Hardware issues can range from link bring-up to problems seen after hours of testing. This section provides debug steps for common issues. The Vivado debug feature is a valuable resource to use in hardware debug. The signal names mentioned in the following individual sections can be probed using the debug feature for debugging the specific problems.
Many of these common issues can also be applied to debugging design simulations. Details are provided on:
•Problems with the MDIO
•Problems with data reception or transmission
•Problems with High bit error rates
