ArchLinux is not officially supported by [Lattice Diamond](http://www.latticesemi.com/), but as happens with other HDL suites like [Xilinx ISE WebPACK](/index.php/Xilinx_ISE_WebPACK "Xilinx ISE WebPACK") or [Xilinx Vivado](/index.php/Xilinx_Vivado "Xilinx Vivado"), most of its features can be used with a bit of hacking. ## Contents * [1 Prerequisites](#Prerequisites) * [2 Installation](#Installation) * [2.1 Licensing](#Licensing) * [3 Troubleshooting](#Troubleshooting) * [3.1 Place & Route fails](#Place_.26_Route_fails) * [3.2 Programming with FTDI cables doesn't work](#Programming_with_FTDI_cables_doesn.27t_work) ## Prerequisites Lattice provides only 64-bit builds of the suite. So you will need a working 64-bit installation of Arch Linux. ## Installation Just install [lattice-diamond](https://aur.archlinux.org/packages/lattice-diamond/). Note that the installation size is big (around 4 GB), so generating the package might take some time due to the compression stage. If you want to shorten building the package, edit the PKGBUILD file to avoid compressing it. ### Licensing You can request a free license to [Lattice Semiconductor](http://www.latticesemi.com/Support/Licensing.aspx) (registration needed). These licenses are node-locked (tied to the MAC of your Ethernet card). Once you have the license file, copy it to `/usr/local/diamond/3.10_x64/license/license.dat`, or you will not be able to start the suite. ## Troubleshooting ### Place & Route fails If Place & Route fails with message `ERROR - par: Switch "-msgsegset" is not allowed.`, try deleting the `promote.xml` file in the root directory of your project and launch it again. It should now run normally. ### Programming with FTDI cables doesn't work Programming FPGAs with FTDI chip based cables will not work if `ftdi_sio` kernel module is loaded. **After** plugging the programmer run: ``` # rmmod ftdi_sio ``` Now the programmer should work until you re-attach it again (so you must run the command above every time the programmer is plugged).
