I have developed a controller for a digital control problem. I want to implement the controller obtained, which is a digital transfer function, on an FPGA. I tried 'import from work space' in the fdatool, but I get the error "HDL generation for the filter structure xxx is not supported"
Could someone please explain the procedure to be followed to get the HDL code of one's custom filter? there seem to be many tutorials to get the HDL code of filters designed using FDATOOL

Have you considered realizemdl function to generate a Simulink and using HDL Coder to generate code from the Simulink model?
realizemdl
Simulink subsystem block for filter
https://www.mathworks.com/help/dsp/ref/dsp.allpassfilter.realizemdl.html
d = fdesign.lowpass('N,F3dB',4,0.25);
filterobject = design(d,'butter',Systemobject=true)
new_system('LPFilter');
realizemdl(filterobject);
