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 Andre, I checked the KDB link and I can see below are 2 other factors that may affect TSE auto-negotiation. Feel free to check it out. https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/solutions/rd09082010_546.html https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/solutions/rd02282012_17.html General recommendation is to always try out latest Quartus version as there will be more issue fixed update in latest Quartus version. Thanks. Regards, dlim

    Dear Dlim,

    thanks for your reply, that was much faster than I expected !

    I have carefully read the articles, for the first KDB answer I can assure that AUTONEG is enabled on

    both sides - the PCS and the switch, so this is not causing the issue.

    Regarding the second KDB answer ( incorrect device availability advertized ) I'm not sure if this has

    been fixed in the current quartus version. The KDB article is dated from 2012 - I have compiled my

    design with Quartus 16.0 and also tried 16.1 both without fixing the problem. Is there something

    like a list of release notes where I can see which issues have been fixed and which are still open ?

    All the best!

    Andre
