从Spartan-6 CSG484LX150输出数据时出现错误

嗨，
当我尝试从Spartan-6 CSG484LX150输出数据时出现以下错误：
错误：位置：1318  - 用户具有过度约束的组件serializeData_oser_driver。
没有可放置的站点满足用户约束。
请查看驱动程序组件的用户约束以及serializeData_oser_driver的加载组件。
serializeData_oser_driver是一个驱动6个OSERDES的BUFPLL。
每个OSERDES驱动一个名为oData的std_logic_vector元素，它是输出向量。
我验证了“Spartan-6 FPGA封装和引脚产品规格UG385（v2.2）2011年8月24日”，以确保连接到oData的所有引脚都属于同一个IOBank（编号2）。
ucf文件位于此消息的末尾。
我不知道什么是错的。

先谢谢你，

Hi,

I'm having the following error when I try to output data from a Spartan-6 CSG484LX150:

ERROR:Place:1318 - User has over-constrained component
   serializeData_oser_driver. There are no placeable sites that satisfy the user
   constraints. Please review the user constraints on the driver component and
   the load components of serializeData_oser_driver.

serializeData_oser_driver is a BUFPLL that is driving 6 OSERDES. Each OSERDES drives a element of a std_logic_vector named oData, which is the output vector.
I verified "Spartan-6 FPGA Packaging and Pinouts Product Specification UG385 (v2.2) August 24, 2011" to be sure that all pins connected to oData belong to the same IOBank (number 2). The ucf file is at the end of this message. I don't know what could be wrong.
