NanoXplore has developed Radiation-Hardened By Design SRAM-based FPGA devices for harsh environments applications for several target technologies like 65nm and 28nm.
By nature, SRAM-based FPGAs are volatile. NanoXplore has designed a dedicated architecture based on hardening techniques such as:
DICE (Dual Interlocked storage CEll) memory latch. DICE architecture has been used for Configuration Memory Cells and Internal registers (DFFs)
EDAC for BRAM blocks
TMR (Triple Module Redundancy) for all other blocks
Based on this hardening approach, our rad-hard SRAM FPGA are much more reliable than traditional SRAM FPGA in harsh environment.
To even furhter improve the reliability of our FPGA, NanoXplore has developped an advanced Configuration Memory Integrity Check ("CMIC"). CMIC is an internal scrubber controller based on a Finite State Machine with its own hardened memory block to store CRC signatures. The CMIC will constantly verify the integrity of the bitstream and any potnential single errors will be detected and corrected.
The following table provides the list of all rad hard FPGAs provided by NanoXplore.
