Cadence VLSI Software installation under Ubuntu/Debian 64 bits
Cadence Software Under Fresh 64bits Ubuntu/Debian System
Environment
Search and install packages in Ubuntu/Debian:
sudo apt-get search package sudo apt-get install package
Ubuntu 13.10 64bits fresh install.
List of packages needed/recommended
build-essential
openjdk-8-jre (or java-7-jre)
xfonts (100dpi, 75dpi), ttf-freefont
ssh-server
libstdc++6
You need to define some . You can put them in your
~/.bashrc file
Therefore, you can install them by typing in a terminal:
sudo apt-get install ksh build-essential openjdk-8-jre vim aptitude csh ssh lsb-core libstdc++6 xfonts-100dpi xfonts-75dpi xfonts-100dpi-transcoded xfonts-75dpi-transcoded ttf-freefont sysstat
Restart the system. Now you are able to install Cadence Software
Cadence SW Installation
The following installation steps are extracted and customized from the guide EUROPRACTICE Cadence IC Package Licensing & Installation .
Previous considerations
It is possible that some downloaded files are compressed into '.Z' file format. You can uncompress them using
zcat file.t.Z | tar xvf -
Installing Cadence Software Using IScape
Now, execute iscape typing
sh iscape.sh
Posible Problems and Solutions
If during the installation process you get permission errors, execute iscape with privileges:
sudo sh iscape.sh
If installscape does not work showing a java error message, you need to link the java, java_vm y javaws binaries in /etc/alternatives maintaining the same names. You can also update the java references by executing:
sudo update-alternatives --config java sudo update-alternatives --config javac sudo update-alternatives --config javws
Additionally, it is possible that iscape.sh is outdated for your system,
iscape.sh: 219: exec: /home/administrador/cadence_install_files/iscape.04.21-s003/runtime/LNX86/bin/java: not found
If you get the above error, you need to edit iscape.sh and change
.... if [ "X$java_vm" = "X" ]; then java_vm=`FindJavaInPath`;
if [ "X$java_vm" = "X" ]; then java_vm=`FindJavaInPath`; java_vm=Path_to_your_java_bin_folder // in this case, /usr/lib/jvm/java-7-openjdk-amd64/bin/java
Step by Step
First of all, we need to install INCISIVE. Incisive is responsible for the compilation of different libraries. After this step, we would be able to install the other software tools, as IC, MMSIM etc.
The Incisive suite contains simulation & verification tools for digital and mixed signal designs. It is also required for the compilation of AMS Designer libraries during the IC 6.1.x installation. For this reason, Incisive should be installed before any other release.
Due to this requirement, the recommended installation order is the following:
The different tools (including INCISIVE) can be installed using IScape:
Click on &Install from a Local Directory/Media& in the InstallScape window.
When asked for a location, choose ALLWAYS the "Hotfix" (Or "Update") CDROM1 directory. The InstallScape installer will ask you later (if needed) for the "Base" directory.
Click &Next&. When asked what products to install. For example, if using the hotfix cdrom directory, once the installation gets to ~99% InstallScape will ask you for the Base ICxx directory. Simply point it to the CDROM1 folder in base folder (~/CADENCE_INSTALL/ICxx/Base/ICxx_lnx86.Base/CDROM1) from your installation sources.
Once done, an installation Report will show you the results of your installation.
The configuration process should now start. Select the desired license options, and path.
When dealing with OpenAccess software, follow the instructions located in the Europractice pdf. For
software they recommend to use the open access binary (and therefore, the path) located inside each tool folder.
Click &Close&. You will be prompted to configure the installed products. Click &Yes&
An automated configuration script will now start.
The desired software should now be installed.
Open Access Versions During the configuration of each release, you may be invited to specify a different OpenAccess installation. The recommended action is to use the OpenAccess Version installed with the tool, so in each case, answer no, as shown below.
Welcome to the OpenAccess 2.2 Configuration Utility. Important: Before continuing, first close all applications that use OpenAccess libraries. Then make sure that there are no oaDMTurboServer processes running (kill these processes with the kill command on UNIX/Linux). Press Enter to continue (q to quit): ------------------------------------------------------------------------------- This utility lets you specify a different OpenAccess installation to use. The current installation is [/pack/cadence//IC_6.1.5HF132/oa_v22.41.025] Do you want to use a different OpenAccess installation (y/n/q) ? [y] n

