Aurora faster than 6.6Gbps on Kintex 7 484 package -2

Jump to solution

I'm working on a design that is targeting 10Gbps for a Aurora transciever.  Reading through datasheets I've found that the following parts (and a few others) should support this speed:

  • xc7k70tfbg484-2
  • xc7k160tfbg484-2
  • xc7k160tffg676-2

However, when I try to configure the 'Aurora 64B66B' ip core in Vivado 2018.2 it only allows me to configure the line rate up to 6.6Gbps on the fbg484 package parts.  The limit is 10.3125Gbps when I am targeting the ffg676 part.

Can anyone confirm that the fbg484 packages are capable of this?  It appears to just be a software bug because most of the fbg packages are limited to 6.6Gbps .

Hi @dlarsen,

 

This is a software bug, and will be fixed in aurora 64b66b V12.0(Vivado 2019.1).

 

Thanks
