Well, nothing stops voting machine design in Vhdl. Move the hardware software partition 100% to the hardware side. Prove a design formally

  Right, but the point of the article is that it would be expensive to do that. VHDL, although not difficult to learn is a specialized skill that many technical people do not have. It’s very dissimilar to something like CPP for that reason. You can build a team to do it, but the market is smaller. Then you have FPGAs themselves, which are expensive chips, then you have tool chains, which are proprietary and closed down. This does not help costs and it does not help security. Then you need to attach the fpga to peripherals, like the display, so you need to build a board, solder components to it. There’s a lot of supply chain complexity in building a simple device. That’s the point, and that’s why we don’t see it.
