interconnection between PCIE and FPGA pin

[topxuxiang8]

Hi everyone,

In VC709 board I found the interconnection between FPGA serial io and PCIE's is 

 

For example 'PCIE_TX3_P' connects to MGTHTXP0，but why not MGTHTXP3. 

Who can tell me why the connection is like that ? 

Thank you so much

Have a read of PG054 Chapter 4, the "Recommended GT Locations" section (p.225 onwards) shows you the recommended GT locations for different devices.
