Ubuntu18.04 安装配置 Cadence Virtuoso617

时间：2024-02-21 17:45:57

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。

安装Ubuntu18.04

  1. 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。

  2. 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

  3. 更新内核、软件、驱动

    # 更新软件库
sudo apt-get update
# 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

安装、配置Cadence Virtuoso

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。

  1. 将软件包解压到/opt下

  2. 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 install lib32ncurses5 
sudo apt-get install lib32stdc++6 
sudo apt-get install libstdc++5:i386

  3. 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

  4. 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

  5. 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

  6. 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

  7. 重启bash终端输入virtuoso即可运行。

遇到的问题和解决方案

该板块会记录使用过程中遇到的问题和解决办法，如有新问题会及时更新。

  • 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

  • 运行Calibre时出现以下提示(2020.11.20)

    error while loading shared libraries: libXp.so.6: cannot open shared object file: No such file or directory

    搜索后发现是libXp.so.6库没有安装，使用apt安装时发现不能定位到该软件包。于是选择手动安装。该库的名字为libxp-dev_1.0.1-2_amd64.deb和libxp6_1.0.1-2_amd64.deb。下载好使用dpkg -i 命令安装即可，若遇到依赖问题可使用以下命令解决，然后重新安装。

    sudo apt-get install -f

    安装完成后Calibre正常工作。
    运行Calibre后仿PEX时，无法生成原理图，有以下提示(2021.05.08)

Calibre View generation encountered a fatal Error. Please consult the logfile for messages.

这个问题困扰我一年有余，期间尝试过各种方法：

  1. 在环境变量中添加：MGC_FDI_OA_VERSION = 22.50
  2. 设置共享文件夹：LD_LIBRARY_PATH
  3. 更换最新版本Calibre

但三种方案都不能解决问题，今日发现新的方案，遂解决，方案如下：

在环境变量中加入一行：

export CALIBRE_ENABLE_SKILL_PEXBA_MODE = 1

重启VIrtuoso发现问题解决。
