I set the subsystem to "Treat as Atomic Unit", the function name option is "User Specified --- Pid_Control", and saved it as a library.
the reuseable subsystem
But when I call the function using Simulink,Embedded Coder generates multiple functions (with different function names but the same function content) instead of reusing the function.
And strangely, sometimes it can be reused successfully. I checked the input signal types of these functions and they are all the same.
What could be the reason? thanks
same function with different code

Hi @chen lan,
I understand that Embedded Coder generating multiple functions instead of reusing a single function for your reusable subsystem.
It can occur due to following reasons:
  • If there are any differences in datatypes, dimensions, or min/max values of signals driving the subsystem inputs.
  • Even minor differences in subsystem settings or connected signals can prevent reuse.
  • If signals are read at different phases of the simulation (e.g., initialization vs. execution), reuse may not occur.
You can follow these steps to resolve the Issue:
Additionally, you may refer this link for detailed guidance on generating reusable code from library subsystems:
