There's no free alternatives, because AMD doesn't document the bitstream format (i.e. what you need to push to the FPGA to program it to do wha you want).

- rob_c 4mo agoI'm fairly sure the FPGA space is big enough there are alternate products for most of the offerings
- tliltocatl 4mo agoXilinx has the best silicon. Everyone else is behind. Altera is basically dead thanks Intel. Lattice is nice for low power but performance-wise they are behind. Don't know much about Microchip, but from the little I've heard their tooling is a disaster even by the standards of FPGA tooling. Then there are Gowin (not bad, but Chinglish docs and everything), Gatemate (pretty innovative and vendor-backed nextpnr support - but only one low-mid FPGA with a promise to release chiplet assemblies of it latter). And Effinix - don't know much about them, do anyone have experience?
- IshKebab 4mo agoIt's not. There's a duopoly between AMD (Xilinx) and Intel (Altera). There's more choice at the very low end but if you're going for a powerful FPGA (which is mostly what people need) those are the choices.
