9 years agoXilinx and Actel (Microsemi) have done extensive radiation testing on some of their families. To my knowledge Altera has not, but if I'm wrong about that hopefully someone who knows better will chime in.
Edit: I may have underestimated how much testing Altera does in this area: https://www.altera.com/support/quality-and-reliability/seu.html But whenever I've read about space and other rad-hard applications for FPGAs, Xilinx and Actel have been the only players mentioned.
