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

Hi Andre, There is too many design changes from one Quartus version to another Quartus version. The Quartus release note doc won't be able to track all the low lower design fix detail. Regarding the KDB fix update - Unfortunately this was old 2012 KDB case where the original issue database was already obsolete in Intel and therefore there is no way to track back the exact version that contains the fix. Therefore, I can only recommend to you to upgrade to latest Quartus version like v19.1 or v19.2 if possible. Another thing to check with you is have you completely isolate this is due to auto-negotiation feature issue where there is no concern from board design signal integrity or cable issue ? Eg : like did you disable auto-nego feature and fix the Ethernet speed and everything is working fine ? Eg : or at minimum ensure Ethernet traffic flow is working with TSE internal loopback enable ? Other debug suggestion will be to cross check your design with TSE IP reference design in below link https://fpgacloud.intel.com/devstore/platform/14.0.0/Standard/triple-speed-ethernet/ Thanks.
