这位同学,你用的综合工具应该不是quartus,呵呵。
我刚刚用QuartusII编译了一下你的程序。他也提示waring,
Warning: Design contains 1 input pin(s) that do not drive logic
Warning (15610): No output dependent on input pin "din[0]"
我分析 因为你输出结果与你的某一个管脚状态无关。也就是你在设计这个logic
有个冗余项
还有waring,提示Warning: No exact pin location assignment(s) for 6 pins of 6 total pins
Info: Pin din[0] not assigned to an exact location on the device
Info: Pin dout[0] not assigned to an exact location on the device
Info: Pin dout[1] not assigned to an exact location on the device
Info: Pin din[2] not assigned to an exact location on the device
Info: Pin din[1] not assigned to an exact location on the device
Info: Pin din[3] not assigned to an exact location on the device
这个原因是,你综合完后,没有分配引脚,我再Quartusii中分配引脚后,就没有这个waring了。
呵呵,我只能帮这么多了,希望对你有帮助~我QQ515475925,可以细谈~
