Hi,
I am having one more problem. I was using the fmc 150 module with ml605 board with the reference design given from Avnet. I connected the DAC outputs directly to the ADC inputs for checking. I observed that when I include a microblaze processor based embedded system, the DAC outputs are getting severely distorted and not following the input properly. However, when I download the same design removing the embedded system component, the DAC outputs become normal again. There is no common signal between the fmc 150 ADC-DAC module and the microblaze processor based embedded component. The only common component is that I used a 200 Mhz clock derived using a mmcm block (the same mmcm block outputs also drive part of the fmc 150 adc-dac system) to drive the microblaze system.
Any idea on why this is happening? Is there any commonly known remedy?
