How to achieve data transmit between Vertex7 FPGA and ultrascale FPGA with GTH?

[ly-309]

I want to use GTH to realize data transmission between Vertex7 FPGA and  kintex ultrascale FPGA.I have used Aurora 8b10b IP to realize. But,Sometimes I find that the soft_err is asserted，then the lane_up is deasserted . I want to know that if the GTH can be used directly between Vertex7 FPGA and ultrascale FPGA . If  do  I need  to set  the Aurora 8b10b IP core specially? Thanks very much。

hi @ly-309 

what is the TXDIFFCTRL settings on both Aurora?

did you test with IBERT?

Thanks,
