Abstract
This paper presents a family of modular, standard-cell-based interfaces for crossing between asynchronous and synchronous timing domains. These FIFOs have interchangeable input and output interfaces for edge-triggered synchronous communication and for the asP* asynchronous pulse-based handshake protocol. The FIFO capacity, synchronizer latency and interface protocols are independent parameters, allowing the FIFO to be easily configured for different requirements. The modular design makes the FIFO ideal for use in system-on-chip applications, where multiple functional blocks operating at different clock frequencies communicate using an asynchronous network-on-chip. They provide high-throughput communication and hide most of the synchronization latency. Our designs are fully synthesizable using widely available standard cell libraries and a standard ASIC design flow. We generate layoutS for several different synchronous and asynchronous FIFOs. All instances can operate at speeds greater than 1.45 GHz under worst-case conditions when implemented in a 65nm CMOS process.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
