Functions reuse in generated code

I have a Simulink 2014a model that contains two identical subsystems from a user-defined library. For these subsystems, function packaging parameter is set to reusable. One of the subsystems inputs are fed by constant block, while the other subsystem inputs are fed by gain blocks. In the generated code (using embedded coder), the functions generated for the two subsystems aren't being reused. When comparing subsystem checksum, I noticed that "ReadsInputInStartFcn" identifier is different between the two subsystems. Note that, I am using a "MATLAB Function (fcn)" block in both subsystems. Could you please explain the root cause of this difference?

I still need to see what is written inside each MATLAB Function block for two subsystems respectively.

R2017a can open models created in R2014a, so if you could attach your model and associated .m files then we could explore them. Birdman would just have difficulty opening the files if they had happened to have been created with R2017b.

I have the same problem. I have got around this problem by inserting a Signal Conversion block in between the Constant block and the atomic block. I have checked that it does not introduce any additional code, and this way, EC seems to understand that the two blocks are effectively the same and generates a single C function.
