1. A device comprising: one or more processors to: receive code in a modeling environment format, receive a model in the modeling environment format, receive relationships information associated with one or more relationships between the code and the model, combine the code, the model, and the relationships information to generate an output file in a non-modeling environment format, the output file, in the non-modeling environment format, identifying the one or more relationships between the code and the model, and output or store the output file, when outputting the output file, the one or more processors are to: provide the code, in the non-modeling environment format, for display with the model in the non-modeling environment format, selection of a portion of the code, in the non-modeling environment format, causing a portion of the model, in the non-modeling environment format, to be identified, and selection of the portion of the model, in the non-modeling environment format, causing the portion of the code, in the non-modeling environment format, to be identified, the portion of the model, in the non-modeling environment format, corresponding to the portion of the code in the non-modeling environment format.
