Abstract
Long distance interconnect delays are not scaling well with process technology, thereby leading to long routes strongly impacting the critical path of large FPGA designs. This forces the designer to pipeline long connections, which necessitates time consuming logic redesign in traditional latency-sensitive systems. Latency-insensitive design (LID) is an increasingly attractive alternative as the typical latency of long distance interconnect grows, since LID decouples the design of the interconnect from that of the computational modules. By doing so, LID simplifies timing closure, improves forward compatibility (migration of systems to future FPGAs) and makes automated system-level pipelining feasible. Modern FPGAs, such as Stratix 10 which includes pipelined interconnect, make it difficult to use traditional LID solutions without significant area and frequency overhead. We present two LID styles that are more suitable for FPGAs and compare them to traditional LID. Our best system gained 2x area efficiency and 18% speed efficiency over traditional LID. Additionally, our designs come at a minimal speed overhead of only 3% compared to that of a latency-sensitive design.

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
