Hi Ricardo, It looks like the ADC mask script didn't run properly as it should only show 8 ports for ADC 0 when you only have ZDOK 0 selected. Yours seems to be in interleaved mode. I would try deleting the yellow block, replacing it with your parameters, and updating again.
Not sure, most likely you have the SX95T, otherwise I don't think the .bof file would have run. Using the even samples will give you half the bandwidth. The size of the PFB and the number of simultaneous inputs from the ADC are independent.
