Trying to build an Infiniband interface on an Virtex II Pro FPGA


I am currently trying to set up an Infiniband protocol on a Virtex 2 Pro. Therefore I use the dedicated multi gigabit transceivers (Rocket I/O s). My problem is that after finishing the link layer and testing the implementation in serial loopback mode I always get the error message from my testbench program that the synchronization gets lost. I already worked on several "standard" implementations and I often encountered false descriptions in the standard paper. Since the implementation is exactly based on the "Infiniband Architecture Specification Release 1.1" I wonder if there is already a mistake in the description? Or maybe there is another point that is not obvious I just overlooked? I would like to share my experience and knowledge with other developers who are also familiar with the Infiniband protocoll and its implementation to solve my problem. Any help is appreciated.

Regards, Quinn
