Error

I was trying to execute Mentor Modelsim/Questa in Ubuntu 18.04 but it returns the following error message:

Error in startup script: 
Initialization problem, exiting.

Initialization problem, exiting.

    while executing
"InitializeINIFile quietly"
    invoked from within
"ncFyP12 -+"
    (file "/mtitcl/vsim/vsim" line 1)
** Fatal: Read failure in vlm process (0,0)

That's because required library dependencies are up-to-date in Ubuntu 18.04.

Answer 😍

To solving that problem is installing libfreetype6 and libpng12. First you need to add 32 bit lib options:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install build-essential
# You already had build-essential and gcc, g++ etc. But you will also need to install the 32 bit versions.

Those libs are up-to-date in Ubuntu 18.04, so we need to download the Modelsim/Questa compatible libraries:

MODELSIM DEP LIBS

wget http://security.ubuntu.com/ubuntu/pool/main/libp/libpng/libpng12-0_1.2.54-1ubuntu1.1_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/main/libp/libpng/libpng12-0_1.2.54-1ubuntu1.1_i386.deb
wget http://archive.ubuntu.com/ubuntu/pool/main/f/freetype/libfreetype6_2.6.1-0.1ubuntu2_i386.deb
wget http://archive.ubuntu.com/ubuntu/pool/main/f/freetype/libfreetype6_2.6.1-0.1ubuntu2_amd64.deb
sudo dpkg -i libpng12-0_1.2.54-1ubuntu1.1_i386.deb
sudo dpkg -i libpng12-0_1.2.54-1ubuntu1.1_amd64.deb
sudo dpkg -i libfreetype6_2.6.1-0.1ubuntu2_i386.deb
sudo dpkg -i libfreetype6_2.6.1-0.1ubuntu2_amd64.deb 

Obs.: Make sure all libs was successfully installed.

Also, you must guarantee the installation of the following libs:

sudo apt-get install gcc-multilib g++-multilib \
lib32z1 lib32stdc++6 lib32gcc1 \
expat:i386 fontconfig:i386 libfreetype6:i386 libexpat1:i386 libc6:i386 libgtk-3-0:i386 \
libcanberra0:i386 libpng12-0:i386 libice6:i386 libsm6:i386 libncurses5:i386 zlib1g:i386 \
libx11-6:i386 libxau6:i386 libxdmcp6:i386 libxext6:i386 libxft2:i386 libxrender1:i386 \
libxt6:i386 libxtst6:i386

✔️ After that, Modelsim/Questa works normally.

Xilinx has launched the ISE Software Design Software Package to optimize power and cost, as well as to increase the efficiency of its software in the market. For the first time, ISE design tools provide smart clock-gating technology for its users. This technology reduces power consumption by up to 30%. This technology is implemented through the analysis of designs and using a set of unique algorithms to identify consecutive elements. The new software suite also includes improvements to timing-driven design reservation, support for plug-and-play design, and a fourth-generation visual design streaming feature that reduces system costs for a wide range of applications. The above can be provided.In fact, this software is an industry-proven solution for all Xilinx programmable devices, including the 7 Series and the previous 7 Series and Zynq ۷ -7000 devices. The software package fully supports Xilinx Virtex-6 and Spartan-6 FPGA families.

You can design much faster than before by accessing highly parameterized IPs for Xilinx FPGAs and ISE Design Suite. Highly optimized IPs allow FPGA designers to focus more quickly on design.With this software, you can rely much more on digital signal processing functions. One of the most important benefits of ISE Design Suite is activating the use of accelerators by the processor. In fact, one of the most important benefits of FGPA's special design system is the ability to run system partitions and manage trade offs in a software. With this software, you can create your own processing platform at a low cost by consolidating external functions in an FPGA.
