Mitigation of Single-Event Charge Sharing in a Commercial FPGA Architecture

The motivation for single event effects (SEE) analysis and mitigation as part of the process for adaptation of a commercial Field Programmable Gate Array (FPGA) architecture for space-qualified applications is discussed. The interdependent roles of heavy-ion and laser-induced upset evaluation coupled with computer-aided investigations of SEE mechanisms and mitigation techniques in this process are shown to enable a significant reduction in SEE sensitivity of the device, while achieving minimal impact on remanufacturing steps.
