Rad-hard parts also make for bigger boards and more boards and more
cables and higher power consumption because they don't put nearly as
much functionality on each chip. The added design complexity is
particularly bad -- *most* electronics problems nowadays are design
errors, not random failures, and the more designing you have to do, the
better the chance that you'll goof somewhere.
I've worked around that by way of using Actel Antifuse FPGA ( ACT Series
) They come in all the regular incarnations and a (883) Rad Hard(ened)
Series.
( The "antifuse" tech makes them nonvolatile while still having
acceptable complexity. contrast to ram cell based FPGA
Everything beyond Analog IO into the FPGA. Minimum Chip count.
