Abstract
This article presents a novel deep-reinforcement-learning-based method for topology synthesis of analog-integrated circuits, especially operational amplifiers (OpAmps). It behaves like a human designer, who learns from trials, derives design knowledge and experience, and evolves gradually to finally figure out optimal manners to construct proper circuit topologies that meet design specifications. Essential design rules are defined and applied to set up the specialized environment for reinforcement learning in order to reasonably construct circuit topologies with building blocks as the basic components. Our proposed method can not only handle large-size circuit designs but also generate creative circuit topologies. The produced circuit topologies are verified by the simulation-in-loop sizing. In order to improve the evaluation efficiency, hash table and symbolic analysis techniques are utilized to significantly reduce the number of the produced topologies to be sized during the synthesis process. Compared with the state-of-the-art approaches, our proposed method significantly improves the synthesis efficiency by consuming only several hours on average to produce a trustworthy solution. Our experimental results demonstrate its sound efficiency, strong reliability, and wide applicability.

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
