I closed the earlier discussion as i thought the doubt is cleared. But still I am not able to figure out some problems.
I am using offset binary now. I am giving the data vector followed by zeros and some of the results that I am getting are -
In the datasheet it is given that the BIST behaves as simple adder. So when giving this data it should have just returned the same data as result.
But in this case it looks like its just inverting the bits or XOR with 1. The two LSBs are 1 might be because of compatibility with AD9783.
Can you please verify that the output result what I am getting is correct or not ?
