Altera LVDS SERDES for Arria 10 Soc Kit

Hi everybody !

I use Arria 10 Soc Devkit.

I want to transfer data from Arria 10 via SFP+ to another FPGA kit. For test, i try to transfer data via SFP+ and loopback through fiber cable, with data rate 1.25Gbps.

I use Altera LVDS Serdes IP core to perform this task. But when I compile I get errors in the Fitter. Cannot place pin "sfpa_tx_p" .

Please help me how to handle this error !

This is my error image and design :
