LogiCORE IP XAUI v10.1/v10.2 - sync_status is deasserted during data transfer on Kintex-7 and Virtex-7 Initial or General ES devices

描述

During data transfer on Kintex-7 or Virtex-7 Initial ES or General ES devices,sync_status is de-asserted. I do not see rxnotintable or rxdisperr being asserted.

解决方案

To work around this issue, make thefollowing changesin the*_block.vhd (v) file:

Verilog:

From:
mgt_rxlock_r1 <= mgt_rxlock and (not mgt_rxelecidle_i) ;
To:
mgt_rxlock_r1 <= {4{mgt_plllocked}};

VHDL:

From:
mgt_rxlock_r1 <= mgt_rxlock and (not mgt_rxelecidle_i) ;
To:
mgt_rxlock_r1 <= (mgt_plllocked & mgt_plllocked & mgt_plllocked & mgt_plllocked);
