如何添加外部时钟斯巴达6？

嗨，
包名称包含的确切设备是什么？
您需要在引脚分配用户指南中检查它是否具有时钟能力。

Spartan-6 FPGA引脚定义表将指导您了解引脚名称的编码。
如果您将时钟馈送到非时钟引脚，您将看到时序故障和其他问题，因为该工具将无法以较少的偏斜路由它。
问候，

Hi ,
 
What is the exact device includong the package name ?
You need to check if it is a clock capable io or not in the pinout userguide.
http://www.xilinx.com/support/documentation/user_guides/ug385.pdf
 
Spartan-6 FPGA Pin Definitions table will guide you to understand the encoding of pin names.
 
If you are feeding a clock to a non clock capable pin you will see timing failures and other issues as the tool lwill not be able to route it with less skew.

你好MSD，
你可以尝试使用p124而不是p123来看看它是否有效。

Hi MSD,
 
can you try with p124 instead of p123 to see if this works.
