Setup and installation of Icarus Verilog
If you installed the recommended oss-cad-suite during SpinalHDL setup you can skip the instructions below - but you need to activate the oss-cad-suite environment.
In most recent linux distributions, a recent version of Icarus Verilog is generally available through the package system. The C++ library boost-interprocess, which is contained in the libboost-dev package in debian-like distributions, has to be installed too. boost-interprocess is required to generate the shared memory communication interface.
sudo apt-get install build-essential libboost-dev iverilog
Also the openjdk package that corresponds to your Java version has to be installed. Refer to https://iverilog.fandom.com/wiki/Installation_Guide for more informations about Windows and installation from source.
