Pack:1107 ERROR

Hey. I am using two Spartan 6 FPGA (XC6SLX150T-2FGG484C) in my board.

I used MGTTXN0_123,MGTTXP0_123 pins (TX-,TX+) and MGTRXN0_123,MGTRXP0_123 pins (RX-,RX+) between these two FPGA for high speed cross link.

1- Can I used these pins for communication between 2 FPGAs?

2- I tried to implement my FPGA project using Spartan 6 and used IBUFDS and OBUFDS for these pins. But I could not implement design. I see this error : Pack:1107 - Pack was unable to combine the symbols listed below into a single IOBS component because the site type selected is not compatible.

Re: Pack:1107 ERROR

Hello @ydelican123 
I hope you are doing fine.

>Can I used these pins for communication between 2 FPGAs?

Yes. Spartan-6 GTP can support up to 2.7Gbps or 3.2Gbps max line-rate (depends on device speed grade)

>I see this error : Pack:1107 - Pack was unable to combine the symbols listed below into a single IOBS component because the site type selected is not compatible.

1. MGTTXN0_123,MGTTXP0_123 pins (TX-,TX+) and MGTRXN0_123,MGTRXP0_123 pins (RX-,RX+) are GTP pins.
( This is not an ordinary IO pins )

2. If you are new to Xilinx Transceivers, You may find these document very helpful.

3. IBUFDS, OBUFDS is not compatible with GTP pins,
    If you want to use IBUFDS/OBUFDS you should use non GTP pins. ( see also UG385 )
