8.4. Troubleshooting Common Errors
Missing High-Speed Link Pin Connections
Check the pin connections to identify high-speed links (tx_p/n and rx_p/n) that are missing. When porting an older design to the latest version of the Intel® Quartus® Prime software, ensure that these connections exist after porting.
Ensure that the transceiver channels are not held in reset. You also need to ensure the reset port of the datapath and PMA Avalon® memory-mapped interfaces are not held in reset.
The clock inputs of the datapath and PMA Avalon® memory-mapped interfaces must be driven with a stable clock within the specific frequency range.
