Adding output signals to DSP Builder exp conduit

I currently have a single bool input and a single bool output.

When I add a new output in Simulink and rebuild, it doesn't show inside Qsys (I've tried bool and uint(32)). The system is updating (If I remove the existing output it no longer shows in Qsys).

Is there an additional step or setting to control the input and output signals? :confused:

...I have build a simple simulink model using MegaCore FFT bolck. I gave the following inputs to the fft megacore block.

Code:

reset_n : 1
inverse : 0
sink_valid : 1
sink_sop : counter counts 0 to 127, if count ==0 then sink_sop =1
sink_eop : counter counts 0 to 127, if count ==127 then sink_eop =1
sink_real : unsigned 8 bit value
sink_imag : unsigned 8 bit value (0)
sink_error : 2 bit (00) no error
source_ready : 1

unfortunately no output.....:cry: What is the mistake I have done?

here is the simulink model.

Waveform input according to the above mentioned order

Simulink mdl file also attached with the post.
