I want to see the digitalized output with sine wave analog input using xadc wizard. But I am not obtaining sine wave output instead I get a constant output. I have attached the image of the simulation output. The design.txt file is the analog stimulus file stored as example file in xadc.
xtest_tb:

reg reset_in;

x_test DUT (
.di_in(16'b0), // input wire [15 : 0] di_in
