1. Download Lattice Dianond
wget http://files.latticesemi.com/Diamond/3.12/diamond_3_12-base-240-2-x86_64-linux.rpm
2. Convert rpm to deb
sudo apt install alien lsb
sudo alien --scripts diamond_3_12-base-240-2-x86_64-linux.rpm
sudo dpkg -i diamond-3-12-base_3.12-241_amd64.deb
3. Install Licence
sudo cp ./Downloads/license.dat /usr/local/diamond/3.12/license/
sudo vim /usr/local/diamond/3.12/license/license.dat
nodename --> PC hostname
line 2 daemon_path --> /usr/local/diamond/3.12/ispfpga/bin/lin64
line 2 mgcld_path --> /usr/local/diamond/3.12/modeltech/linuxloem/mgls/bin/mgcld
sudo touch /usr/local/diamond/3.12/license/license.log

4. Change USB driver
sudo adduser <my_user> dialout
sudo vim /etc/udev/rules.d/10-lattice.rules
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6014", MODE="0666", SYMLINK+="ftdi-%n", RUN+="/bin/sh -c 'basename $(dirname $(realpath /sys%p/device)) > /sys/bus/usb/drivers/ftdi_sio/unbind'",RUN+="/opt/ftdi_fixer.py"
sudo curl https://ycc.io/scripts/ftdi_fixer.py -o /opt/ftdi_fixer.py
sudo chmod +x /opt/ftdi_fixer.py
sudo udevadm control --reload
5. Start Lattice Diamond
