AURORA 8b/10b CRC Failure

Hi,

 

I need some help with the AURORA 8b/10b core. I use VIVADO 2016.01 ,and the version of the core is 11.0(rev 4). The specification of my core is:

I can find some CRC errors in the RX end ,with some frame_errs but without hard_errs or soft_errs. I am sure the channel_up never desert during the whole time. I debug with a fixed data frame , and I can find that sometimes it lost some data with the recevied CRC value being the same with the correct one. I can also find that I recevied some more data than expected in another device with the same project.

I think the hardware maybe good because I had tested it with IBERT tools and it worked well, so I need some helps or ideas.

Thanks a lot !
