Formal Verification Framework and Radiation Hardening Architecture for High-Speed FPGA-Based Plasma Stability Controllers

This technical report specifies the reliability architecture of the Catechon framework (v4.5-Hardened). It details the implementation of SystemVerilog Assertions (SVA) for formal safety verification and Single Event Upset (SEU) mitigation strategies. Key features include Triple Modular Redundancy (TMR) for control registers and Hamming (22,16) SEC-DED error correction for data paths, designed for stable operation in high-neutron flux environments (ITER/APS/SPARC class)
