I suppose you could, but all FPGA manufacturers sell space versions of their FPGAs. Do you know of anyone using non-space-grade? https://www.xilinx.com/applica

- Rebelgecko 8y agoI haven't been following this space that closely for a few years, but when I was more familiar with the offerings from Xilinx and Altera, anything rad-hard was at least 2 generations behind. This led to correspondingly worse performance and SWaP (size, weight, and power). Some of the fancier SOCs like Xilinx Zynqs didn't have any rad-hard version at all. Using consumer or automotive grade chips is not unheard of, especially for lower budget things in LEO like cubesats.
- shaklee3 8y agoThey're behind, but you may end up installing far more of the non-hardened versions, and do the redundancy yourself. That seems like a tough trade-off to do given that there's no fixing it once it's there.
