After doing some digging, I am now confused about the clocks on the iBOB. Specifically, I thought the ADC clock was passed through a DCM to clean it up before use, but it looks like this is not the case. Can someone confirm? I see these lines in the system.mhs that give me this impression: PORT adc0_clk = adc0_clk
BEGIN fixedPFBspecTest PARAMETER INSTANCE = fixedPFBspecTest_XSG_core_config PARAMETER HW_VER = 1.00.a PORT clk = adc0_clk And the adc0_clk signal does not go to any of the DCMs. I have built a spectrometer that meets timing, but the output is sensitive to the sample clock speed, so I am trying to track down the problem.
