If data is not being transmitted or received, check the following conditions:
- If transmit
<interface_name>_treadyis stuck Low following the
<interface_name>_tvalidinput being asserted, the core cannot send data.
- If the receive
<interface_name>_tvalidis stuck Low, the core is not receiving data.
- Check that the
aclkinputs are connected and toggling.
- Check that the AXI4-Stream waveforms are being followed.
- Check core configuration.
