Quartus 打开RTL Viewer时出现*** Fatal Error: Int Divide By Zero Module: quartus.exe Stack Trace: 0x103

具体的一张错误如下图：

 

可能你的错误不是这样的，但是会出现Fatal Error。

 

具体解决方法：

  intel官网解释：

Internal Error: Sub-system: RVD, File: /quartus/rtlv/rvd/rvd_netlist_component.cpp, Line: 9067

Description

Due to a problem in the Quartus® II software version 13.0 Web Edition, you may see this internal error when launching the RTL Viewer.

Workaround/Fix

To work around this problem, edit your project Quartus II Settings File (.qsf) to include the following line (or modify this setting if the line is already in your .qsf): 

set_global_assignment -name RTLV_GROUP_RELATED_NODES ON

This problem is scheduled to be fixed in a future release of the Quartus® II software.

 

所以我们把

    set_global_assignment -name RTLV_GROUP_RELATED_NODES ON

添加到工程的qsf文件中即可。然后编译就可以正常查看RTL图了

 

我的Quartus是13.1，这应该是一个软件的bug，与你的代码没有关系。

 

2、可能添加后还有Fatal Error

然后按下图配置试一下（度娘）：
