This description assumes that version 13.0sp1 is already installed on Lubuntu 18.04. The Quartus 18.1 version is used only by the Master Course.

Download Quartus-lite-18.1.0.625-linux.tar from Intel. You can download with

cd
cd cae
wget --user=YOURUSERNAME --ask-password  https://www.hs-augsburg.de/~beckmanf/restricted/Quartus-lite-18.1.0.625-linux.tar

Check that you have

• Installed the missing libpng12

Make sure that you install the software at “/opt/altera/18.1”. When you run the installation, you can deselect all FPGA device families, except Cyclone V.

tar -xvf Quartus-lite-18.1.0.625-linux.tar
./setup.sh

Check that you have

• Compiled the libfreetype library

and copy the library to the 18.1 directory

mkdir /opt/altera/18.1/modelsim_ase/lib32
cp ~/cae/freetype-2.8.1/objs/.libs/libfreetype.so* /opt/altera/18.1/modelsim_ase/lib32/

Change /opt/altera/18.1/modelsim_ase/vco file and find the location:

dir=`dirname "$arg0"`

After that line add

export LD_LIBRARY_PATH=/opt/altera/18.1/modelsim_ase/lib32

and Fix linux rh60 problem in that file.

You can set the PATH variable as in the 13.0sp1 installation in .profile. If you install two versions, then you can append the following to .bashrc

alias v13="ln -rsvfT /opt/altera/13.0sp1 /opt/altera/version"
alias v18="ln -rsvfT /opt/altera/18.1 /opt/altera/version"

You need to open a new bash to make the changes active. Then you can switch between the versions by running v18 or v13.
