Radiation-Tolerant (RT) ProASIC^® 3 FPGAs

RT ProASIC 3 FPGAs offer designers of space flight hardware a radiation-tolerant, reprogrammable, nonvolatile logic integration vehicle. They are well suited for low-power space applications requiring up to 35k Logic Elements (LEs).

SEE Mitigation Strategies

Mitigation of observed Single-Event Effects (SEEs) may be required depending on the flight-critical nature of the application. If required, mitigation can be accomplished by the instantiation of Triple-Module Redundancy (TMR) of the clock network, the I/O banks and the D-type flip-flops. Synthesis tools have the ability to generate triple-module redundant data paths. However, TMR is not the most efficient way of achieving mitigation in the combinatorial logic and the embedded SRAM memory. Alternative strategies exist for nonvolatile FPGAs, such as dual-redundant, combinatorial pathways using guard gates and short delay elements. Such strategies are explained in more detail in the radiation reports.
