关于quartus ii直接调用modelsim仿真

之前自己也遇到这类问题，然后上网找，最后也没能解决。直接进行rtl仿真会收到这样的报错信息

connot launth the modelsim-altera softwarre because you did not specify the path to the executables of the modelsim-altera softwarre

然后如果在option---eda tool options   里面指定的是自己装的modelsim路径的话，会出现这样的信息。

     Error: Can't launch the ModelSim-Altera software -- the path to the location of the executables for the ModelSim-Altera software were not specified or the executables were not found at specified path.

正确的做法是定义quartusii 安装路径里面的modelsim.exe的路径，比如我的是在D:\quartus\modelsim__ase\win32aloe，

之后就能进行仿真了。
