This repository contains a simple but flexible script that builds a open-source FPGA tools. These tools consist from:

  • Yosys
  • prjtrellis
  • nextpnr-ice40
  • nextpnr-ecp5
  • arachne-pnr
  • icestorm
  • icarus-verilog

More tools will be added over time. The current candidates are:

  • verilator
  • gtkwave

This script is intended to not require super user privileges and installs all the tools into ${HOME}/sft directory. Obviously you will need some rights to install the dependencies provided by your operating system.

As many of the tools don't have official release tarballs, and the tools are still in very rapid development we are currently building the newest master releases of all the tools.


You will need to install the following dependencies to be able to run this script.

Mac OS

XCode with command line tools.

brew install cmake python boost boost-python3 qt5 git libftdi0 bison gperf \
	     eigen pkg-config libffi autoconf

For additional information regarding Mac OS, refer to the project IceStorm documentation.

To compile the open source FPGA tools:

  • git clone or
  • wget; unzip master
  • cd summon-fpga-tools
  • ./
  • export PATH=~/sft/bin:$PATH
  • Profit

Command line options

You can suffix the script call with the following variable parameters:


By default the installation prefix is ${HOME}/sft you can change it to /usr or /usr/local then the binaries will be installed into ${HOME}/sft/bin, /usr/bin or /usr/local/bin respectively.


By default this variable is empty. If you need root rights for the install step you may set this variable to sudo.

$ ./ SUDO=sudo

This will prefix all make install steps with the sudo command asking for your root password.


By default set to 0. To decrease console output (may increase compile speed in some cases) you can set this variable to 1.


Overrides the autodetection of CPU cores on the host machine. This option is translated into the -j$CPUS+1 option to the make command when running the script.


If building for a headless machine, set to off and skip the QT dependencies above.


$ ./ CPUS=5

This will run the script with 5 CPUs on your host machine resulting in calling all make commands with -j6.


I am running iceprog and the programmer is not being detected

  • Check if the device is being detected by the kernel with 'lsusb' it will either show up as a Future Electronics device or the name of the programmer vendor.
  • If the device is being detected by the kernel you might not have permissions to access the device. If you run sudo iceprog ... and the device is decected you can give yourself permissions by creating a udev file at: /etc/udev/rules.d/53-lattice-ftdi.rules and adding the following line in that file:
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010", MODE="0660", GROUP="plugdev", TAG+="uaccess"

After adding that file you need to at least replug the programmer or even reload the udev rules.

I am getting an error during iverilog installation

IcarusVerilog build system is little bit broken when running on multiple processes as it's dependencies are not set up correctly. You might need to run the summon-fpga-tools script twice so that the installation succeeds. If the issue persists after the second try, consider opening an issue either for iverilog or SFT, and we will try to get it sorted out. :)
