Use case:

Send out bus containing signals whose properties (name, data type, default value) are derived from a database.

What is a better approach? Create signal objects for each signal, or a bus object parametrized with rename/override capability?

Maybe an image will assist!

Yes, currently I have a matlab code that generates bus objects that I assign to the blue bus creator. I keep the override bus signal names option unchecked so as to use the generated signal names.

My primary question is - what is the difference, if I no longer generate and assign the bus object, but generate and assign signal objects to 'a' and 'b' in this picture? The data types, names and properties of the signal objects, or the bus object, won't change once generated, but the signals may have different data types.

My purpose currently doesn't include code gen, but it might in the future so design for codegen is desirable.

'Is the question about whether the generated code would be more efficient if you used a bus, compared to if you used a whole bunch of signal objects?' That wasn't my question, but now that you mention it, I'm interested to know! My impression or guess would be that it doesn't make a difference as long as bus is not 'non-virtual' but I'm not an expert.
