Cet article présente une nouvelle évaluation de la régularité de la structure de placement et des techniques de gestion des règles de conception conditionnelles ainsi que du partage de diffusion dynamique et de la génération d'îlots de puits, qui sont développés sur la base de Sequence-Pair. Les structures régulières telles que les lignes topologiques, les tableaux et les structures répétitives sont caractérisées par la manière de former des sous-séquences d'une paire de séquences. Un objectif de placement est formulé équilibrant la régularité et l'efficacité du territoire. En outre, le partage de diffusion et l'îlot de puits peuvent également être identifiés en étudiant la formation d'une paire de séquences. Lors d'expériences, nous avons appliqué notre placement orienté régularité combiné à la technique basée sur les contraintes à des conceptions analogiques réelles et avons obtenu des résultats comparables à ceux des conceptions manuelles, même en imposant des contraintes de symétrie. En outre, les résultats ont également révélé que la régularité sert à augmenter les structures en rangées applicables au partage de diffusion pour économiser de la surface et réduire la longueur des fils.

Abstract: This paper presents a novel regularity evaluation of placement structure and techniques for handling conditional design rules along with dynamic diffusion sharing and well island generation, which are developed based on Sequence-Pair. The regular structures such as topological rows, arrays and repetitive structures are characterized by the way of forming sub-sequences of a sequence-pair. A placement objective is formulated balancing the regularity and the area efficiency. Furthermore, diffusion sharing and well island can be also identified looking into forming of a sequence-pair. In experiments, we applied our regularity-oriented placement mixed with the constraint-driven technique to real analog designs, and attained the results comparable to manual designs even when imposing symmetry constraints. Besides, the results also revealed the regularity serves to increase row-structures applicable to the diffusion sharing for area saving and wire-length reduction.
