Modesim仿真错误！！！！ [复制链接]

在quartus 2中用Verilog语言编写了个驱动LCD1602的模块的顶层文件，在ModelSim中仿真问什么会有以下这样的提示呀？

 

Note:E/examples/lcdd/lcd1602_test.vhd(154): (vopt-1129) Type mismatch for generic "S0" of component "lcd1602_drv" when binding to entity "lcd1602_drv".

上面警告告诉你：你的LCD1602_drv 在MODESIM仿真过程中，传递传输时S0,S1,S2参数类型不匹配！
