ADS的直流仿真出错，好像是license的问题。

    
    我在参考《ADS射频电路设计》上的例子，做一个很简单的DC仿真，然后出错了，eetop.cn上也有这种情况，不过没找到有价值的解决方案。不知道你有没有遇到过，出错信息附在后面了。那个license，昨天安装ADS的时候已经提示安装成功了，不知道为啥还会出错。

Simulation Messages
Error detected by hpeesofsim during circuit set up `Sweep1'.
    An appropriate license for linear features is not available.  This
    feature must be licensed before it can be used.
        FlexLM error message:
        Linear Simulator
        
        The desired vendor daemon is down
        
        Possible Causes:
        1. lmgrd process is running, but not the agileesofd vendor daemon. The software was able to contact the license server (lmgrd), but the vendor daemon (agileesofd) did not respond.
        2. agileesofd vendor daemon has crashed or has been terminated.
        3. lmgrd process was shut down manually or via LMTools with -x lmdown option
        4. On Windows platform, this could be caused by waking up from Sleep or Hibernation mode.
        5. The logfile was unable to be removed.
        
        Troubleshooting Tips:
        1. Check the license server's debug log file and try lmreread.
        2. Reboot your system to restart the license service.
        3. Use LMTools to clear your previous setup first, then restart license setup wizard to re-configure your license.
        4. Shut down the lmgrd process and check that lmgrd or agileesofd processes are no longer running. Restart the license server.
        5. Stop lmgrd via kill pid (UNIX) withough -9 argument or stop the lmgrd process through the Windows Task Manager or Windows Service.
        6. Close all processes that are reading the logfile.

这个把license和安装的软件放在一个文件夹里试一下，看是否有用

这个license之前就是放在ADS安装路径下的。
