Abstract
Despite all efforts being made to ease analog layout generation, the designers' expertise is still highly demanded in the process of analog IC physical design. Recently, some endeavors started to leverage artificial intelligence (AI) to tackle the complexity of analog layout optimization and alleviate the high demand for the designers' experience in the design process. However, these methods, which mainly rely on using the previous designs, are not effective to the unseen data (or scenarios) that were not included in the AI training. In this paper, we have proposed a reinforcement-learning-based method that can fully automate analog layout placement optimization. It is not only applicable to any unseen analog placement scenarios, but also can meet the requirements of analog layout placement designs in the advanced FinFET technology. Our experimental results show that the proposed method can place analog modules subject to the defined objectives 77x faster than the conventional analytical methods (e.g., conjugate gradient) without compromising the optimization accuracy.

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
