PMA_INIT does not reset the transceiver

I have a simplex, single lane Aurora 64b66b link between two FPGA. It works as expected (link up, data transferred...), but I cannot reset the TX side. I want to power down the transmitters, but I cant.

I placed an IBERT on the receiver side, which can still scan a valid eye after I asserted pma_init, reset_pb, and core_control's power_down, on the transmitter.

I use:

  • Vivado 2017.4 (Win 10)
  • xc7z030sbg485 (Znyq)
  • Aurora 64b66b (11.2)
  • TX-only Simplex, single lane, 2Gbps

Hi @betontalpfa ,

I think you can power down by setting power_down signal to '1'.

Thanks,
Rahul Khatri
