Consider an unconditional top level subsystem of a model. 'Initial output' field of Outports in top level is disabled in block parameter dialog. Does this field affect the code generation. If yes how it will affect?
I am using matlab r2007a with embedded coder. I have seen if Initial output has some value and even if it is disabled, associated signal in generated code is initialized with that value in mdl_initialize function.

There is an optimization option which you can check to remove the zero initialization of root level I/O ports: "Remove root level I/O zero initialization". See the doc here. Be aware that this only counts for initial values of zeros or when the option is disabled.

This does sound like a bug. There shouldn't be an initialization when the option is disabled. I wasn't able to reproduce this in newer versions though. Please try with a newer version than R2007a to see if the issue persists.
