How to use Matlab generated c code for High Level Synthesis ?

I wrote an algorithm for Fast Fourier Transform (FFT),then generated executable

c code for it. The settings done by me are :

1) Generate all Functions into single file.

2) included main.c - in Custom code \Additional source files .

Now I want to use that generated c code for High level synthesis using GAUT 2.4.3 build 17/02/2010 tool. when I try to compile the source file in GAUT it is showing some errors. Help me please.

Hi Shravan,

I believe you are generating C code from MATLAB code using MATLAB Coder and trying it to take it through GAUT - High-Level Synthesis tool. I am not sure about the subset of language syntax and guidelines one has to follow to take C code through GAUT HLS tool. Please refer to documentation for GAUT for such questions.

Please note MathWorks recommended workflow for this is to generate HDL directly from MATLAB or Simulink using HDLCoder.

You can learn more about successful ASIC/FPGA development user stories with this workflow.

Thanks

There are functions such as mpcActiveSetSolver() that MATLAB HDL coder does not support. This function, allows C code generation with MATLAB coder btw. What would be the solution for this case if not using MATLAB coder and then Vivado HLS for instance?

If you're using a synthesis tool, don't you need HDL code, and not C code? You probably should be using HDL Coder instead.

Thank you for that, but Matlab is not supporting HDL Code generation for 2-D arrays, which are there in my function. I would like to get RTL from C code directly .

[Kaustubha Govind]

I don't know anything about GAUT, but it is possible that it doesn't support C code for synthesis, which is why you see the errors.

[Shravankumar P]

Then can I use the c or cpp code in Vivado HLS for RTL generation.Please I need to be solved ,help me.

[Kaustubha Govind]

Shravankumar: Sorry, this is not really a domain that I am familiar with. You want to try other forums that specialize in that domain.

Anyway You tried to help me .Thank you
