Create a folder where you want to install the Icarus Verilog, for example /opt/iverilog (you might need sudo to create this folder and copy data to it).

$ sudo mkdir /opt/iverilog

Navigate to your download folder. Decompress the downloaded archive (replace ARCHIVE by the actual archive name). Again, you might have to use sudo if your target directory is protected.

$ sudo tar -xzf ARCHIVE.tar.gz -C /opt/iverilog/

Now add the simulator's bin folder to your system's PATH environment variable. Your can also add this line to your .bashrc if applicable.

$ export PATH=$PATH:/opt/iverilog/bin

Test the simulator:

$ iverilog -v
Icarus Verilog version 12.0 (devel) (s20150603-1558-gc7cdc6c23)
