GLOCK输入错误该如何解决？

嗨，我想使用GLK输入来传输一些不同的数据。
所以我尝试将OBUFDS输出连接到时钟输入的专用引脚。
它是sp601开发板中唯一连接到SMA连接器的引脚，我需要连接一个SMA。
我没有真正选择将我的输出映射到其他引脚。
我在映射操作期间出现以下错误：
错误：位置：1333  - 具有输入/输出编程的IOB锁定到不支持此类值的存储区1 IO标准：名称= LVDS_25，VREF = NR，VCCO = 2.50，TERM = NONE，DIR = OUTPUT，DRIVE_STR
= NR锁定的IOB列表：link1TxPadN_o link1TxPadP_oERROR：Pack：1654  - 时序驱动的放置阶段遇到错误。
我检查了bank1中引脚的电压，看起来是正确的。
所以我不确定是否有可能做到这一点。
有些机构有关于此的明确信息吗？
提前致谢，
丹尼尔

Hi,

I'd like to use a GLK input to transfert some diffenrential data. So I try to connect my OBUFDS ouputs to the dedicated pin of the clock input. It is the only pin witch is connected to SMA connector in the sp601 dev board and I need to use an SMA connected. I don't have realy the choice to map my ouputs to others pins. I have the following error during the mapping operation:

ERROR:Place:1333 - Following IOB's that have input/output programming are locked
   to the bank 1 that does not support such values
   IO Standard: Name = LVDS_25, VREF = NR, VCCO = 2.50, TERM = NONE, DIR =
   OUTPUT, DRIVE_STR = NR
   List of locked IOB's:
       link1TxPadN_o
       link1TxPadP_o
ERROR:Pack:1654 - The timing-driven placement phase encountered an error.

I check the voltage of the pin in the bank1 and it seems correct. So I'am not sure that is possible to do this. Is some body has clearly information about this?

Thanks in advance,

Daniel
