用VHDL语言编写程序

用VHDL语言编写程序,第1张

我用quartusⅡ凯敏已编译嫌链并且仿真都对的,我写的是0亮1灭,如果实际情况与这相反,你自己倒一下。

std_logic_vector type does not match integer literal这个错误是说std_logic_vector类型与整形不匹配 主要原因是因为你的q1<= q1+1这句 std_logic_vector不能直接做加法运算。需要先转换成整型饥差,运算之后再转换回来,这需要调用conv_integer 和 conv_std_logic_vector这两个函数。

至于其他还有很多语法错误 不多赘述 我在程序中直接给你做了更改 注意if的匹配
