Regularity-Oriented Analog Placement with Conditional Design Rules
Summary :
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.
