If data is not being transmitted or received, check the following conditions:

1. If transmit <interface_name>_tready is stuck Low following the <interface_name>_tvalid input being asserted, the core cannot send data.
2. If the receive <interface_name>_tvalid is stuck Low, the core is not receiving data.
3. Check that the aclk inputs are connected and toggling.
4. Check that the AXI4-Stream waveforms are being followed.
