how to convert Simulink model to VHDL, ,Matlab function using VHDL

[Altera_Forum]

Hope all is well, i am just wondering if any one has ever converted simulink model to VHDL codes, or has ever been able to write a matlab function using VHDL rather than c or c++

Tools like DSPBuilder(Altera) or sysgen(Xilinx) hdl coder(Mathworks) do the conversion and not anybody can do that. 

Writing hdl for matlab function is not supported by matlab.

using HDL coder you can write M code in a similar style to HDL - but then why not just write the HDL? 

 Converting simulink models to HDL is non trivial because only a subset of the simulink blocks are supported for code generation, and you will have compilation and timing problems if you do not create the simulink models in the correct way.
