why does the analog sim file make no scene on A-7 XADC IP-core

I use the VAUXP and VAUXN as input ports to generate a simulation.The code is as the example in UG480, the design.txt I refer to the PG091.

However it doesn't work, the wave of input is X.

Do you have any advice?

from the description, it could be anything...

 

obviosu things thta we have all done, worht checking

a) have you run the simulation long enough for the adc to initalise ( search the forums , it can be a "long" time )

b) If in ISE, its easy to simulate th eworng level of the desing, and end up with no clocks.

 

As say, with out more information , very hard to do more than speculate in the glass ball..
