S-Function with Separate C Code and VHDL generation

I'm attempting to generate an s-function block that can generate (and connect to other components) VHDL code or C code depending on its placement and how I select components for code generation. It looks like this is possible with C but I am having trouble finding resources for VHDL generation. Any help would be greatly appreciated.

I don't think HDL code generation is supported for S-functions, but you might be able to get around it by wrapping the S-function with a subsystem that is defined as a Black Box Implementation.

Kaustubha, that's exactly what I'm looking for. To expand upon this, is it possible to associate code with the same block?

Do you mean that you have your own HDL implementation for the block? If yes, I believe that's exactly what the Black Box implementation let's you do - associate your own HDL implementation with a subsystem.
