ise在布局布线时出现以下错误：Phase  2  : 59979 unrouted; WARNING:Route:436 - The router has detected an unroutable situation for one or more connections. The router will finish the rest of the
   design and leave them as unrouted. The cause of this behavior is either an issue with the placement or unroutable placement constraints.
   To allow you to use FPGA editor to isolate the problems, the following is a list of (up to 10) such unroutable connections:

求大神指导以下啊

这个主要是布线资源不够造成的。

看上去都是chipscope的布线

试试减掉一些信号，压缩下chipscope的占用资源
