I am using HDL coder for HDL code generation,i have made simulink model and i have used System objects,and Matlab function block in model,while converting into hdl coder using hdl workflow advisor ,there is an error is that system blocks and matlab function block,containing system objects are not supported for hdl code generation,when the block input have non-descrete sample time,in RTL code & Testbench option

I have developed FFT using MATLAB function block,Simulink block and system object. exact error is.... "system blocks and matlab function block,containing system objects are not supported for hdl code generation,when the block input have non-discrete(constant or inf) sample time"

Please put a snapshot of the model here, so we can look at it.

I suspect that you need to put in a Sample and Hold block in front of all the inputs.

If you are looking for MATLAB coding style for generating HDL using HDL Coder you can find some samples here.