Post Installation
There are several changes which must be taken to get the software correct behavior. Note that it is posible that the following commands require sudo privileges.
Backup $CDS_IC/tools/bin/cds_root
sudo cp $CDS_IC/tools/bin/cds_root $CDS_IC/tools/bin/cds_root.32b.back
Now, link cds_root to the 64bits edition
sudo rm $CDS_IC/tools/bin/cds_root
sudo ln -s $CDS_IC/tools/bin/64bit/cds_root $CDS_IC/tools/bin/cds_root
sudo ln -s /usr/bin/awk /bin/awk
Dash link to bash
sudo ln -sf bash /bin/sh
To revert it:
sudo ln -sf dash /bin/sh
Compiler and libraries
In order to use
ahdlcmicompile support (BSources and other behavioral components)
ADEXL (uses vnclibs)
You need to properly configure your system.
cd $CDS_IC/tools/bin mv lmgrd lmgrd.old ln -s 64bit/lmgrd lmgrd ln -s 64bit/lmutil lmutil
GCC compiler
Note that the path $CDS_MMSIM/tools.lnx86/cdsgcc/gcc/4.4/bin can be upgraded to any $CDS_MMSIM/tools.lnx86/cdsgcc/gcc/X.Y/bin Redirect cadence gcc to use system gcc instead:
cd $CDS_MMSIM/tools/cdsgcc/gcc/bin mv gcc gcc_bak mv g++ g++_bak mv ld ld_bak mv c++filt c++filt_back ln -s `which gcc` gcc ln -s `which gcc` g++ ln -s `which gcc` ld ln -s `which gcc` c++filt cd $CDS_MMSIM/tools/cdsgcc/gcc/4.4/bin mv gcc gcc_bak mv g++ g++_bak mv ld ld_bak mv c++filt c++filt_back ln -s `which gcc` gcc ln -s `which gcc` g++ ln -s `which gcc` ld ln -s `which gcc` c++filt
Redirect cadence make to use system make instead:
cd $CDS_MMSIM/tools/spectre/ahdlcmi/bin/ mv gnumake gnumake.back ln -s /usr/bin/make gnumake
Compiling libraries
You can install gcc 32bits libraries (NOT RECOMMENDED)
sudo apt-get install gcc-multilib
Or you can properly configure your 64 bits native ones RECOMMENDED. The following environment variables should be configured as follows:
LIBRARY_PATH=/usr/lib/$(gcc -print-multiarch):/usr/lib/x86_64-linux-gnu:/usr/lib:/usr/bin/gcc:$CDS_IC/tools/bin:$CDS_IC/tools/lib/64bit:$CDS_IC/tools/dfII/lib/64bit:$CDS_IC/tools/sev/lib/64bit CPATH=/usr/include/$(gcc -print-multiarch) export LIBRARY_PATH CPATH
You need to find libgcc in your system (maybe it is placed in /usr/lib/x86_64-linux-gnu/libgcc_s.so.1 or in /usr/lib/libgcc_s.so.1 Next, modify the different cadence software links:
cd $CDS_IC/tools/lib/vnclibs/
mv libgcc_s.so.1 libgcc_s.so.1.old
ln -s /lib/x86_64-linux-gnu/libgcc_s.so.1 libgcc_s.so.1

mv libgcc_s.so libgcc_s.so.old
ln -s /lib/x86_64-linux-gnu/libgcc_s.so.1 libgcc_s.so
libstd (c++ standard libraries)
You need to find libstd in your system (maybe it is placed in /usr/lib/x86_64-linux-gnu/libstdc++.so.6 or in /usr/lib/libstdc++.so.6 Next, modify the link of cadence software
cd $CDS_IC/tools/lib/
mv libstdc++.so.6 libstdc++.so.6.old
ln -s /lib/x86_64-linux-gnu/libstdc++.so.6 libstdc++.so.6

Cadence under a 64 bits Ubuntu/Debian with 32bits libs, with IC already installed
Previous considerations
If possible, we recommend
with a fresh install of the latest Ubuntu 64bits version instead of a 12.04 release. If you have an Ubuntu 12.04 64bits machine, with IC5 already installed and you experiment ahdlc compiling problems, follow this one.
Environment
The environment for this guide is an Ubuntu 12.04 64bits machine with IC5 and MMSIM11 already installed, as well as the following libraries/programs:
Ubuntu 13.10 64bits fresh install.
List of packages needed/recommended
build-essential
openjdk-7-jre
xfonts (100dpi, 75dpi), ttf-freefont
ssh-server

libXP Both 64bits and 32bits
libExt Both 64bits and 32bits

libc6-devBoth 64bits and 32bits
libstdcBoth 64bits and 32bits

elfutils-libelf
mesa-libGL
mesa-libGLU
You need to define some . You can put them in your
~/.bashrc file
Installing ahdclc in a 64/32 bits Ubuntu 12.04
Please, notice that the following commands will use, contrary to the previous guide, 32 bits libraries when compiling behavioral components.
sudo aptitude install gcc-multilib
Post Installation
Move to your MMSIM folder
sudo mv gcc gcc.old sudo mv g++ g++.old sudo mv ld ld.old sudo ln -s /usr/bin/gcc gcc sudo ln -s /usr/bin/gcc g++ sudo ln -s /usr/bin/gcc ld

我有更好的答案
而32位iTunes则可以运行于X86和64位系统64位iTunes只能运行在64位操作系统下，系统类型一栏，如果标示64位操作系统，那么就推荐你下载64位iTunes，以发挥系统的最大性能，查看系统版本的方法是，Win7下右键我的电脑，查看属性，如果不是显示64位操作系统
