之前的Centos7为了使用spectre提供的matlab toolbox，结果不小心删除了/usr/lib64中的某些动态库(XXXX.so文件)，导致重启之后内核崩溃。
这里送上忠告：尽量不要使用rm命令，使用mv命令改名备份最好。
于是进入了“漫长”的拯救数据行动，这里只给出主要思路：
由于清楚问题出现的原因，我首先是通过安装盘(U盘)进入拯救模式，然后拷贝了U盘核心中的动态库到原系统的动态库。此时原系统可以进入终端模式，但进入图形界面时登陆账户后就黑屏且重新回到登陆界面，并且终端中不能联网，也无法重新安装系统核心。看来系统应该很难救回来了，于是使用终端将关键数据进行打包，并挂载上移动硬盘将数据拷贝出来，此时数据拯救成功。
Centos系统虽已稳定著称，但同时也是个磨人的小妖精：常常为了解决各种依赖而耗费大量时间。因此决定转向支持更完善的Ubuntu系统，目前的使用证明Ubuntu是个老大哥，不再是小妖精了。Ubuntu的官方库完善，且在国内也能愉快地下载，再加上网络上已有很多Ubuntu安装Virtuoso的教程，因此Ubuntu是个不错的选择。
在Win下进入官网下载Ubuntu18.04，并制作安装U盘。建议使用UltralSO，点击即可下载。教程较多，不再赘述。
安装Ubuntu，我的分区如下（双系统）
| 挂载点 | 功能 | 大小 | 设置 |
|---|---|---|---|
| swap | 内存交换空间 | 12G | 主分区、空间起始位置 |
| /boot | 内核及引导文件位置 | 1G | 逻辑分区、空间起始位置、EXT4 |
| / | 根目录 | 40G | 主分区、空间起始位置、EXT4 |
| /opt | 第三方软件安装目录(自行安装) | 100G | 逻辑分区、空间起始位置、EXT4 |
| /usr | 官方软件安装目录 | 100G | 逻辑分区、空间起始位置、EXT4 |
| /home | 用户目录，存储数据 | 800G | 逻辑分区、空间起始位置、EXT4 |
更新内核、软件、驱动
# 更新软件
sudo apt-get upgrade
# 更新系统
sudo apt-get dist-upgrade
# 自动更新、下载驱动(可以自动安装Nvidia驱动，方便快捷)
sudo ubuntu-drivers autoinstall
不是真正的安装，是将我Centos系统中的Cadence软件库打包并解压过来的，真正的安装过程其他的博客讲的很清楚啦。
将软件包解压到/opt下
安装Virtuoso所需依赖
sudo apt-get install ksh ##安装ksh的shell
sudo apt-get install csh ##安装csh的shell
sudo apt-get install openjdk-8-jre openjdk-8-jdk ##安装openjdk jre等
sudo apt-get install xterm ##安装xterm终端模拟器
sudo apt-get install libncursesw5-dev ##安装libncursesw动态链接库
sudo apt-get install libxtst6:i386
sudo apt-get install libxi6:i386
sudo apt-get lib32ncurses5
sudo apt-get lib32stdc++6
sudo apt-get libstdc++5:i386
由于Virtuoso是基于Redhat系设计的，因此需要更改一些环境变量。
sudo ln -s /usr/bin/mawk /bin/awk
sudo ln -s /usr/bin/basename /bin/basename
sudo ln -s /lib/x86_64-linux-gnu/libncursesw.so.5.9 /lib/libtermcap.so.2
还需要让Virtuoso“认为”自己在Redhat上运行，在/etc中创建文件,
sudo gedit /etc/redhat-release
然后写入
Red Hat Enterprise Linux release 6.12
然后需要更改权限
sudo chmod 644 /etc/redhat-release
虽然Virtuoso官方文档建议使用csh配置变量和使用Virtuoso，但Ubuntu的csh使用并不方便，同时我使用csh+.cshrc的配置不能启动Virtuoso，因此我使用的是.bashrc+bash的配置。我的bashrc文件设置如下，请按需修改。
#+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
# For proper distributed processing execution using Cadence PVS software, it requires
# that the following is set as the first line in .bashrc
# Note: the space between the ! and $prompt is required!
#+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
if (! $prompt); then
exit
fi

修改Calibre的liscense.dat，主要是替换物理网卡的mac地址。
首先找到自己网卡的mac地址
ifconfig
第一张卡的mac地址复制即可，然后在下面文件中替换mac地址
sudo gedit /opt/Mentor_Graphics/calibre/aoi_cal_2018.4_34.26/license.dat
重启bash终端输入virtuoso即可运行。

电路中包含ahdlLib中的模块时，仿真失败。错误提示：
ERROR (VACOMP-1008): Cannot compile ahdlcmi module library. Check the log file input.ahdlSimDB/db40e45393110a6b15173cf850657951.diffamp.ahdlcmi/../ahdlcmi.out for details. If the reason for the failure was a syntax error, contact your Cadence Customer Support representative
观察ahdlcmi.out，其中报告的错误是
from diffamp.c:20:
/usr/include/math.h:27:36: fatal error: bits/libc-header-start.h: No such file or directory
#include <bits/libc-header-start.h>
查询后发现是由于该项目是在32位机器上生成的项目，若希望在64位机器运行需要安装gcc的multilib库，执行下面命令安装
sudo apt install gcc-multilib
然后即可完成包含ahdlLib库的仿真
Ubuntu18.04 安装配置 Cadence Virtuoso617
