Abstract
Manufacturers of field programmable gate arrays
(FPGAs) take different technological and architectural
approaches that directly affect radiation performance. Similar
technological and architectural features are used in related
technologies such as programmable substrates and quick-turn
application specific integrated circuits (ASICs). After
analyzing current technologies and architectures and their
radiation-effects implications, this paper includes extensive
test data quantifying various devices’ total dose and single
event susceptibilities, including performance degradation
effects and temporary or permanent re-configuration faults.
Test results will concentrate on recent technologies being used
in space flight electronic systems and those being developed
for use in the near term.
This paper will provide the first extensive study of
various configuration memories used in programmable
devices. Radiation performance limits and their impacts will
be discussed for each design. In addition, the interplay
between device scaling, process, bias voltage, design, and
architecture will be explored. Lastly, areas of ongoing
research will be discussed.
