| You cannot select dac1 by itself. You can send data from the host to just dac0 or you can send data to both dac0 and dac1. |

DAC problem is solved as i found out that in order to use DAC1, I have to enable both DACs , i.e: DAC0 and DAC1 in Arb example. Now I am looking for the working FIR model. Please update me when you will finish the updated version as its too urgent for me. Thanks.
Regards,

I have seen the ver1.07. After downloading the bit stream for FIR, the filter is working fine and control register also but still i could not see the filtered output at DAC0. I even increased the amplitude at ADC. Have you tested this bit stream for your board? My board has AC coupled DAC. I just want to confirm whether i need to do some other setting for AC coupled?
Regards,

| I gave it a 2Vp-p signal at the input of adc0 and I got a 500 mVp-p signal on the output of dac0. I would make sure you are using the stream application and have adc0 and dac0 enabled before you start streaming. |
