An FPGA-Accelerated Platform for Post-FEC BER Analysis of 200 Gb/s Wireline Systems
Bibliographic record
Abstract
As wireline communication links transition from 100 Gb/s to 200 Gb/s per lane, new and complex forward error correction (FEC) architectures have been proposed to achieve acceptably low bit error rates (BERs). It is essential to understand how these architectures impact link performance under various channel conditions. However, existing methods of post-FEC BER analysis are unsuitable for this application. To address this, we present a flexible platform for FPGA-accelerated post-FEC BER analysis of 200 Gb/s wireline systems. This platform can accurately demonstrate post-FEC BERs at the 10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">–12</sup>level within a day of simulation time, a speed improvement of 10,000X over software-based simulation platforms.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
