A fully automated logic design methodology for radiation hardened by design high-speed logic using fine-grained triple modular redundancy (TMR) is presented. The methodology and circuits leverage commercial logic design automation tools. The circuit approach is validated for hardness using both heavy ion and proton broad beam testing. The base TMR self-correcting master-slave flip-flop is described, including testability features that disable the self-correction. The flow allows hardening of any synthesizable logic at clock frequencies comparable to unhardened designs and supports standard low-power techniques, e.g., clock gating and supply voltage scaling.
