part of xc6slx45t,Aurora 8b/10b v5.3 in ISE 14.6
Implement dataflow mode of RX-only simlex in rx-board,and TX-only simplex in tx-board.
It must have only unidirectional Fiber optic connection between rx-board and tx-board,so I must use back channel of Timer
When I Power-on the two board at the same time,the RX_CHANNEL_UP of rx-board doesn't go high during initialization.
When I Power-on the rx-board first and then Power-on the tx-board,the RX_CHANNEL_UP of rx-board can go high everytime.
Is there Power-on sequence with the IP？
Can anyone give me a example design with back channel of timer of the IP?

Perhaps your Aurora Simplex-TX might already send out all training-sequence data (Sync & Polarity codes).
( If you power-up your RX after you TX is powered-up, or at the same time)
Suggest you to power-up your RX first for a workaround.
If your system needs TX to be power-up first, then you have to modify the TX timers parameter (C_ALIGNED_TIMER) to the max value, so your TX is still sending Sync & Polarity codes after your RX is powered-up.
