I had fun years ago with FPGA's, first on a digilent nexus 3 and then a terasic de0 nano. I kinda gave up as the IDE's sucked and sucked harder if you were on anything other than windows. I spent hours getting Quartus running on Ubuntu, something to do with the draconian licensing software. I also had issues with ISE on Linux and never bothered to move on to Vivaldo for the same reason, didn't want the headache.

Open your stupid bitstream formats FFS.
