求助，Cadence Vituoso不联网就不能启动

我安装了IC614 和MMSIM72，也装了NCSU的CDK 1.6版。最近发现如果不联网，virtuoso就不能启动，一直等待大约5分钟才报错，下面是log文件。请问有什么办法能解决吗，谢谢。

有朋友建议我检查hosts文件
我看了，我把local address设为127.0.0.1了，license文件里也是
也有建议把cdsenv和cdsinit删掉的，但是那样当我打开与NCSU有关的layout时，就会报错，而且如果没有联网，仍然打不开virtuoso
求助啊。

个人观察发现主要是这两句耽误了很久，不知道它们要联网做什么

顶一下

碰到过一次类似的情况，是网络中IP地址冲突，license启动会出故障，EDA工具检测license文件的时候就会报这种问题。网络中如果主机名相同或者网卡号相同，也会出同样的问题。

谢谢回复
问题是联网时没有问题，断网时不能启动
所以我觉得不是IP地址的问题吧。

linux系统对硬件依赖性度还是很强的，安装好系统之后，如果更换了硬件或者硬件没有连接到主机上（例如鼠标和键盘），都会报错，机器越高档，硬件检测越严格。情况好的话，等一会儿会自动跳过，继续执行。网络没有连接的情况通常不容易自动跳过（solaris系统可以跳过），通常会报IPC（进程间通信）初始化失败，曾经用过的一个办法（交换机被雷击坏了）：安装虚拟网卡进行虚拟网络连接（RedHat系统用过），或者卸载网卡驱动（license文件中要求主机网卡号hostid项支持ANY，SUSE系统用过）。

楼上，我想你说的是对的，呵呵，我几乎没用过linux，现在用的是ubuntu 10.10
Waiting for ipc:0 to initialize，这是后面的报错，等了很久说尝试了60次失败
不过最一开始卡住的是这句
\w *WARNING* Unable to export thumbnail MPS services

小编解决了吗，我也遇到相同的问题，怎么解决啊

解决了。联网呗。
