LVDS error in 18.1 while using Triple Speed Ethernet IP

​Hi,

we are experiencing the same issue with the Cyclone 10GX evaluation board. If I understood correctly this seems to be a hardware bug of the evaluation board, as there is no LVDS clock connected to the bank 2L where the Ethernet Core is connected to?

The clock "C10_REFCLK1p" (n) which is used in the simple socket example uses another bank and the clock "C10_REFCLK2p" (n) is connected to pins G23 & F23, which don't support LVDS.

According to the following post, the LVDS SERDES IP requires a LVDS clock on the same bank.
