Abstract

fetched live from OpenAlex

As an indispensable portion in the modern system-on-chip designs, analog circuits are becoming more intractable and error prone in the time-consuming design process due to the nature of high parasitic sensitivity along with the shrinking design window in the advanced technology. Compared to the digital counterpart, analog circuits need to be designed more carefully taking into account special analog constraints besides the typical geometric requirements. Recent state-of-the-art analog routing research favors linear programming (LP) to satisfy various constraints, but leaving the routing efficiency as an open question. In this paper, we propose an integer linear programming (ILP) based algorithm to tackle the analog routing problem with a special focus on improving the routing efficiency. Hierarchical routing is developed to help the router to divide the entire routing area into multiple small regions, in each of which the ILP can derive a routing solution with speedy efficiency. Different from typical hierarchical methods, our proposed router deploys variant-grid resolution in different regions, that is, with a lower resolution for less crowded routing regions and a higher resolution for more congested regions. In this way, our proposed ILP-based router is much faster than any typical ones since it spends little time for the areas that do not need to be routed precisely. The experimental results show the high efficiency of our proposed method for both small circuits and especially big circuits without promising the routing quality.

Not 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.
