Hi, i'm new in xilinx and i'm using IP catalog, FIR compiler for evaluating if my filter has the corrent impulse response.
After synthetizing out of module my filter i start behaviour simulation putting on top the tb file.
The simulation start, and i should see at least a signal rising as the absolute value of the CoefData but i cannot see anything on output of the impulse response.
This is the coe file:
Radix = 10;
Coefficient_Width = 16;
CoefData = 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,-16,-16,-16,-16,-16,-32-16,-112,-176,1776,-12800,32448,-12800,1776,-176,-112,-16,-32,-16,-16,-16,-16,-16,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0;
My band pass filter should have a f0=250 MHz and cut from -4dB to 12 dB on resonance.
What i'm messing?

Can you please let me know if you have run the simulation till the end. If yes, can you please let me know the Vivado version that you are using.

MY vivado version is 2016.1.
I changed the simulation time to 50 us and the frequency sampling to 25 MHz, and now is fine. (i can see the coefficients)
What should i do to simulate the frequency response to impulse or a AWGN noise in in the IP catalog (I cannot use System generator).
