"1. 你的机器名字是叫做localhost吗？
2 你的端口5200可以用吗？是否被其他的daemon占用了？
3 启动license daemon的时候把log 文件打开：lmgrd -c all_lic.dat -l /var/log/cds_lic.log, 再看看log 文件里面有没有出错信息
4 用lmutil -diag -c all_lic.dat来看看你要的feature是否可以check out"

答：
1. hostname 命令返回主机名：localhost.localdomain, 不过在/etc/hosts中设置主机别名为localhost.
    其实，LM_LICENSE_FILE=5200（在）localhost.localdomain{lic_root}/all_lic.dat 也没有跑通。
2. 通过ps命令发现仅有两个进程：bash和ps本身，估计端口没有被占用；另外，从后续的lmgrd指令运行的结果看也没有发现5200端口被占用。
3. /EDA/CADENCEUSR5/tools/bin/lmgrd -c all_lic.dat -l > lmgrd_return.log 输出的结果如下：

5. 发现两者的结果有些矛盾，是不是？一个说无效，一个说是correct, 只是后者提示“node-locked”,是不是解决该问题的突破口

其实Cadence需要看到CDS_LIC_FILE这个环境变量就可以了，这里的LM_LICENSE_FILE起到了混淆的作用，应该预留这个环境变量给Mentor公司的软件。而且你不一定要运行lmgrd再运行Cadence, 只要CDS_LIC_FILE设置好，就直接启动Cadence, 看看行不行。

看lmgrd的结果，这个license绝对不是一个正确的license 文件。后面的都别提了。

建议你找一个合适的licesne 文件，应该就没有问题了。

你好，我用AMS跑一个PLL的workshop时，也遇到了类似问题：
Trying to check out license...
                  Virtuoso_Multi_mode_Simulation 7.0 - Successful
                  AMS_Designer_Verification 8.2 - Failed
ncsim: *F,NOLICN: Unable to checkout license for the simulation. (flag -18 ) 'lic_error -97'
但是单独用ncsim跑了一个例子，可以通过：
[xxx /home/xxx/project/sim_cos_rom]$run.bash
ncvlog(64):08.20-s012: (c) Copyright 1995-2009 Cadence Design Systems, Inc.

ncsim(64):08.20-s012: (c) Copyright 1995-2009 Cadence Design Systems, Inc.
ncsim> run 1ms
不知道如何处理了？楼主可解决了这个问题没？

跪问 ：cadence中用ams进行数模混合仿真过程中，仿真进行到7.多ms就停止了，出现如下错误

ncsim:*E,SST2ER:SST2 interface error:conflicting variable association

ncsim:*F,INTERR: INTERNAL ERROR

observed simulation time:7784550629507FS+1

几次仿真的结束时间都是不一样的，但都很接近，冰天雪地跪求大神帮忙

是否是波形文件太大了，换个格式存波形
