Description
This presentation will address the advantages and disadvantages of flash-based FPGAs versus antifuse FPGAs, in particular regarding radiation resistance.
Using reprogrammable FPGAs provides the ability to perform design update late in the equipment development process, but it also brings several constraints that do not have to be taken into account when using the well-known Microsemi RTAX-S FPGAs.
RTAX-S FPGA (anti-fuse) has to be configured (programmed) before being soldered on the board which is the main drawback in case of late bug discovery. Microsemi RT ProASIC3 (reprogrammable flash cells) allows late FPGA functionality modifications without hardware impact since the device can be re-programmed on board. But using reprogrammable FPGAs also brings several constraints related to radiation effects mitigation (no native TMR as for RTAX FPGA) and mitigation structure implementation verification.
From FPGA selection trade-off to flight design implementation, the presentation will explain how Syderal managed the mitigation technique selection and implementation for two FPGAs designs.
