![]() Instead I'd like to use $HOME/.local: # dry run. I don't want to install the tools in /usr/local because that's owned by homebrew. PYTHONPATH=`brew -prefix`/lib/python$PYTHONVERSION/site-packages/ make -j Unfortunately, arachne-pnr and icestorm are not available on homebrew, yet, so we have to build them ourselves. You can use the following steps to install all four: Prerequisites brew install bison gawk pkg-config git mercurial graphviz python python3 libftdi0 libffiįortunately yosys and iverilog are already packaged in homebrew: brew install yosys icarus-verilog If you use Mac homebrew it is not a good idea to install into /usr/local. You can also install the tools apt-get install verilog If you also want to visualize simulated waveforms you have to install a fifth tool GTKWave. If you want to compile and install all four yourself and install in the default /usr/local location, then you can use Dimitri del Marmol's excellent icetools set of scripts. icestorm: Tools for generating and manipulating iCE40 bitstreams.arachne-pnr: Place and route tool for FPGAs.Icarus Verilog: Verilog simulation and synthesis tool.At the end some further resources are collected.įPGA stands for "Field Programmable Gate Array", it is essentially a huge array of logic gates which can be arbitrarily connected to make a circuit of your choice. ![]() Then a simple blinky program is synthesized, routed and programmed on a Lattice iCEStick. First we will cover installation of the toolchain on Linux and Mac OS X. ![]() This blog post gets you started with Project IceStorm, a fully open source Verilog-to-Bitstream flow for iCE40 FPGAs. ![]()
