用Xilinx ISE10.实现Leon3的问题

我使用Xilinx10.对Leon3的soc系统进行综合实现，到了实现那里，翻译、映射都通过了，就是到了布局布线时产生了错误，错误提示为：
Constraints file: leon3mp.pcf.

我想应该不是我的版本不合格吧，不然前几个阶段就应该不能进行了。是不是我哪里设置的不合格，出现了这样的问题呢?请求高手指点一下啊

求解……

求助 LEON3软件开发环境

你用的应该是evaluation 版本的吧

路过看看，，

ERROR par:332 - The evaluation period for this evaluation software has expired.
软件到期了

小编在吗?请问下我在第一步中遇到library grlib cannot found 的问题，能否指教，万分感谢。
