Fault tolerant design implementation on radiation hardened by design SRAM-Based FPGAs
TLDR
In this paper, the Xilinx Virtex-5QV is the first commercially available Radiation Hardened By Design (RHBD) SRAM-based FPGA; however, not all of its internal components are hardened against radiation-induced errors.Abstract:
SRAM-based FPGAs are highly attractive for space
applications due to their in-flight reconfigurability, decreased
development time and cost, and increased design and testing
flexibility. The Xilinx Virtex-5QV is the first commercially
available Radiation Hardened By Design (RHBD) SRAM-based FPGA;
however, not all of its internal components are hardened against
radiation-induced errors. This thesis examines and quantifies the
additional considerations and techniques designers should employ
with a RHBD SRAM-based FPGA in a space-based processing system to
achieve high operational reliability. Additionally, this work
presents the application of some of these techniques to the
embedded avionics design of the REXIS imaging payload on the
OSIRIS-REx asteroid sample return mission.read more
