VHDL编译出现如下的问题怎么解决
Warning:Output pins are stuck at VCC or GND
\x05Warning (13410):Pin "sound" is stuck at GND
\x05Warning (13410):Pin "q[2]" is stuck at GND
\x05Warning (13410):Pin "q[1]" is stuck at GND
还有Warning:Following 3 pins have nothing,GND,or VCC driving datain port -- changes to this connectivity may change fitting results
\x05Info:Pin sound has GND driving its datain port
\x05Info:Pin q[2] has GND driving its datain port
\x05Info:Pin q[1] has GND driving its datain port

Answer 1

Warning:Output pins are stuck at VCC or GND
\x05Warning (13410):Pin "sound" is stuck at GND
\x05Warning (13410):Pin "q[2]" is stuck at GND
\x05Warning (13410):Pin "q[1]" is stuck at GND
这个的意思是您的这几个输出管脚直接接地了（意思是它们的值一直都是0）.当然如果这符合您的设计要求这种警告可以不管.
Warning:Following 3 pins have nothing,GND,or VCC driving datain port -- changes to this connectivity may change fitting results
\x05Info:Pin sound has GND driving its datain port
\x05Info:Pin q[2] has GND driving its datain port
\x05Info:Pin q[1] has GND driving its datain port
这几句的意思是您没有对这三个信号进行驱动.
