Amesim与matlab联合仿真，simulink运行时出现错误，matlab停止运行是怎么回事

This error was detected while a MEX-file was running.  If the MEX-file
is not an official MathWorks function, please examine its source code
for errors.  Please consult the External Interfaces Guide for information
on debugging MEX-files.
以上为错误提示，怎么解决啊，谢谢

有人可以解答一下吗，Amesim中的demo可以正常运行，但是自己建立的S函数模型就会出现错误

Simulink没有采用C语言
