Hi,
It sounds like you are experiencing some issues with the AXI4-Stream IIO Read block in your implementation. Without more specific details, it is difficult to pinpoint the exact cause of the problem, but here are a few general suggestions that may help:
- Check the AXI4-Stream IIO Read block configuration: Make sure that the block is configured correctly, including the sample size, number of channels, and data type. Verify that the data being read from the ADC matches the configuration of the block.
- Check the FIFO configuration: Since you mentioned that the frame size of the HDL FIFO block is several hundred, make sure that the FIFO block is configured properly to accommodate this size. Ensure that the FIFO depth is large enough to hold the data.
- Check the clocking and synchronization: Make sure that the clocking and synchronization between the ADC and the AXI4-Stream IIO Read block are correct. Verify that the clocking of the ADC is properly synchronized with the AXI4-Stream interface clock.
- Check for potential issues with data size: It's possible that the data size is too large for the AXI4-Stream IIO Read block to handle properly. You may need to reduce the data size or consider using multiple AXI4-Stream IIO Read blocks in parallel to handle the data.
- Check for intermittent issues: Since you mentioned that the issue is intermittent, it's possible that there are occasional communication issues between the ADC and the AXI4-Stream IIO Read block. Try to identify any patterns or specific conditions when the issue occurs.
If these suggestions do not resolve the issue, it may be helpful to provide more specific details about your implementation, such as block diagram and configuration settings. This can help to identify potential issues or provide more targeted solutions.
