I want multiple sfun blocks to use a common C file in Simulink, but I get an error. Is this kind of usage possible ?

Hi Talha,
The issue you are facing likely arises from shared static or global memory, which can cause conflicts when multiple S-function instances are used in the same model.
To resolve this, you can use "DWork" vectors. "DWork" vectors allow each instance of an S-function to have its own separate memory block. This prevents data from one instance from overwriting data in another, thereby avoiding simulation errors or incorrect results.
You may read more about the "DWork" vectors here:
I hope it helps!
