Max10: 10M16DAF256I7G ADC not working

Question

Hi

I'm having trouble with on chip ADC from Max10 10M16DAF256IG7. I create an "adc control only" using Qsys (PLL included) and monitor the signals using Signaltap. However I do not get any "adc_response_valid" on Signaltap. I tried a very similar code with DECA evaluation board (10M50DAF484C6) and it works fine. I understand that DECA evaluation board has Dual ADCs, while the 10M16DAF256 has only a single ADC. I did modify the ADC module in Qsys to fit the 10M16DAF256, but it does not work.

Attach is my project design.

Some helps on this problem please.

Thanks

I think the ADC on 10M16 should be similar to the one on 10M08.

And here is the TRM for the ADC design

Here is an example for using ADC on 10M08
