只看该作者 · 2011-3-20 19:10

我写了个编解码程序，仿真通过了，但是下载到开发板之后没反应。在 place and route report里面，有如下内容(既不是warning也不是error)：
Starting Router

Phase 1: 26182 unrouted;    REAL time: 1 mins 27 secs

Phase 2: 24668 unrouted;    REAL time: 1 mins 28 secs

Phase 3: 14164 unrouted;    REAL time: 1 mins 31 secs

Phase 4: 14164 unrouted; (439563)    REAL time: 1 mins 32 secs

Phase 5: 14188 unrouted; (0)    REAL time: 1 mins 33 secs

Phase 6: 0 unrouted; (32794)    REAL time: 2 mins 50 secs

Phase 7: 0 unrouted; (32794)    REAL time: 2 mins 52 secs

Phase 8: 0 unrouted; (0)    REAL time: 2 mins 54 secs

Total REAL time to Router completion: 2 mins 54 secs
Total CPU time to Router completion: 2 mins 52 secs

这里面提到的unrouted很模糊，具体是什么意思啊？望各位过路大侠指点迷津，不胜感激！！！！
