Demo Program THDB - ADA HSMC Board

Hey Guys, I'm using an Altera De2-115 Board and a THDB-ADA Hsmc Board. I just tried out the dmeo program, but it seems that it won't work right.

I connected the oscilloscope and I get two added sinus waves(at least I think that). But on the Clock I don't get a good signal so I suppose that also the signal on DA-Channel B is not correct.

i tried do understand the demo program but I'm not a fpga, verilog and so on pro so sorry. Maybe someone could help me or had a pic how the demo program should look like.

BTW: The ada utility program works fine!

Thanks!

    could you posta picture of the output wave? I don't know anyti g about the chip, but it could be overshoot. Does the frequency and voltage change anything in the signal's shape?

    sure, I attached two pics. The screenshoot from the osci after i run the demo program waveform generator and the second

    is the logic analyzer after I did all the steps for the a/d and d/a converter(connect A and B for example etc.)
