Aurora 64B66B reset2fg goes active once a while

My generated 4-lane Aurora 64b66b simplex TX output "reset2fg" sometimes goes active. During that time TREADY also goes low (not accepting transmitting data) and cause my transmitted data to overflown. The Aurora user guide does not describe much about the signal reset2fg beside saying it is used to reset the frame generator in the example design.

My question is why the reset2fg goes active and TREADY drop. What is the cause and how to fix it.

I notice that all 4 lanes stay up, channel is still up, mmcm does not go out of lock at all.

Thanks,

Tri Doan
