How to transfer data between virtex5 and virtex7 FPGA using aurora8b10?

Jump to solution

Hi,

In my system now, there are two FPGAs need to be connected using aurora. One chip is virtex7, another is virtex5. I program the virtex7 using vivado 2016.4 and the aurora IP version is v11.0. In PG046, it says this IP is aurora 8B/10B protocol specification v2.3 compliant. However, the virtex5 needs to be programmed using ISE13.4 and the aurora IP version is v5.3. In DS637 it says this IP is aurora 8B/10B protocol specification v2.2 compliant.

Here is the question I want to make sure. Is the aurora 8B/10B protocol specification v2.3 compliant with v2.2? In my case, will there be any data errors due to the specification differences? I saw that there are four change logs related with v2.3. I don't know if these changes are related with the protocol changes.

changes on v2.3.JPG

Any advices will be appreciated. Thanks!

Hi @datangel ,

the changes only affect the flow control usage. As long as you do not use these you should be fine to connect the two.
