1G/10GbE IP works on 1G/10G mode with auto-negotiation turned off

Hi Chee, Thanks so much for your kindly reply. 1. Just would like to check with you on the specific Quartus version that you are using? A: I will check with customer later. 2. I understand that you have two duplex PHY IP instances with one PHY A TX sending data to PHY B RX. Would you mind to try using one duplex PHY IP and then perform a fiber loop from TX back to its own RX to see if similar issue occurs? This would help to facilitate and ease further debugging. A: one duplex PHY with fiber loop back can receive correctly after unplug and plug back the fiber. 3. As I understand it, the register 0x400 has value of 0x8. The link is operating at 1G without AN. Just wonder if you have had a chance to monitor register 0x400 before cable unplug, after cable unplug and after cable replug to see if there is any difference. A: sure, will do the experiment later. 4. I understand that you mentioned triggering reset does not recover the PHY. Would you mind to further elaborate which specific reset are you referring to? Just wonder if you are triggering reset to the PHY IP as well as the XCVR reset controller? A: I meant the altera transceiver PHY reset controller IP, with default preset(rx_analogreset duration 70000ns, rx_digitalreset duration 4000ns ) 5. Would you mind to help tapping status signals ie rx_is_lockedtodata, tx_cal_busy and rx_cal_busy to check on the CDR and calibration? A: check the LTD and LTR. The CSR address 0X464H is all FFs. 6. Mind sharing me with the .ip file of you PHY so that I can have better understanding of your configuration. A: I will check with customer. Regards， Nicole

Hi Chee Sorry I made a mistake, the PHY IP is 1G/10GbE and 10Gbase-KR phy on A10GX. But other describtion are correct. Q17.1.2Pro. The PHY file is as attached. Regards， Nicole
