FPGA Workshop

Basic FPGA development for absolute beginners

Sections

Pre-requisites

When joining the workshop as a participant make sure to have these things done.

Compiling the tool chain takes 35 to 55 minutes, during which you cannot take part in the exorcizes in the workshop.

  • Installed Icestorm toolchain, that supports the Lattice ICE40UP5K FPGA.
    • Install manually
    • Install by script
    • Install by packagemanager: apt-get install arachne-pnr arachne-pnr-chipdb iverilog gtkwave (on Ubuntu 19.04 or a recent Debian)
    • For those that forget there will be a Virtual machine, that will suffice during the workshop.
  • A micro USB cable
  • A working laptop that can run the Icestorm toolchain (Linux or OSX should be fine, for Windows I don't know#)
  • 3 to 4 hours of your time, an Saturday the 13th (There will be some breaks)
  • Some basic knowledge about programming and digital circuits
  • A laptop that is capable of running the Icestorm toolchain.

Checking the tool chain

A simple check to see if the toolchain supports the 'ICE40UP5K', do:

$ arachne-pnr -h

<...>
    -d <device>, --device <device>
        Target device <device>.  Supported devices:
          384 - Lattice Semiconductor iCE40LP384
           1k - Lattice Semiconductor iCE40LP/HX1K
           5k - Lattice Semiconductor iCE40UP5K
         lm4k - Lattice Semiconductor iCE40LM4K
           8k - Lattice Semiconductor iCE40LP/HX8K
        Default: 1k
<...>

When it shows the line '5k - Lattice Semiconductor iCE40UP5K' the tool chain supports the UPDuino V2.

Simulation

For example 11 you'll need to install Icarus Verilog and GTKWave

Icarus Verilog

git clone git://github.com/steveicarus/iverilog.git iverilog
cd iverilog
sh autoconf.sh
./configure
make -j$(nproc)
sudo make install

GTKWave

svn checkout svn://svn.code.sf.net/p/gtkwave/code/ gtkwave-code
cd gtkwave-code/gtkwave3-gtk3
./configure
make -j$(nproc)
sudo make install
