@lispi314 @HopperMCS @rher @Zergling_man That's not really relevant to the article, as FGPAs are like any other computer hardware that runs software.

Ideally you would have a free FGPA design, get that fabbed and then run whatever free designs on that as software.

The only current line of FGPAs that I'm aware of are fully programmable in freedom is the ICE40 line, too bad no model has enough logic gates for a really complicated hardware design.
