ZED Board VIA Position (Bottom side)

I want to check the via position on bottom side of PCB with the pin number below.
J20,J21,J22, K21, M19,M20, N22, P20, P21, P22
 
I used FMC Connector for LVDS. 
But it is presumed that the signal distortion occurs and I want to apply the terminal resistance.
I would like to attach a resistor to the copper foil(via) but it is too hard to verify its position.

Hello Asher,

Hello Asher,

I agree, it is quite difficult to determine what via corresponds to what FMC Pin. One solution I can offer is that the source files are available to you. To obtain them you must contact your Local Avnet FAE and have them request them for you. Using those you could determine which via corresponds to what. My other sugggesitong would be to ask for assistance over at this Digilent forum.

Thanks,

Josh

Hi Josh,

Hi Josh,
AVNET in Korea says it can not support this problem.
Do you have any other way?

I solved this problem. 

I solved this problem. 
But I received an answer from the distributor that DIGILENT can not support the PCB Project.
So, I used PDF gerbers with laser printer.
