Xilinx ISE综合项目时报“INTERNAL_ERROR”故障一例

故障描述:用户使用运行于Windows 10 x64上的ISE编译一个使用Verilog编写的项目,在综合(Synthesize - XST)阶段失败并报错:

INTERNAL_ERROR:Xst:cmain.c:3464:1.56 - Process will terminate. For technical support on this issue, please open a WebCase with this project attached at http://www.xilinx.com/support.

该错误无前置错误消息,检查设备内存使用正常

故障排除:首先尝试执行“Project -> Cleanup Project Files”命令,无效。

随后,右键单击“Synthesize - XST”过程,打开综合器属性设置,将右下角的“Property display level”设为“Advanced”,在“Other XST command line options”中加入:

-use_new_parser yes

保存设置,再次执行综合,故障解决。
