Rx block lock in E-Tile Hard IP for Ethernet

Hi, I am doing simulation using E-Tile Hard IP for Ethernet with 25G x 4channels . Tx serial lines are looped back to Rx. Rx_block_lock signal is getting asserted for the first time reset is re...

Below is what I observed in the simulation:


After asserted tx/rx rstn again, the IP will take some time to block lock, and then asserted the *_ready signals.

During this period, the signal may not stable, and the local_fault signal can be asserted. However, after the *_ready signals are asserted, the local_fault signal will stay low.


This is NOT expected if the local_fault signal always stays high after de-asserted the tx/rx rstn.
