June 2004[Direct Feature] Soft Error Hits The Ground
Users of ICs at high altitude are aware of the potential for errors caused by the presence of high-energy neutrons. Now there is concern such phenomena could compromise the reliability of systems at ground level. Research, focusing on the phenomenon as it affects the SRAM cells used to program some FPGAs, suggests there may be a problem at ground level. Historically, interest in neutron-induced errors has focused on data corruption in memory devices. Such corruption occurs when...
June 2004[Direct Feature] The Xilinx View On Neutron SEUs
The effect of cosmic radiation on ICs is nothing new to the industry or Xilinx: in radiation-intense environments like the upper atmosphere and in space, SEU events are common and systems must be designed to compensate on the ground, this effect is far less intense. Cosmic Rays striking the atmosphere generate a neutron flux that peaks at 60K feet and decrease to a small fraction at ground level. The energy generated by these particles upon collision with an IC...
