when graphically identifying the one or more portions of the graphical model, the method includes;

receiving information associated with browsing an intermediate representation of the graphical model or the generated code; and
