TSPC-DICE: A single phase clock high performance SEU hardened flip-flop
Bibliographic record
Abstract
This paper presents a true single-phase clock (TSPC) flip-flop that is robust against radiation-induced single event upsets (SEUs) or soft errors. The flip-flop consists of an input stage that uses a single phase clock to pass the data to a storage unit at the positive edge of the clock. The single phase clock enables designing power-efficient and easily-routed clock-tree and reducing the NBTI effect on the setup and hold times. The storage unit consists of the SEU robust dual interlocked cell (DICE), which has four nodes that replicate the data bit and its complement for recovering from a single event transient (SET). Two nodes with the same logic value inside the storage unit drive a C-element at the output. The C-element masks the propagation of any SET from the internal nodes of the storage unit to the output. The proposed flip-flop consists of only 22 transistors, consumes smaller area, and exhibits as much as 12% lower power-delay product when compared with a recently reported SEU robust flip-flop implemented in a commercial 65nm CMOS technology.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
