Performance-constrained template-driven retargeting for analog and RF layouts
Bibliographic record
Abstract
Performance of analog and RF integrated circuits is highly sensitive to layout parasitics. This paper presents a complete template-driven algorithm that automatically conducts performance-constrained parasitic-aware retargeting and optimization for analog and RF layouts. In order to ensure desired circuit performance even at high frequency, a lumped interconnect RLC model is deployed and geometric expressions of inductive parasitics are incorporated into optimization. Piecewise performance sensitivities with respect to layout parasitics are determined. Then the algorithm applies numeric performance sensitivities to control parasitic-related layout geometries by constructing performance constraints. The formulated problem is finally solved using a graph-based technique and mixed-integer nonlinear programming. The proposed method has been incorporated into a parasitic-aware automatic layout optimization and retargeting tool. It has been demonstrated to be effective and efficient especially when adapting layout design for new technologies or updated specifications.

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.
