ise place route报错

陆琦

麻烦请问各位大侠，在Xilinx place & route 时出现：1 signals are not completely routed 但是并没有提示Error message。另外这个PCI IP核单独布线时是没有问题的，我将其他子模块加进来就出现不满足的情况了。

Phase  2  : 11034 unrouted;      REAL time: 40 secs
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:
