Hi FPGA Reference Designs Support Community,
I just did some experiment so that I can verify data receive from ADC should same data sending from DAC. I run No-OS platform AD-FMCOMMS1 and perform debug thru Chipscope tool on AD9643(adc_mon_data) and AD9122 (dac_dbg_data) from the same signal test (dac_dma_setup(fmcSel);) concurrently .
My initial expectation is the data I receive from ADC (receive) must be same data from DAC (transmit). But from data debug by Chipscope on ADC shows different content. I also use signal from dds_setup(fmcSel, 1000000, 1000000); and its behave similar result.
Do you have any idea or theory explanation? Then how can I get 100% data integrity on this system?
