【应用手册】AN 553: Debugging Transceivers
You can use Altera® Stratix® GX, Stratix II GX, Stratix IV GX, and Arria® GX devices,
which have transceivers, to implement a number of different multi-gigabit high-speed
interfaces. This application note describes the most common causes of transceiver
interfaces failing to synchronize and some steps to debug a design’s power supplies,
resets, and PLLs, using methodical fault finding techniques. The application note
includes an example design and testbench, which you can implement on a Altera
Transceiver Signal Integrity Development Kit, Stratix II GX Edition.an553.pdf
