I am trying to deserialize data from an ADC (FMC116 - 125MHz) using the Xapp524 application note.
At this time the only timing constraint applied is
NET "*BitClk_MonClkOut" TNM_NET = DCO2;TIMESPEC TS_DCO2 = PERIOD "DCO2" 500 MHz HIGH 50%;
NET "*BitClk_MonClkOut" TNM_NET = DCO3;TIMESPEC TS_DCO3 = PERIOD "DCO2" 500 MHz HIGH 50%;
For the two high speed clocks of the two 4 channels ADCs out of the four provided in FMC116.
While I am getting correct data from the 1st ADC the 2nd sometimes gives me instead of pattern "0011100011100011" the value "1100111000111000".
Do you have any recommendations about additional constraints that may i would have to use?
