Install Modelsim on a 64-bit (x)Ubuntu

wget http://download.altera.com/akdlm/software/acdsinst/13.1/162/ib_installers/ModelSimSetup-13.1.0.162.run
chmod +x ModelSimSetup-13.1.0.162.run

However, the free version of Modelsim Altera Edition is 32-bit only. We need to install some dependencies:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install build-essential
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 libpng16-16: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

Next, we need to build a free version of FreeType:

wget http://download.savannah.gnu.org/releases/freetype/freetype-2.4.12.tar.bz2
tar -xjvf freetype-2.4.12.tar.bz2
cd freetype-2.4.12
./configure --build=i686-pc-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"
make -j$(nproc)

Then, install Modelsim:

1

sudo ./ModelSimSetup-13.1.0.162.run

Note: I’ll assume that Modelsim is installed in opt/modelsim for the next steps. Copy the FreeType libraries in Modelsim folder:

1

3


cd /opt/modelsim/modelsim_ase
sudo mkdir lib32
sudo cp ~/freetype-2.4.12/objs/.libs/libfreetype.so* ./lib32

Modify the `bin/vsim` script

Step 1 - Path to the FreeType folder

Search for the following line:

1

dir=`dirname $arg0`

and underneath add the following new line:

1

export LD_LIBRARY_PATH=${dir}/lib32

Step2 - Modify the RedHat only support

Search for the following string:

1

vco="linux_rh60"

and replace by:

1

vco="linux"

Step 3 - Change VCO mode

Search for the following line:

1

mode=${MTI_VCO_MODE:-" "}

and replace by:

1

mode=${MTI_VCO_MODE:-"32"}
