Hello, is there an know problem with the 1000Base-X autonegotiation in the PCS_PMA unit of the triple speed ethernet mac ? Best regards, Andre

The design is compiled with Quartus 16.0 for CYCLONE V SOC with transceivers I follow the PCS initialization scheme suggested in the TSE user manual and have already tried the workaround suggested...

Hi Dlim,

meanwhile I have also compliled the design with QUARTUS 18.1 i.e. the latest prime version that is

available ( the lite edition ). I have checked the version register of the PCS core and found that it has

been changed from 0x1000 to 0x1201 so the IP core is a newer version however the autoneg does

not work either. Only thing that makes the 1000Base-X link work properly is disabling the autoneg

on both sides ( i.e. PCS and switch ) of the connection.

Best regards,

Andre
