We have a design that utilizes the daq2_zc706 project. We've integrated a core that continuously outputs known data to the DAC module. This works great when the board is freshly booted, but after running for an extended period of time, the output goes away. I've verified with a ILA core that our core is still outputting the data. After a reset the output is again generated properly, but again goes away after some time.
I've probed the green path in the block diagram and verified the data is still being generated by the sync_dac block. Any insight into what might be happening/how to debug would be appreciated.
